objective c - Full screen UIViewController on iOS 7 -

I have an app that performs well on iOS 8, iPhone 5, but full screen display in iOS 7, iPhone 4. As you can see in the screen shot given below, there is a white strip at the top of the screen. The white strip is present in all my view controllers.

My information. I have the following:

  View Controller-based status bar Attendance: A status bar is initially hidden: Yes  

I have in my View Controller:

  override func prefersStatusBarHidden () - & gt; Bool {Return true}  

Screenshots:

I think you might want to pin the top margin instead of your top barrier set, click on the top.

Remove the margin and pin it at the top of the direct supervision.
