Unbalanced calls to begin/end appearance transitions for

Question

I read SO about another user encountering similar error, but this error is in different case.

I received this message when I added a View Controller initially:

Answer 1

I had lot of problem with the same issue. I solved this one by

1. Initiating the ViewController using the storyboad instantiateViewControllerWithIdentifier method. i.e Intro *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"introVC"];
2. [self.tabBarController presentModalViewController : vc animated:YES];

I have the viewcontroller in my storyboard, for some reason using only [[introvc alloc] init]; did not work for me.
