Crash when launching from push notification with iOS 9

Question

If I launch my app from a push notification the app crash while showing splash screen.

How can I solve this issue?

The crash comes only with iOS9, while everything works with iOS8.

Thanks for the help!

This is my crash log:

Here my code:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    NSDictionary *aps = [userInfo objectForKey:@"aps"];
    NSLog(@"RECEIVE REMOTE NOTIFICATION - APS: %@", aps);

    //Notifica push tipo MATCH_REQUEST
    if ( [[userInfo objectForKey:@"type"] isEqualToString:@"MATCH_REQUEST"] == YES )
    {
        if (application.applicationState == UIApplicationStateInactive)
        {
            NSLog(@"Inactive");
            [self showRequestPushNotification:[aps objectForKey:@"alert"] withDictionary:userInfo];
        }
        else if (application.applicationState == UIApplicationStateBackground)
        {
            NSLog(@"Background");
            [self showRequestPushNotification:[aps objectForKey:@"alert"] withDictionary:userInfo];
        }
        else
        {
            NSLog(@"Active");
            [self showRequestPushNotification:[aps objectForKey:@"alert"] withDictionary:userInfo];
        }
    }

    //Notifica push tipo MATCH_GAME
    else if ( [[userInfo objectForKey:@"type"] isEqualToString:@"NEW_MATCH"] == YES )
    {
        if (application.applicationState == UIApplicationStateInactive)
        {
            NSLog(@"Inactive");
            [self showMatchPushNotification:[aps objectForKey:@"alert"] withDictionary:userInfo];
        }
        else if (application.applicationState == UIApplicationStateBackground)
        {
            NSLog(@"Background");
            [self showMatchPushNotification:[aps objectForKey:@"alert"] withDictionary:userInfo];
        }
        else
        {
            NSLog(@"Active");
            [self showMatchPushNotification:[aps objectForKey:@"alert"] withDictionary:userInfo];
        }
    }
}

SOLVED

The problem is the follows: if I try to show custom notification message while the app isn't in the Active State, the app crash. Before iOS 9 this bug does not appears. So, be careful with the applicationState and check the activeState before manage UIView or UIWindow (graphics objects in general).

How did you manage to get that crash log? Did your app crash in appDidFinishLaunching? – Duodenary

Actually, for me it's not just iOS 9, but iOS 8.4.1 too. – Duodenary

This is the crash log copied from my iPhone device log. If I open my app from an incoming push notification before iOS 9 everything works. I see this problem only with iOS 9. I think that the app crash in appDidFinishLaunching. I also tried to comment all push notification code from appDidFinishLaunching but nothing change... – Affiant

Can you paste your code in func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) { – Duodenary

This happens on my app as well, when some users on production respond to a local notification using an action button. – Cradle
