    How about the following from the UIView reference

    willMoveToSuperview:, didMoveToSuperview – Implement these methods as needed to track the movement of the current view in your view hierarchy.

    this will at least tell you when it is added to a view hierarchy but there is no guarantee that the view hierarchy is presented/viewable.
