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;

please check that your navigation bar is provided hidden property and try with default back button once & let us know is it working or not.

UIBarButtonItem *barBtnItem = [[UIBarButtonItem alloc] initWithTitle:@"back" style:UIBarButtonItemStyleBordered target:self action:@selector(nextToPhoneAuth)];
self.navigationItem.backBarButtonItem = barBtnItem

UIButton *button4 =  [UIButton buttonWithType:UIButtonTypeCustom];
[button4 setImage:[UIImage imageNamed:@"del.png"] forState:UIControlStateNormal];
[button4 addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
[button4 setFrame:CGRectMake(0.0f, 0.0f, 25.0f, 25.0f)]];
    self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:button4] autorelease];

The problem is in the following line :

self.navigationController.navigationItem.leftBarButtonItem=random1;

Simply use

self.navigationItem.leftBarButtonItem=random1;
