Invisible back button when view controller pushed onto navigation controller

Question

I'm using a navigation controller to drill into a detail view when a cell is tapped. When I push my view controller onto the navigation controllers stack, I expect to see a back button that I can tap to pop the previous view off the stack.

The issue is that the back button isn't visible, but when tapping where it should be returns me to the previous view. What's the problem?

Answer 1

Ensure you have set a title for the master view - for example in viewDidLoad add this -

self.title = @"The Title";

Weirdly, if there is no title for the parent view controller on the stack, rather than show an empty back button, the iPhone will not display a button but will allow taps on the area where it should be.

This bugged me for a long time!
