如何从导航栏中删除后退按钮

Question

I have that code. It can add edit button to navigatin bar, but back button still exists, but it becomes unresponsible.

UIBarButtonItem *editButton = [[UIBarButtonItem alloc] 
                               initWithTitle:@"Edit"                                            
                               style:UIBarButtonItemStyleBordered 
                               target:nil 
                               action:nil];
[[self.navigationController.navigationBar.items objectAtIndex:1] setRightBarButtonItem:editButton];

[[self.navigationController.navigationBar.items objectAtIndex:1]setHidesBackButton:YES];

Answer 1

simply and short:

  self.navigationItem.backBarButtonItem = nil;

or

  self.navigationItem.leftBarButtonItem = nil;

Answer 2

I have done something similar to this before. In the controller that's going to push the next view controller that you don't want a back button in put this wherever you're doing your pushViewController:

 myNextViewController.navigationItem.hidesBackButton = YES;
 [self.navigationController pushViewController:myNextViewController animated:YES];

Answer 3

You can also use

Objective-C:

self.navigationItem.hidesBackButton = YES;

Swift:

navigationItem.hidesBackButton = true

Answer 4

Either of these will work

self.navigationItem.leftBarButtonItem = nil;

or

self.navigationItem.backBarButtonItem = nil;

Answer 5

This is old but after reading this today the answer of:

self.navigationItem.hidesBackButton = YES;

is correct but is incomplete, this needs to be done at a later life cycle method then viewDidLoad, aka toss it in viewWillApper or something later and it will work

- (void)viewWillAppear:(BOOL)animated{
    self.navigationItem.hidesBackButton = YES;
}

Hope this helps someone looking at an old post as I did today
