I have a scenario where my UINavigationController is missing the back button (left button) but tapping the left button still seems to work.
I found a similar problem posted here: UINavigationController's back button disappears? which was resolved by not setting the title to @"", but that's not my problem. Are there any other scenarios that would cause this behaviour?
UPDATE:
In case it matters here is my view hierarchy: My MainWindow contains a UINavigationView which first loads a UIViewController (this view contains a Map). When tapping on an annotation accessory button it then loads a UITableViewController. It's this view that should have the back button.
Thanks.
Oh Man! Ok, I found the answer in an article on iphonedevsdk.com, now defunct.
It turns out that my first view (the one with the map on it) didn't have a title set (in fact I hide the navigation bar because I didn't want to show it). Even if the title WAS set on a later view the SDK doesn't seem to care. I still don't understand 100% why I could tap in the area to get it to work.
So even though I hide the first navigation bar I still need to set the title of it.
That did it!
Thanks to everyone who tried to help.
