rootViewController isn't working (nil?) on the background

Question

I'm trying to set an object of myViewController called myVC to the window's rootViewController on the AppDelegate like that:

-(void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler
{
    self.myVC=(myViewController*)self.window.rootViewController;
}

It's all working when the app is running but on the background it doesn't working at all.

Anybody knows how can I make it work on the background as well?

Thank you!

What is your rootViewController navigationController or viewController ? — Pushpa Y, Mar 07 '16 at 05:24
Is the methods get executed, try log something inside the method. — Bharat Modi, Mar 07 '16 at 05:31

@BharatModi its get executed when the app is running, how can I know if it's being executed on the background? — FS.O, Mar 07 '16 at 05:35
@BharatModi How can I see the logs when the app is running on the background? — FS.O, Mar 07 '16 at 05:38
The app still pushes log statements to the console if your app is running in the background. If your app is not running but is suspended, there is nothing to log anyway. — Bharat Modi, Mar 07 '16 at 06:01

Try this

EDIT:

AppDelegate.m

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

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"STORYBOARD_NAME" bundle:nil];
ViewController *ViewController = [storyboard instantiateViewControllerWithIdentifier:@"YOUR_IDENTIFIER"];[self.window makeKeyAndVisible];     
[self.window.rootViewController presentViewController:ViewController animated:YES completion:NULL];
return YES;
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
NSLog(@"applicationDidEnterBackground");
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:ADD_YOURCONTROLLER];

[self presentViewController:navController animated:YES completion:nil];
}

Hope this helps.

Try my EDIT and let me know – Kamlesh Shingarakhiya Mar 07 '16 at 05:44
should I use the navigationController although I don't have a navigationController? – FS.O Mar 07 '16 at 05:46
I'll try it when I'll get home and I'll let you know. Thank you! – FS.O Mar 07 '16 at 05:56

Okay so in `applicationDidEnterBackground` method put this `[self.window.rootViewController presentViewController:ViewController animated:YES completion:NULL];` – Kamlesh Shingarakhiya Mar 07 '16 at 05:59
Use application.keyWindow?.rootViewController as? ViewController – Saurabh Saini Nov 22 '20 at 11:58
