I\'ve tried setting the Info.plist \'View controller-based status bar appearance\' to NO, I\'ve tried calling
[[UIApplication sharedApplication] setStatusBar
I think the answer to this question is "This is an iOS 7 bug". None of the methods here helped in our case, and several people have tried to fix this now.
I can't say what steps to reproduce this, but I've seen enough people out there with the same issue, that I think it's safe to say that this is in fact an iOS 7 bug. Most people can fix this problem with the multiple methods listed above. Rarely though, you can't fix it that way. I hope if you are reading this, you are not also one of those people.
