Objective-c – Custom back button view

iphoneobjective c

I'm trying to change the back button to a custom one. If I create a UIBarButtonItem with just a custom title, that works fine. However if I create one with a custom view, the button doesn't show, rather the default back button shows. Any ideas ?

UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom];
backBtn.frame = CGRectMake(0, 0, 51, 31);
[backBtn setImage:[UIImage imageNamed:@"nav_btn_back.png"] forState:UIControlStateNormal];
[backBtn addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *back = [[[UIBarButtonItem alloc] initWithCustomView:backBtn] autorelease];
self.navigationItem.backBarButtonItem = back;

Not sure why that's not working. However I realized that I can just set this custom button as a leftBarButtonItem for my view

I used the following psd that I derived from http://www.teehanlax.com/blog/?p=447

I then just created a custom UIView that I use in the customView property of the toolbar item.

Works well for me.

Edit: As pointed out by PrairieHippo, maralbjo found that using the following, simple code did the trick (requires custom image in bundle) should be combined with this answer. So here is additional code:

// Creates a back button instead of default behaviour (displaying title of previous screen)
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"back_arrow.png"]
                                                               style:UIBarButtonItemStyleBordered
                                                              target:self
                                                              action:@selector(backAction)];

tipsDetailViewController.navigationItem.leftBarButtonItem = backButton;
[backButton release];

Ios – UINavigationController “back button” custom text

From this link:

self.navigationItem.backBarButtonItem =
   [[UIBarButtonItem alloc] initWithTitle:@"Custom Title"
            style:UIBarButtonItemStylePlain
           target:nil
           action:nil];

As Tyler said in the comments:

don't do this in the visible view controller, but in the view controller that you'd see if you hit the back button
