Answer 1

Yes you can find application launching reason in

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

// keys can be UIApplicationLaunchOptionsLocalNotificationKey

NSDictionary *notificationPayload = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
if(notificationPayload)
{
    // application launch because of notification
    // do some stuff here
}

return YES;

}

Answer 2

In - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method of the application delegate, you will receive the notification information in the launchOptions dictionary. That way you could get to know that the app was launched from the notification tray.

Answer 3

You can handle push notification like

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    NSDictionary *pushNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (pushNotification) {
        //Application did started by clicking push notification. Do whatever you want to do
    }

  ....//Your rest code
  ....
}

Some times application is in active state and still we want to handle push notification than below method will be called

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    //Application did receive push notification. Do whatever you want to do
}
