Navigation Back Button does not show,how to add back button to UINavigationItem

Question

I add UINavigationBar via Library to view. I also add UINavigationItem to this NavigationBar.

In viewController.m,I added the following code but back button doesn't show.

self.navigationItem.title = @"List";
self.navigationItem.backBarButtonItem.title = @"Back";

Answer 1

Try this:

self.navigationItem.leftItemsSupplementBackButton = YES;

or

navigationItem.leftItemsSupplementBackButton = true

If you customize your navigation controller with UIBarButtonItems the framework removes the back button by default, since it assumes you are customizing the Navigation bar. Use that line to add the back button in again.
