UIModalTransitionStylePartialCurl disappear on iOS

问题:

I am trying to present my ViewController with UIModalTransitionStylePartialCurl transition. I am using the following code

PuzzleViewController *vc = [[PuzzleViewController alloc] init];
vc.modalTransitionStyle = UIModalTransitionStylePartialCurl;
vc.puzzleImage = imageView.image;
[self.navigationController presentViewController:vc animated:YES completion:nil];

UIModalTransitionStylePartialCurl work fine with iOS 7, like this

But for iOS 8, the visual part of the previous view on top disappear, so the user can't understand that he can click on the top left corner to back to previous view.

So is there a way to fix this on iOS 8?

This is broken in iOS 8 and Xcode 6. Here is the Radar for it: http://www.openradar.me/18305611
