You probably use [Alamofire](https://github.com/Alamofire/Alamofire) to abstract away access to +`URLSession` and all those nasty details you don't really care about. But then, +like lots of smart developers, you write ad hoc network abstraction layers. They +are probably called "APIManager" or "NetworkModel", and they always end in tears. + +![Moya Overview](web/diagram.png) + +Ad hoc network layers are common in iOS apps. They're bad for a few reasons: + +- Makes it hard to write new apps ("where do I begin?") +- Makes it hard to maintain existing apps ("oh my god, this mess...") +- Makes it hard to write unit tests ("how do I do this again?") + +So the basic idea of Moya is that we want some network abstraction layer that +sufficiently encapsulates actually calling Alamofire directly. It should be simple +enough that common things are easy, but comprehensive enough that complicated things +are also easy. + +> If you use Alamofire to abstract away `URLSession`, why not use something +to abstract away the nitty gritty of URLs, parameters, etc? + +Some awesome features of Moya: + +- Compile-time checking for correct API endpoint accesses. +- Lets you define a clear usage of different endpoints with associated enum values. +- Treats test stubs as first-class citizens so unit testing is super-easy. + +You can check out more about the project direction in the [vision document](https://github.com/Moya/Moya/blob/master/Vision.md). + +## Sample Projects + +We have provided two sample projects in the repository. To use it download the repo, run `carthage update` to download the required libraries and open [Moya.xcodeproj](https://github.com/Moya/Moya/tree/master/Moya.xcodeproj). You'll see two schemes: `Basic` and `Multi-Target` - select one and then build & run! Source files for these are in the `Examples` directory in project navigator. Have fun! + +## Project Status + +This project is actively under development, and is being used in [Artsy's +new auction app](https://github.com/Artsy/eidolon). We consider it +ready for production use. + +## Installation + +### Moya version vs Swift version. + +Below is a table that shows which version of Moya you should use for +your Swift version. + +| Swift | Moya | RxMoya | ReactiveMoya | +| ----- | -------------- |---------------- |--------------- | +| 5.X | >= 13.0.0 | >= 13.0.0 | >= 13.0.0 | +| 4.X | 9.0.0 - 12.0.1 | 10.0.0 - 12.0.1 | 9.0.0 - 12.0.1 | +| 3.X | 8.0.0 - 8.0.5 | 8.0.0 - 8.0.5 | 8.0.0 - 8.0.5 | +| 2.3 | 7.0.2 - 7.0.4 | 7.0.2 - 7.0.4 | 7.0.2 - 7.0.4 | +| 2.2 | <= 7.0.1 | <= 7.0.1 | <= 7.0.1 | + +_Note: If you are using Swift 4.2 in your project, but you are using Xcode 10.2, Moya 13 should work correctly even though we use Swift 5.0._ + +**Upgrading to a new major version of Moya? Check out our [migration guides](https://github.com/Moya/Moya/blob/master/docs/MigrationGuides).** + +### Swift Package Manager + +To integrate using Apple's Swift package manager, add the following as a dependency to your `Package.swift`: + +```swift +.package(url: "https://github.com/Moya/Moya.git", .upToNextMajor(from: "14.0.0")) +``` + +and then specify `"Moya"` as a dependency of the Target in which you wish to use Moya. +If you want to use reactive extensions, add also `"ReactiveMoya"` or `"RxMoya"` as your Target dependency respectively. +Here's an example `PackageDescription`: + +```swift +// swift-tools-version:5.0 +import PackageDescription + +let package = Package( + name: "MyPackage", + products: [ + .library( + name: "MyPackage", + targets: ["MyPackage"]), + ], + dependencies: [ + .package(url: "https://github.com/Moya/Moya.git", .upToNextMajor(from: "14.0.0")) + ], + targets: [ + .target( + name: "MyPackage", + dependencies: ["ReactiveMoya"]) + ] +) +``` + +Note: If you are using **ReactiveMoya**, we are using [our own fork of ReactiveSwift](https://github.com/Moya/ReactiveSwift). This fork adds 2 commits to remove testing dependencies on releases (starting 6.1.0). This is to prevent Xcode Previews on Xcode 11/11.1 to build testing dependencies (FB7316430). If you don't want to use our fork, you can just add another dependency to your SPM package list: `git@github.com:ReactiveCocoa/ReactiveSwift.git` and it should fetch the original repository. + +### Accio + +[Accio](https://github.com/JamitLabs/Accio) is a dependency manager based on SwiftPM which can build frameworks for iOS/macOS/tvOS/watchOS. Therefore the integration steps of Moya are exactly the same as described above. Once your `Package.swift` file is configured, run `accio update` instead of `swift package update`. + +### CocoaPods + +For Moya, use the following entry in your Podfile: + +```rb +pod 'Moya', '~> 14.0' + +# or + +pod 'Moya/RxSwift', '~> 14.0' + +# or + +pod 'Moya/ReactiveSwift', '~> 14.0' +``` + +Then run `pod install`. + +In any file you'd like to use Moya in, don't forget to +import the framework with `import Moya`. + +### Carthage + +Carthage users can point to this repository and use whichever +generated framework they'd like, `Moya`, `RxMoya`, or `ReactiveMoya`. + +Make the following entry in your Cartfile: + +``` +github "Moya/Moya" ~> 14.0 +``` + +Then run `carthage update`. + +If this is your first time using Carthage in the project, you'll need to go through some additional steps as explained [over at Carthage](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application). + +> NOTE: At this time, Carthage does not provide a way to build only specific repository submodules. All submodules and their dependencies will be built with the above command. However, you don't need to copy frameworks you aren't using into your project. For instance, if you aren't using `ReactiveSwift`, feel free to delete that framework along with `ReactiveMoya` from the Carthage Build directory after `carthage update` completes. Or if you are using `ReactiveSwift` but not `RxSwift`, then `RxMoya`, `RxTest`, `RxCocoa`, etc. can safely be deleted. + +### Manually + +- Open up Terminal, `cd` into your top-level project directory, and run the following command *if* your project is not initialized as a git repository: + +```bash +$ git init +``` + +- Add Alamofire, Result & Moya as a git [submodule](http://git-scm.com/docs/git-submodule) by running the following commands: + +```bash +$ git submodule add https://github.com/Alamofire/Alamofire.git +$ git submodule add https://github.com/antitypical/Result.git +$ git submodule add https://github.com/Moya/Moya.git +``` + +- Open the new `Alamofire` folder, and drag the `Alamofire.xcodeproj` into the Project Navigator of your application's Xcode project. Do the same with the `Result.xcodeproj` in the `Result` folder and `Moya.xcodeproj` in the `Moya` folder. + +> They should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter. + +- Verify that the deployment targets of the `xcodeproj`s match that of your application target in the Project Navigator. +- Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar. +- In the tab bar at the top of that window, open the "General" panel. +- Click on the `+` button under the "Embedded Binaries" section. +- You will see two different `Alamofire.xcodeproj` folders each with two different versions of the `Alamofire.framework` nested inside a `Products` folder. + +> It does not matter which `Products` folder you choose from, but it does matter whether you choose the top or bottom `Alamofire.framework`. + +- Select the top `Alamofire.framework` for iOS and the bottom one for macOS. + +> You can verify which one you selected by inspecting the build log for your project. The build target for `Alamofire` will be listed as either `Alamofire iOS`, `Alamofire macOS`, `Alamofire tvOS` or `Alamofire watchOS`. + +- Click on the `+` button under "Embedded Binaries" again and add the build target you need for `Result`. +- Click on the `+` button again and add the correct build target for `Moya`. + +- And that's it! + +> The three frameworks are automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device. + +## Usage + +After [some setup](https://github.com/Moya/Moya/blob/master/docs/Examples/Basic.md), using Moya is really simple. You can access an API like this: + +```swift +provider = MoyaProvider() +provider.request(.zen) { result in + switch result { + case let .success(moyaResponse): + let data = moyaResponse.data + let statusCode = moyaResponse.statusCode + // do something with the response data or statusCode + case let .failure(error): + // this means there was a network failure - either the request + // wasn't sent (connectivity), or no response was received (server + // timed out). If the server responds with a 4xx or 5xx error, that + // will be sent as a ".success"-ful response. + } +} +``` + +That's a basic example. Many API requests need parameters. Moya encodes these +into the enum you use to access the endpoint, like this: + +```swift +provider = MoyaProvider() +provider.request(.userProfile("ashfurrow")) { result in + // do something with the result +} +``` + +No more typos in URLs. No more missing parameter values. No more messing with +parameter encoding. + +For more examples, see the [documentation](https://github.com/Moya/Moya/blob/master/docs/Examples). + +## Reactive Extensions + +Even cooler are the reactive extensions. Moya provides reactive extensions for +[ReactiveSwift](https://github.com/ReactiveCocoa/ReactiveSwift) and +[RxSwift](https://github.com/ReactiveX/RxSwift). + +### ReactiveSwift + +[`ReactiveSwift` extension](https://github.com/Moya/Moya/blob/master/docs/ReactiveSwift.md) provides both `reactive.request(:callbackQueue:)` and +`reactive.requestWithProgress(:callbackQueue:)` methods that immediately return +`SignalProducer`s that you can start, bind, map, or whatever you want to do. +To handle errors, for instance, we could do the following: + +```swift +provider = MoyaProvider() +provider.reactive.request(.userProfile("ashfurrow")).start { event in + switch event { + case let .value(response): + image = UIImage(data: response.data) + case let .failed(error): + print(error) + default: + break + } +} +``` + +### RxSwift + +[`RxSwift` extension](https://github.com/Moya/Moya/blob/master/docs/RxSwift.md) also provide both `rx.request(:callbackQueue:)` and +`rx.requestWithProgress(:callbackQueue:)` methods, but return type is +different for both. In case of a normal `rx.request(:callbackQueue)`, the +return type is `Single` which emits either single element or an +error. In case of a `rx.requestWithProgress(:callbackQueue:)`, the return +type is `Observable`, since we may get multiple events +from progress and one last event which is a response. + +To handle errors, for instance, we could do the following: + +```swift +provider = MoyaProvider() +provider.rx.request(.userProfile("ashfurrow")).subscribe { event in + switch event { + case let .success(response): + image = UIImage(data: response.data) + case let .error(error): + print(error) + } +} +``` + +In addition to the option of using signals instead of callback blocks, there are +also a series of signal operators for RxSwift and ReactiveSwift that will attempt +to map the data received from the network response into either an image, some JSON, +or a string, with `mapImage()`, `mapJSON()`, and `mapString()`, respectively. If the mapping is unsuccessful, you'll get an error on the signal. You also get handy methods +for filtering out certain status codes. This means that you can place your code for +handling API errors like 400's in the same places as code for handling invalid +responses. + +## Community Projects + +[Moya has a great community around it and some people have created some very helpful extensions](https://github.com/Moya/Moya/blob/master/docs/CommunityProjects.md). + +## Contributing + +Hey! Do you like Moya? Awesome! We could actually really use your help! + +Open source isn't just writing code. Moya could use your help with any of the +following: + +- Finding (and reporting!) bugs. +- New feature suggestions. +- Answering questions on issues. +- Documentation improvements. +- Reviewing pull requests. +- Helping to manage issue priorities. +- Fixing bugs/new features. + +If any of that sounds cool to you, send a pull request! After your first +contribution, we will add you as a member to the repo so you can merge pull +requests and help steer the ship :ship: You can read more details about that [in our contributor guidelines](https://github.com/Moya/Moya/blob/master/Contributing.md). + +Moya's community has a tremendous positive energy, and the maintainers are committed to keeping things awesome. Like [in the CocoaPods community](https://github.com/CocoaPods/CocoaPods/wiki/Communication-&-Design-Rules), always assume positive intent; even if a comment sounds mean-spirited, give the person the benefit of the doubt. + +Please note that this project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by [its terms](https://github.com/Moya/Moya/blob/master/Code%20of%20Conduct.md). + +### Adding new source files + +If you add or remove a source file from Moya, a corresponding change needs to be made to the `Moya.xcodeproj` project at the root of this repository. This project is used for Carthage. Don't worry, you'll get an automated warning when submitting a pull request if you forget. + +### Help us improve Moya documentation +Whether you’re a core member or a user trying it out for the first time, you can make a valuable contribution to Moya by improving the documentation. Help us by: + +- sending us feedback about something you thought was confusing or simply missing +- suggesting better wording or ways of explaining certain topics +- sending us a pull request via GitHub +- improving the [Chinese documentation](https://github.com/Moya/Moya/blob/master/Readme_CN.md) + + +## License + +Moya is released under an MIT license.

+ + +> 📣 **IMPORTANT!** +> +> `SkeletonView` is recursive, so if you want show the skeleton in all skeletonable views, you only need to call the show method in the main container view. For example, with `UIViewControllers`. + + + + +### 🌿 Collections + +```SkeletonView``` is compatible with ```UITableView``` and ```UICollectionView```. + + +**UITableView** + +If you want to show the skeleton in a ```UITableView```, you need to conform to ```SkeletonTableViewDataSource``` protocol. + +``` swift +public protocol SkeletonTableViewDataSource: UITableViewDataSource { + func numSections(in collectionSkeletonView: UITableView) -> Int // Default: 1 + func collectionSkeletonView(_ skeletonView: UITableView, numberOfRowsInSection section: Int) -> Int + func collectionSkeletonView(_ skeletonView: UITableView, cellIdentifierForRowAt indexPath: IndexPath) -> ReusableCellIdentifier + func collectionSkeletonView(_ skeletonView: UITableView, skeletonCellForRowAt indexPath: IndexPath) -> UITableViewCell? // Default: nil + func collectionSkeletonView(_ skeletonView: UITableView, prepareCellForSkeleton cell: UITableViewCell, at indexPath: IndexPath) +} +``` +As you can see, this protocol inherits from ```UITableViewDataSource```, so you can replace this protocol with the skeleton protocol. + +This protocol has a default implementation for some methods. For example, the number of rows for each section is calculated in runtime: + +``` swift +func collectionSkeletonView(_ skeletonView: UITableView, numberOfRowsInSection section: Int) -> Int +// Default: +// It calculates how many cells need to populate whole tableview +``` + +> 📣 **IMPORTANT!