Answer 1

Is your application in the background or foreground? If it's in the foreground, I'm pretty sure that method is called. If it isn't, maybe you aren't putting that method in your application delegate.

If it's on the background, here's a few possible scenarios:

1. Your app has been killed by the user or the OS. In this case when the user wake up your app by tapping on the notification on the notification centre (or swiping in lock screen), your application delegate will have the application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method called. You can get the notification from this method by:

   [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

2. Your app is in background, and the user tap on the notification in notification centre or lock screen. In this case, no delegate methods will be called. The documentation specifically said that didReceiveLocalNotification: is for when the app is in the foreground:

If the app is running in the foreground, there is no alert, badging, or sound; instead, the application:didReceiveLocalNotification: method is called if the delegate implements it.

So hopefully you can make an informed decision about what to do when you receive the notification. I personally find it a little bit weird that we don't get the notification object when the user launches the app by tapping the icon (not the notification). But I currently just write my logic around it.
