How to add an overlay to a UITabbarController

Question

Hi I have a UITabBarController which i want to add on top an overlay containing a registration form. I've seen several places that the way to go is to use this command:

[[[UIApplication sharedApplication] keyWindow] addSubview:registrationView];

But How can I create registrationView from the storyboard and be able to access it from the UITabBarController ?

Note: My registrationView should hide the tabs so i can't put it in one tab.

Hey this will solve you issue

UITabBarController *tabBarController = (UITabBarController *) self.window.rootViewController;

 ViewController *RegistrationView = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
 [tabBarController presentModalViewController:RegistrationView animated:YES];

 [tabBarController.selectedViewController viewDidAppear:true];

do this in - (void)applicationDidBecomeActive:(UIApplication *)application function
