Again the Unbalanced calls to begin/end appearance transitions

Question

I know the question has already been asked and answered but I cant find the solution.

I've got this error even if I'm not pushing the incriminated view controller :

Unbalanced calls to begin/end appearance transitions for .

here is my code NewsViewController.m

I think my problem may be due to my implementation of the init - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil tableauDeNews:(NSMutableArray *)tableauDeNews;

need help thx

Answer 1

I found the problem:

To create my buttons I copy paste them in the interfaceBuilder, the copied buttons have kept their old actions, and I had a new IBAction.

My copied buttons had 2 IBactions (one calling a NewsViewController and another calling the right viewController). The message was poping each time I clicked the copied button.

So check your buttons in the interface Builder, "Unbalanced calls to begin/end appearance transitions" can be caused by buttons having two IBActions, conflictual (eg. pushing two different viewControllers at the same time).
