use this line [[self navigationItem] setLeftBarButtonItem:random1]; — Sudha Tiwari, Feb 05 '13 at 12:43
by the way, from Apples Documentation [[ - (id)initWithRootViewController:(UIViewController *)rootViewController ((rootViewController)) The view controller that resides at the bottom of the navigation stack. This object cannot be an instance of the UITabBarController class. ]] Look at this linnk : http://developer.apple.com/library/ios/#documentation/uikit/reference/UINavigationController_Class/Reference/Reference.html — Shumais Ul Haq, Feb 05 '13 at 13:31

I see nothing wrong with your code just check your image or try with a rounded rect image to test

UIButton* button4 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button4 setFrame:CGRectMake(0.0f, 0.0f, 25.0f, 25.0f)];
[button4 addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *random1 = [[UIBarButtonItem alloc] initWithCustomView:button4];

and use self.navigationController.navigationBar.topItem.leftBarButtonItem=random1; instead of self.navigationController.navigationItem.leftBarButtonItem=random1;

The problem is in the following line :

self.navigationController.navigationItem.leftBarButtonItem=random1;

Simply use

self.navigationItem.leftBarButtonItem=random1;

If your app has more than a single navigation bar, then are you sure that the correct navigation bar is visible? – Shumais Ul Haq Feb 05 '13 at 13:01
