I'm looking for a way to retrieve the UIApplicationLaunchOptionsLocalNotificationKey on iOS that doesn't involve using the application delegate, i.e. I don't want to have to implement the following:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UILocalNotification *localNotification = [launchOptions objectForKey: UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotification != nil)
{
// Process notification
}
}
I'm trying to create a helper library that needs information about the startup notification. Is there anyway of doing this? Can I retrieve the launch options via another method at a later point in the application process?
You can add yourself as an observer of the UIApplicationDidFinishLaunchingNotification notification which will be posed by the application and contains the information you are looking for.
As @Stavash suggests, there are limitations. For the first launch you won't be able to pick this notification up because the instance of your library won't be created (your class would need to be in the root XIB). But, this notification will also be sent when the app is re-opened for local / remote notifications.
