The app's keyWindow loses its entire view hierarchy once the presented view controller is dismissed, when using the custom view controller transitions API.

I was facing the same issue and there's no need for a workaround. This comment explains what's happening https://stackoverflow.com/a/25901154/3641812 I got it working.

How to use the Workaround

@permakittens where should we use that line? When the transition is cancelled? In the AppDelegate?

I've been meaning to check to see if this was resolved in Beta-7 but don't have that version on this laptop and have slow wifi atm. @kaustubh workaround I've found while Googling answer is to add the subview back to the window:


Note that if you're doing an interactive transition, and the transition was cancelled it would be fromView that you add.

Spoke too soon

Still seems to be a problem in Beta-7 in some situations :(
