Question

I have an app using storyboard. The layout is: Nav Controller > Login View Controller > Tab Bar Controller and each tab has a Nav Controller pointing to the UIViewController for that tab. I’m trying to create a log out button that would remove the TabBarController and go back to the Login View Controller. My code is as per below:

// In log out function
[self.tabBarController dismissViewControllerAnimated:YES completion:nil];
[self performSelector:@selector(patchSelector) withObject:nil afterDelay:0.3];

-(void)patchSelector{
    [self.tabBarController.navigationController popToRootViewControllerAnimated:YES];
}

I keep getting the following error:

*** Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'presentedViewController for controller is itself on dismiss for

I tried reading the following regarding this:

No visible interface for dismissModalViewControllerAnimated:completion

UITabbarController dismiss modal UINavigationController

However, none of the above helped with the error i’m getting. Is there something i’m missing in this? The error seems to indicate that the current vc is among those getting cleaned up.

Answer 1

When I remove my very first UINavigationController (the one before login screen) and I change the first line above to this: [self dismissModalViewControllerAnimated:YES];, it works…but only if I make it a modal segue. Easiest solution. Not sure why my original issue was, but i was able to get around it this way atleast!
