ios - iOS 8 - Unable to make the UIModalPresentationFormSheet transparent

Question

In iOS 7, I have a piece of code that works similar to requirements mentioned in

1. How do I make the flip animation on a modal view on the iPad transparent in the background?

and

2. Seamlessly flip from one modal view to another, without showing a solid colour background

and the way I implemented it in iOS 7 is by using the methods mentioned in this question UIModalPresentationFormSheet can't change superview background to clear

so far working well until Apple released iOS 8. In iOS 8 modController.view.superView is returning nil, which greatly affects my animation by showing a gray background. It'll be a great help if anyone has a idea on how to fix this issue. Thanks in advance.
