Add this in viewDidLoad method of this viewController and customise it like you want

 UIImage *backButtonImage = [UIImage imageNamed:@"Back_A.png"];
UIImage *backButtonImage1 = [UIImage imageNamed:@"Back_B.png"];

UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];

[backButton setImage:backButtonImage
            forState:UIControlStateNormal];

[backButton setImage:backButtonImage1
            forState:UIControlStateSelected];

[backButton setImage:backButtonImage1
            forState:UIControlStateHighlighted];

backButton.frame = CGRectMake(0, 0, 55, 45);

[backButton addTarget:self
               action:@selector(goBack)
     forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.rightBarButtonItem = backBarButtonItem;

With frame you can show the button where you want.
