Question

I use storyboard.
I had a UINavigationContrller as a Initial View Controller. it had a rootViewController relationship with a UIViewController.
The UiViewController has a push segues to a TabBarController.
The first relashionship of the TabBarController is to a TableViewController.

i want to add an edit button to the TableViewController.

I tried to use this code: self.navigationItem.rightBarButtonItem = self.editButtonItem;
But this row is just ignored, and the navigation bar don’t show the button.

I write this code too: self.navigationController.navigationBarHidden = NO;
self.navigationcontroller.navigationItem.hidesBackButton = YES;

The first is not ignored (the navigation bar was hidden from the first UIViewController) the second is ignored and the backbutton remain.

Answer 1

Try adding this to your view controller:

// When this view appears, add show the navigation bar and the edit button
- (void)viewDidAppear {
    [super viewDidLoad];
    self.navigationController.navigationBarHidden = NO; 
    self.navigationItem.hidesBackButton = YES;
    self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

// When this view disappears, remove the editButton and hide the navigation bar
- (void)viewDidDisappear {
    self.navigationItem.rightBarButtonItem = nil;
    self.navigationController.navigationBarHidden = YES;
}