** +> +> If you return `UITableView.automaticNumberOfSkeletonRows` in the above method, it acts like the default behavior (i.e. it calculates how many cells needed to populate the whole tableview). + +There is only one method you need to implement to let Skeleton know the cell identifier. This method doesn't have default implementation: + ``` swift + func collectionSkeletonView(_ skeletonView: UITableView, cellIdentifierForRowAt indexPath: IndexPath) -> ReusableCellIdentifier { + return "CellIdentifier" +} + ``` + + By default, the library dequeues the cells from each indexPath, but you can also do this if you want to make some changes before the skeleton appears: + ``` swift + func collectionSkeletonView(_ skeletonView: UITableView, skeletonCellForRowAt indexPath: IndexPath) -> UITableViewCell? { + let cell = skeletonView.dequeueReusableCell(withIdentifier: "CellIdentifier", for: indexPath) as? Cell + cell?.textField.isHidden = indexPath.row == 0 + return cell + } + ``` + +If you prefer to leave the deque part to the library you can configure the cell using this method: + ``` swift + func collectionSkeletonView(_ skeletonView: UITableView, prepareCellForSkeleton cell: UITableViewCell, at indexPath: IndexPath) { + let cell = cell as? Cell + cell?.textField.isHidden = indexPath.row == 0 + } + ``` + + +Besides, you can skeletonize both the headers and footers. You need to conform to `SkeletonTableViewDelegate` protocol. + +```swift +public protocol SkeletonTableViewDelegate: UITableViewDelegate { + func collectionSkeletonView(_ skeletonView: UITableView, identifierForHeaderInSection section: Int) -> ReusableHeaderFooterIdentifier? // default: nil + func collectionSkeletonView(_ skeletonView: UITableView, identifierForFooterInSection section: Int) -> ReusableHeaderFooterIdentifier? // default: nil +} +``` + +> 📣 **IMPORTANT!** +> +> 1️⃣ If you are using resizable cells (**`tableView.rowHeight = UITableViewAutomaticDimension`**), it's mandatory define the **`estimatedRowHeight`**. +> +> 2️⃣ When you add elements in a **`UITableViewCell`** you should add it to **`contentView`** and not to the cell directly. +> ```swift +> self.contentView.addSubview(titleLabel) ✅ +> self.addSubview(titleLabel) ❌ +> ``` + + + +**UICollectionView** + +For `UICollectionView`, you need to conform to `SkeletonCollectionViewDataSource` protocol. + +``` swift +public protocol SkeletonCollectionViewDataSource: UICollectionViewDataSource { + func numSections(in collectionSkeletonView: UICollectionView) -> Int // default: 1 + func collectionSkeletonView(_ skeletonView: UICollectionView, numberOfItemsInSection section: Int) -> Int + func collectionSkeletonView(_ skeletonView: UICollectionView, cellIdentifierForItemAt indexPath: IndexPath) -> ReusableCellIdentifier + func collectionSkeletonView(_ skeletonView: UICollectionView, supplementaryViewIdentifierOfKind: String, at indexPath: IndexPath) -> ReusableCellIdentifier? // default: nil + func collectionSkeletonView(_ skeletonView: UICollectionView, skeletonCellForItemAt indexPath: IndexPath) -> UICollectionViewCell? // default: nil + func collectionSkeletonView(_ skeletonView: UICollectionView, prepareCellForSkeleton cell: UICollectionViewCell, at indexPath: IndexPath) +} +``` + +The rest of the process is the same as ```UITableView``` + + +### 🔠 Texts + +![](Assets/multilines2.png) + +When using elements with text, ```SkeletonView``` draws lines to simulate text. +Besides, you can decide how many lines you want. If ```numberOfLines``` is set to zero, it will calculate how many lines needed to populate the whole skeleton and it will be drawn. Instead, if you set it to one, two or any number greater than zero, it will only draw this number of lines. + +You can set some properties for multilines elements. + + +| Property | Values | Default | Preview +| ------- | ------- |------- | ------- +| **Filling percent** of the last line. | `0...100` | `70%` | ![](Assets/multiline_lastline.png) +| **Corner radius** of lines. (**NEW**) | `0...10` | `0` | ![](Assets/multiline_corner.png) + + + +To modify the percent or radius **using code**, set the properties: +```swift +descriptionTextView.lastLineFillPercent = 50 +descriptionTextView.linesCornerRadius = 5 +``` + +Or, if you prefer use **IB/Storyboard**: + +![](Assets/multiline_customize.png) + + +### 🦋 Appearance + +The skeletons have a default appearance. So, when you don't specify the color, gradient or multilines properties, `SkeletonView` uses the default