Warning: Attempt to present <MyViewController: 0x10c5771a0> on <UINavigationController: 0x10c533da0> whose view is not in the window hierarchy

I am trying to segue to my ViewController with this code:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"iPhone_Storyboard" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"details"];
[self presentViewController:vc animated:YES completion:nil];

However I get this error message:

Warning: Attempt to present <MyViewController: 0x10c5771a0> on <UINavigationController: 0x10c533da0> whose view is not in the window hierarchy!

I am calling the segue in the UIAlertView Delegate Method:

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{

}

Your UIAlertView's window is the frontmost UIWindow, so your view controller can't present. You need to wait until the alert view dismisses. The simplest way is to use alertView:didDismissWithButtonIndex: (instead of clickedButtonAtIndrx).

add this too, it worked for me.

lvc.modalPresentationStyle = UIModalPresentationFormSheet;
lvc.modalTransitionStyle = UIModalTransitionStyleCoverVertical;

[mvc presentModalViewController:lvc animated:YES];
