问题
I have set up a custom deep-linking iOS URL scheme for my app, and I listen for it in
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
I parse the URL and send a notification using NSNotificationCenter, with the URL as the object, to the appropriate class to handle the URL.
This all works great when the app is "backgrounded" but when the app is fully closed out of multitasking, it seems like the notification never gets sent (or received). Am I missing something about the process of notifications when the app isn't in backgrounding? Is there another way to pass along the information from the URL? Or is there at least a way to tell if the app is coming out of backgrounding or if it is a fresh launch?
Thanks!

You should check the launchOptions dictionary that is passed into applicationDidFinishLuanching:withOptions:.
