with this am getting warning : : CGImageCreateWithImageProvider: invalid image size: 0 x 0.

(void)viewWillAppear:(BOOL)animated
 {
    UIImage *backButtonHomeImage = [[UIImage imageNamed:@"back-arrow.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 104, 13)];
    [[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonHomeImage  forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

    self.navigationItem.leftBarButtonItem = nil;
}

            [backButton setShowsTouchWhenHighlighted:TRUE];
            [backButton addTarget:self action:@selector(popViewControllerWithAnimation) forControlEvents:UIControlEventTouchDown];
            UIBarButtonItem *barBackItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
            self.navigationItem.hidesBackButton = TRUE;
            self.navigationItem.leftBarButtonItem = barBackItem;
        }

Answer 3

Create custom back button and add that button to Navigation controller's back button.

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 
button.frame = CGRectMake(0,0,54,32);
UIImage *backButtonImage = [UIImage imageNamed:@"back-arrow.png"];
[button setBackgroundImage:backButtonImage forState:UIControlStateNormal];
[button addTarget:self.navigationController action:@selector(popViewControllerAnimated:) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
[self.navigationItem setLeftBarButtonItem:barButtonItem];

Answer 4

Just set blank text to title of navigation bar before pushing to that view Controller as below code.

self.navigationItem.title=@" ";

Answer 5

I hope this would work

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