Again the Unbalanced calls to begin/end appearance transitions - objective-c

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
#import "NewsViewController.h"
#import "XMLToObjectParser.h"
#import "UneNews.h"

#end
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).
