Segue forcing UITabBarController to move status bar in Swift?

Question

I have a weird problem regarding how I limit the screen orientation.

Here's what my storyboard looks like:

My screen orientation is set to Portrait only.

In my AppDelegate app, I have the following:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask { if self.window?.rootViewController?.presentedViewController is VideoPlayerViewController { return UIInterfaceOrientationMask.Landscape; } else { return UIInterfaceOrientationMask.Portrait; } } 

On the "Home" tab, clicking the "Red" button or any of the cells, you will go to my VideoPlayerViewController . I limited VideoPlayerViewController to terrain only.

However, right before segue happens, this happens:

Basically, what happens is that in the second image the red part moves upward, pushing the status bar to the side.

Then, in the 3rd picture, the first 2 tabs are slightly shifted to the left , while the last 2 tabs are slightly shifted to the right .

Again, all this happens just before the Modal transition occurs.

What could be the reason for this? Let me know if I need to add additional code.

Answer 1

In an attempt to remove as much irrelevant code as possible in order to publish the sample code on github for others to help debug, I found the culprit of my problem.

It is associated with override func prefersStatusBarHidden() in my code, causing the status bar to shift and is now allowed.
