Back button is not visible in iOS 7

Question

I have some weird trouble about iOS 7. I have an UINavigationBar in my app and it works perfect for iOS 6;

Answer 1

Setting BackButtonBackgroundImage via UIAppearance currently has some odd behavior in iOS 7. This is probably related to the updated design, which replaces the rect-style button with a backIndicatorImage (an arrow).

This leaves 3 options for customizing the back button's appearance:

1. Change the color of the backIndicatorImage by setting the tintColor property on UINavigationBar (or one of its superclasses).

2. Set the new backIndicatorImage property on UINavigationBar to a custom image. (don't forget to set the backIndicatorTransitionMaskImage as well or it won't work)

3. Create a custom UIBarButtonItem and manually assign it as UINavigationItem's leftBarButtonItem. (See the answer mentioned above by Mashhadi)