values. + +Default values: +- **tintColor**: UIColor + - *default: `.skeletonDefault` (same as `.clouds` but adaptive to dark mode)* +- **gradient**: SkeletonGradient + - *default: `SkeletonGradient(baseColor: .skeletonDefault)`* +- **multilineHeight**: CGFloat + - *default: 15* +- **multilineSpacing**: CGFloat + - *default: 10* +- **multilineLastLineFillPercent**: Int + - *default: 70* +- **multilineCornerRadius**: Int + - *default: 0* +- **skeletonCornerRadius**: CGFloat (IBInspectable) (Make your skeleton view with corner) + - *default: 0* + +To get these default values you can use `SkeletonAppearance.default`. Using this property you can set the values as well: +```swift +SkeletonAppearance.default.multilineHeight = 20 +SkeletonAppearance.default.tintColor = .green +``` + +You can also specifiy these line appearance properties on a per-label basis: +- **lastLineFillPercent**: Int +- **linesCornerRadius**: Int +- **skeletonLineSpacing**: CGFloat +- **skeletonPaddingInsets**: UIEdgeInsets + + +### 🎨 Custom colors + +You can decide which color the skeleton is tinted with. You only need to pass as a parameter the color or gradient you want. + +**Using solid colors** +```swift +view.showSkeleton(usingColor: UIColor.gray) // Solid +// or +view.showSkeleton(usingColor: UIColor(red: 25.0, green: 30.0, blue: 255.0, alpha: 1.0)) +``` +**Using gradients** +``` swift +let gradient = SkeletonGradient(baseColor: UIColor.midnightBlue) +view.showGradientSkeleton(usingGradient: gradient) // Gradient +``` + +Besides, **SkeletonView** features 20 flat colors 🤙🏼 + +```UIColor.turquoise, UIColor.greenSea, UIColor.sunFlower, UIColor.flatOrange ...``` + +![](Assets/flatcolors.png) +###### Image captured from website [https://flatuicolors.com](https://flatuicolors.com) + + +### 🏃‍♀️ Animations + +**SkeletonView** has two built-in animations, *pulse* for solid skeletons and *sliding* for gradients. + +Besides, if you want to do your own skeleton animation, it's really easy. + + +Skeleton provides the `showAnimatedSkeleton` function which has a ```SkeletonLayerAnimation``` closure where you can define your custom animation. + +```swift +public typealias SkeletonLayerAnimation = (CALayer) -> CAAnimation +``` + +You can call the function like this: + +```swift +view.showAnimatedSkeleton { (layer) -> CAAnimation in + let animation = CAAnimation() + // Customize here your animation + + return animation +} +``` + +It's available ```SkeletonAnimationBuilder```. It's a builder to make ```SkeletonLayerAnimation```. + +Today, you can create **sliding animations** for gradients, deciding the **direction** and setting the **duration** of the animation (default = 1.5s). + +```swift +// func makeSlidingAnimation(withDirection direction: GradientDirection, duration: CFTimeInterval = 1.5) -> SkeletonLayerAnimation + +let animation = SkeletonAnimationBuilder().makeSlidingAnimation(withDirection: .leftToRight) +view.showAnimatedGradientSkeleton(usingGradient: gradient, animation: animation) + +``` + +```GradientDirection``` is an enum, with theses cases: + +| Direction | Preview +|------- | ------- +| .leftRight | ![](Assets/sliding_left_to_right.gif) +| .rightLeft | ![](Assets/sliding_right_to_left.gif) +| .topBottom | ![](Assets/sliding_top_to_bottom.gif) +| .bottomTop | ![](Assets/sliding_bottom_to_top.gif) +| .topLeftBottomRight | ![](Assets/sliding_topLeft_to_bottomRight.gif) +| .bottomRightTopLeft | ![](Assets/sliding_bottomRight_to_topLeft.gif) + +> **😉 TRICK!** +> +> Exist another way to create sliding animations, just using this shortcut: +> ```swift +> let animation = GradientDirection.leftToRight.slidingAnimation() +> ``` + + + +### 🏄 Transitions + +**SkeletonView** has built-in transitions to **show** or **hide** the skeletons in a *smoother* way 🤙 + +To use the transition, simply add the ```transition``` parameter to your ```showSkeleton()``` or ```hideSkeleton()``` function with the transition time, like this: + +```swift +view.showSkeleton(transition: .crossDissolve(0.25)) //Show skeleton cross dissolve transition with 0.25 seconds fade time +view.hideSkeleton(transition: .crossDissolve(0.25)) //Hide skeleton cross dissolve transition with 0.25 seconds fade time + +``` + +The default value is `crossDissolve(0.25)` + +**Preview** + + + + + + + + + + +

