Warning while dismissing and presenting FullScreen ModalViewController

Question

I have SplitViewController project. In the detail's pane (right side), in the method -viewDidAppear, I have this code:

login.modalPresentationStyle = UIModalPresentationFullScreen;
login.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

In the "login" ViewController I have a button that when is clicked, goes to this method:

-(void)registerEvent{
NSLog(@"registerEvent");
[self dismissViewControllerAnimated:YES completion:^{
[_delegate dismissLogin];
}];
}

And in my delegate ViewController (the detailViewController) method, I have this code:

-(void)dismissLogin{
ViewControllerRegister * registerForm = [ViewControllerRegister new];
[registerForm setDelegate:self];

registerForm.modalPresentationStyle = UIModalPresentationFullScreen;

registerForm.modalTransitionStyle = transition;

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

The problem is, if I change the modal presentation style to UIModalPresentationFormSheet, the compiler gives me NO warning and the registerForm ViewController is presented. But with UIModalPresentationFullScreen, the compiler gives me this warning:

Warning: Attempt to present on while a presentation is in progress!

I have already tried to use performSelector with a delay of 0.4 and still not solve the problem.

How can I solve this?

Thanks

I believe this means that your view is already presenting something and it cannot present another view on the top of it.
