Call touches anyObject locationInView: self. Superview to get the point under the finger in the container view. Then send self.
Superview -hitTest:withEvent: to find out the view X is inside. Note that it will always return X, so you will have to override either -pointIsInside:withEvent: or -hitTest:withEvent: to return nil while you're dragging. This kind of kludge is the reason I would implement such tracking in the container view, rather than in a dragged view.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
