I have a view controller that has the following hierarchy:
UIViewController
|
|-view
|-presentView (UIView)
 
I've been struggling with this issue and the only way I could resolve it is that I put the fromView into another view. In your case the view hierarchy should look like this:
UIViewController | |-view |-containerView |-presentView |-stagedView |-UIToolBar
The fromView parameter still should point to presentView. Hope this helps.
