We recently ran into a weird issue with UIAlertView. The UIAlertView is being used for updating the progress of an upload. We made sure that updating our UIProgressView was happening on the main thread, and then added:
[alertView setTitle:@”New Title”]
For some reason, the progress was changing, but no new title.
Then someone found a different call that was happening from a background thread. Rather than just failing, it was actually making it so that all future calls to setTitle would fail.
