You don't need to develop purchase screens. So easy!

SDK Requirements

Panda SDK requires minimum iOS 11.2, Xcode 10 and Swift 4.2.

Installation

Panda SDK can be installed via CocoaPods, Swift Package Manager or manually.

Install via CocoaPods

Add the following line to your Podfile:

pod 'PandaSDK'

And then run in the Terminal:

pod install

Install via Carthage

To use PandaSDK with Carthage, add it in your Cartfile.

github "github "AppSci/PandaSDK"

Install via SPM (Swift Package Manager)

Add dependecy with the following URL:

https://github.com/AppSci/PandaSDK

Manual Installation

Copy all files in Source folder to your project.

Initialize Panda SDK

To set up Panda SDK you will need API Key. Register your app in Panda Web and get your API key.

import PandaSDK

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
	
  Panda.configure(token: "YOUR_API_KEY", isDebug: true) { (result) in
      print("Configured: \(result)")
  }

  // the rest of your code
  return true
}

Working with Screens from Panda

For getting screen from Panda Web you should use

func getScreen(screenId: String?, callback: ((Result<UIViewController, Error>) -> Void)?)

If you wanna prefetch screen to ensure that it will be ready before displaying it, you can use

func prefetchScreen(screenId: String?)

We recommend you prefetch screen right after Panda SDK is configured:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    Panda.configure(token: YOUR_SDK_TOKEN, isDebug: true) { (result) in
        print("Configured: \(result)")
        if configured {
            Panda.shared.prefetchScreen(screenId: YOUR_SCREEN_ID)
        }
    }
    return true
}

You can use Default screen in case of any errors - e.g. no inet connection - if you want, you can embed "PandaSDK-Default.html" screen in bundle - name is critical - it should be named exactly "PandaSDK-Default.html" - we will use it for displaying this screen in case of any errors

Plist structure

To have all set, you need to add this info in your PandaSDK-Info.plist - you can create it by your own or download PandaSDK-Info.plist from Example - structure of PandaSDK-Info.plist is crutial, please, add

Plist property	value
BILLING_URL	https://apps.apple.com/account/billing	add your URL for Billing page or leave it as it is
POLICY_URL	https://policy.com	add your URL for Policy & Privacy page
TERMS_URL	https://terms.html	add your URL for Terms & Conditions page
SERVER_URL	https://sdk-api.panda.boosters.company	URL of Panda Server - please, do not remove
productIds	Array	Array of your Purchase product ids

Handle Subscriptions

Panda SDK provides a set of methods to manage subscriptions.

Fetch Products

Panda SDK automatically fetches SKProduct objects upon launch. Products identifiers must be added in "PandaSDK-Info.plist". You can download example for .plist from Example app in Source code.

Make a Purchase

To make a purchase - you are creating html with products_ids for Purchases - Panda SDK upon clicking on concreate button or view gets this product_id for purchase & you just need to implement callbacks for successful purchase or error :

var onPurchase: ((String) -> Void)? { get set }
var onError: ((Error) -> Void)? { get set }

Restore Purchases

Restore Purchase is called when user tap on Restore purchase button on html screen. You can handle this restore by implementing this callback Returns product_id for Restore Purchase

var onRestorePurchase: ((String) -> Void)? { get set }

Basically it just sends App Store Receipt to AppStore .

Skipping Purchase Process

You can allow your users to skip all purchase process - when user tap cross on Screen, you can allow user to go futher into your app - this callback is called

var onDismiss: (() -> Void)? { get set }

Push Notification Support

You can add push motification support from Panda - so your app will react on Apple Subscription Events - e.g. User can recieve notification in case on Subscription Cancellation

To register User for Push notification add this in your AppDelegate

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    Panda.shared.registerDevice(token: deviceToken)
}

Than add this line in your UNUserNotificationCenterDelegate:

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    if Panda.shared.userNotificationCenter(center, willPresent: notification, withCompletionHandler: completionHandler) {
        return
    }
    completionHandler([])
}


func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    if Panda.shared.userNotificationCenter(center, didReceive: response, withCompletionHandler: completionHandler) {
        return
    }
    completionHandler()
}
