Klarna Mobile SDK demo app for iOS

KlarnaMobileSDK Demo

This demo shows how you can integrate KlarnaMobileSDK into your existing web views, UIWebView or WKWebView.

It loads a local harry.html file into webviews for demonstrations.

Run the demo app

This demo demonstrate how you can use Cocoapods to integrate KlarnaMobileSDK into your XCode project, this is included Podfile:

use_frameworks!

platform :ios, "10.0"

target "KlarnaMobileSDKDemo" do
   pod "KlarnaMobileSDK"
end

To run the demo app, just open KlarnaMobileSDKDemo.xcworkspace, click on Run.

Important steps during integration

There are a few important steps that you need to perform to have a successful integration:

• Initialize KlarnaHybridSDK with a UIWebView or WKWebView, make sure providing a returnUrl and eventListener during the initialization.

	klarnaHybridSDK = KlarnaHybridSDK(webView: webView,
                                   returnUrl: URL(string: "your-app-scheme://")!,
                                   eventListener: self)

• Implement WebView's delegate, call relavant KlarnaHybridSDK methods.

  • For UIWebView:

     func webViewDidFinishLoad(_ webView: UIWebView) {
         klarnaHybridSDK?.newPageWillLoad(in: webView)
     }
    
     func webView(_ webView: UIWebView,
                  shouldStartLoadWith request: URLRequest,
                  navigationType: UIWebView.NavigationType) -> Bool {
    
         return klarnaHybridSDK?.shouldFollowNavigation(withRequest: request) == true ? true : false
     }

  • For WKWebView:

     func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
         klarnaHybridSDK?.newPageWillLoad(in: webView)
     }
    
     func webView(_ webView: WKWebView,
                  decidePolicyFor navigationAction: WKNavigationAction,
                  decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
    
         decisionHandler(klarnaHybridSDK?.shouldFollowNavigation(withRequest: navigationAction.request) == true ? .allow : .cancel)
     }

• Implement KlarnaHybridSDKEventListener.

    func klarnaHybridSDKWillShowFullscreen(inWebView webView: KlarnaWebView, completion: () -> Void) {
        // Handle fullscreen transitions
        print("[KlarnaHybridSDK]: will show fullscreen")
        completion()
    }

    func klarnaHybridSDKDidShowFullscreen(inWebView webView: KlarnaWebView, completion: () -> Void) {
        // Handle fullscreen transitions
        print("[KlarnaHybridSDK]: did show fullscreen")
        completion()
    }

    func klarnaHybridSDKWillHideFullscreen(inWebView webView: KlarnaWebView, completion: () -> Void) {
        // Handle fullscreen transitions
        print("[KlarnaHybridSDK]: will hide fullscreen")
        completion()
    }

    func klarnaHybridSDKDidHideFullscreen(inWebView webView: KlarnaWebView, completion: () -> Void) {
        // Handle fullscreen transitions
        print("[KlarnaHybridSDK]: did hide fullscreen")
        completion()
    }

    func klarnaHybridSDKFailed(inWebView webView: KlarnaWebView, withError error: KlarnaMobileSDKError) {
        // Handle Klarna hybrid SDK related errors
        print("[KlarnaHybridSDK]: did get error: \(error.debugDescription)")
    }
