How can I remove dafult button to place my custom button in navbar? Problem at the moment is that my custom button is over default button. 
Please take a look at the screenshot and it will be more clear.
I’m getting this with following code:
- (void)viewDidLoad
{
UIImage *menuImage = [UIImage imageNamed:@"barMenuButton.png"];
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithImage:menuImage style:UIBarButtonItemStylePlain target:self action:@selector(ShowLeftMenu:)];
[self.navigationItem setRightBarButtonItem:addButton];
}
This will fix your problem:
