Launch App using URL, but OpenUrl Not Called

Question

I have implemented a URL Scheme and use it to pass data to my app by calling method. The entire code is shown as below

- (BOOL)application:(UIApplication *)a         


        

Answer 1

I landed up with the same issue for an app on iOS 13. Even with the proper implementation of - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options method, it never got invoked.

From iOS13, the SceneDelegates get invoked instead of the AppDelegate method. Once I implemented the

- (void)scene:(UIScene *)scene openURLContexts:(NSSet *)URLContexts

on the scene delegate, it would work if the app was already in memory. However, for a cold start, I had to implement the call back

-(void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions

as well.
While implementing

-(void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions

please remember to handle cases when the app is not launched from an URL.
