iOS 7: How to set UIBarButtonItem backButtonBackgroundImage for UIControlStateHighlighted?

Question

I am trying to set the background image for back button in normal and highlighted states.

- (void)configureBackButtonInNavigationItem:(UINavigationItem *)item
{

You didn't want a custom view because it would break the swiping, but you should add this line.

self.navigationController.interactivePopGestureRecognizer.delegate = (id)self; 

Your code would be something like below.

UIImage *normalImage = [[[UIImage imageNamed:@"btn_normal"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] resizableImageWithCapInsets:UIEdgeInsetsMake(0.f, 17.f, 0.f, 0.f)];
UIImage *pressedImage = [[[UIImage imageNamed:@"btn_on_press"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] resizableImageWithCapInsets:UIEdgeInsetsMake(0.f, 17.f, 0.f, 0.f)];    

UIButton *customBackButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customBackButton setBackgroundImage:normalImage forState:UIControlStateNormal];
[customBackButton setBackgroundImage:pressedImage forState:UIControlStateHighlighted];
[customBackButton addTarget:self action:@selector(customBackMethod:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *customBackBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:customBackButton];
self.navigationItem.leftBarButtonItem = customBackBarButtonItem;
self.navigationController.interactivePopGestureRecognizer.delegate = (id)self;

- (IBAction)customBackMethod:(id)sender {
    [self.navigationController popViewControllerAnimated:YES];
}
