Strange ellipsis appearing in UINavigationBar

Question

I have implemented a navigation item with a left button, a title view, and a right button. The back button is set to "hides".

On some left transitions, a blue ellipsis appears momentarily.

Any ideas as to what this is and how to get rid of it?

Answer 1

I fixed this by not calling:

self.navigationItem.hidesBackButton = YES;

By setting a custom left bar button item, but not calling that method/setting it to NO, the ellipsis doesn't appear. I assume this is an Apple bug.