+ + +## ✨ Miscellaneous + + + +**Hierarchy** + +Since ```SkeletonView``` is recursive, and we want skeleton to be very efficient, we want to stop recursion as soon as possible. For this reason, you must set the container view as `Skeletonable`, because Skeleton will stop looking for `skeletonable` subviews as soon as a view is not Skeletonable, breaking then the recursion. + +Because an image is worth a thousand words: + +In this example we have a `UIViewController` with a `ContainerView` and a `UITableView`. When the view is ready, we show the skeleton using this method: +``` +view.showSkeleton() +``` + +> ```isSkeletonable```= ☠️ + +| Configuration | Result| +|:-------:|:-------:| +| | | +| | | +| | | +|| | +| | | +| | | + + + +**Hierarchy in collections** + +Here is an illustration that shows how you should specify which elements are skeletonables when you are using an `UITableView`: + + + +As you can see, we have to make skeletonable the tableview, the cell and the UI elements, but we don't need to set as skeletonable the `contentView` + + + +**Skeleton views layout** + +Sometimes skeleton layout may not fit your layout because the parent view bounds have changed. ~For example, rotating the device.~ + +You can relayout the skeleton views like so: + +```swift +override func viewDidLayoutSubviews() { + view.layoutSkeletonIfNeeded() +} +``` + +> 📣 **IMPORTANT!** +> +> You shouldn't call this method. From **version 1.8.1** you don't need to call this method, the library does automatically. So, you can use this method **ONLY** in the cases when you need to update the layout of the skeleton manually. + + + + +**Update skeleton** + +You can change the skeleton configuration at any time like its colour, animation, etc. with the following methods: + +```swift +(1) view.updateSkeleton() // Solid +(2) view.updateGradientSkeleton() // Gradient +(3) view.updateAnimatedSkeleton() // Solid animated +(4) view.updateAnimatedGradientSkeleton() // Gradient animated +``` + +**Hiding views when the animation starts** + +Sometimes you wanna hide some view when the animation starts, so there is a quick property that you can use to make this happen: + +```swift +view.isHiddenWhenSkeletonIsActive = true // This works only when isSkeletonable = true +``` + +**Don't modify user interaction when the skeleton is active** + + +By default, the user interaction is disabled for skeletonized items, but if you don't want to modify the user interaction indicator when skeleton is active, you can use the `isUserInteractionDisabledWhenSkeletonIsActive` property: + +```swift +view.isUserInteractionDisabledWhenSkeletonIsActive = false // The view will be active when the skeleton will be active. +``` + +**Delayed show skeleton** + +You can delay the presentation of the skeleton if the views update quickly. + +```swift +func showSkeleton(usingColor: UIColor, + animated: Bool, + delay: TimeInterval, + transition: SkeletonTransitionStyle) +``` + +```swift +func showGradientSkeleton(usingGradient: SkeletonGradient, + animated: Bool, + delay: TimeInterval, + transition: SkeletonTransitionStyle) +``` + +**Debug** + +To facilitate the debug tasks when something is not working fine. **`SkeletonView`** has some new tools. + +First, `UIView` has available a new property with his skeleton info: +```swift +var skeletonDescription: String + +``` +The skeleton representation looks like this: + +![](Assets/debug_description.png) + +Besides, you can activate the new **debug mode**. You just add the environment variable `SKELETON_DEBUG` and activate it. + +![](Assets/debug_mode.png) + +Then, when the skeleton appears, you can see the view hierarchy in the Xcode console. + +
