Usage

1. Check the demo in JSPopoverMenuDemo. The demo is designed to show the menu view when the titleView, which is a UIButton, of the NavigationBar is tapped.
2. JSPopoverMenuViewDelegate protocal is required to implement.
3. JSPopoverMenuView is a subclass of UIView, so just use it like others.

1. Initialization

The default width is the same as the screen. Simply use a String array to initialize, every single String represents a tag (a Cell) on the collection view.

popoverView = JSPopoverMenuView(tags: ["Sports", "Movies", "Food", "News", "Travel", "Books"]) 

If you use any data model to manage tags, make your model confirm JSTag protocols and use the following initializer.

let data: [JSTag] = ["Sports", "Movies", "Food", "News", "Travel", "Books"].enumerated().map(){ JSDefaultTag(id: $0, title: $1) })
popoverView = JSPopoverMenuView(data: data) 

Check section 4 for more information.

2. Delegate

1. Set delegate

popoverView.delegate = self 

self refers to a view controller in the demo. Any subclass of UIView is also fine.

2. Set baseView. The entire PopoverView will be added to the baseView

 var baseView: UIView { return self.view } 

3.1 Tag Tapped Event

func popoverMenu(_ popoverMenu: PopoverMenuView, didSelectedAt indexPath: IndexPath) 

3.2 Edit Done Event

func popoverMenu(_ popoverMenu: PopoverMenuView, updatedData data: [JSTag])

3.3 New Tag Inserted Event

func popoverMenu(_ popoverMenu: PopoverMenuView, newTag value: JSTag)

Notice: This function will be invoked right after users added a new tag, which means the menu is still under the editing mode and the new tag could be delete immediately. Thus, it's better to get the final data after the editing b func popoverMenu(_ popoverMenu: PopoverMenuView, updatedData data: [JSTag]).

3. Show

There are two methods to show and dimiss the menu.
1. QuickSwitch.
Show the menu if the menu is not displayed, or dimiss it if the menu is displayed

    popoverView.quickSwitch()

2.1 Show

    popoverView.show() { print("I'm here") } 

2.2 Dimiss

    popoverView.dismiss() { print("See ya") } 

4. Data source type

A tag basically is a string, but an id is requried to make it unique.
So, the PopoverMenu use a simple protocol to constraint the data model.

protocol JSTag {
    var title: String { get set }
    var id: Int { get set }
}

By default, PopoverMenu use JSDefaultTag as data source type. However, if id means nothing to you, you can use the following initialization method to create an instance.

popoverView = JSPopoverMenuView(tags: ["Sports", "Movies", "Food", "News", "Travel", "Books"])

5. UI Customization

The height of PopoverView can be set via initilizer or frame property since the PopoverView itself is subclass of UIView.

/// Gap between header and the tag collection.
public var menuTopOffset: CGFloat = 5
/// Height of tag collection view.
public var menuHeight: CGFloat = 115
/// Height of the header tool bar.
public var headerHeight: CGFloat = 30
