How to use handleOpenURL alerts for UIApplication

Question

I am trying to process UIApplication notifications to get URL Schemas in the current open view. I tried several notifications, but I don’t know which object contains URL schemes.

NSNotificationCenter *nc = [NSNotificationCenter defaultCenter]; //[nc addObserver:self selector:@selector(DocumentToDropboxDelegate) name:UIApplicationWillResignActiveNotification object:nil]; [nc addObserver:self selector:@selector(DocumentToDropboxDelegate) name:UIApplicationDidFinishLaunchingNotification object:nil]; 

Someone can help me with this problem.

Answer 1

As mentioned in @Mike K, you will have to implement one (or both) of the following methods:

 - application:handleOpenURL: - application:openURL:sourceApplication:annotation: 

in your UIApplicationDelegate. There is no corresponding notice for them.

Example below:

 -(BOOL) application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { if (url != nil && [url isFileURL]) { [self.viewController handleOpenURL:url]; } return YES; } //Deprecated -(BOOL) application:(UIApplication *)application handleOpenURL:(NSURL *)url { if (url != nil && [url isFileURL]) { [self.viewController handleOpenURL:url]; } return YES; } 

Answer 2

application:handleOpenURL: called by your application delegate - not through NSNotification. preferred delegation method to implement: application:openURL:sourceApplication:annotation:
