IPhone App: implementation of Drag and drop images in UIView?

Try below link drag and drop image around the screen.

Easiest way is to use a UIPanGestureRecognizer. That will give you messages when the view is moved and when it is dropped. When it is moved, update its center.

When it is dropped, check if its position is within the bounds of the view you want to drop in. (You might need to convert coordinates to the target view's coordinate system.) If it is, do the appropriate action.

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.
