Drag-n-Drop from UIPopoverController to other UIView?

You have to deal with two view controllers one that's in the background called mainController one that presented using a UIPopoverViewController called popoverController. Your popoverController could add a UIPanGestureRecognizer to the views, that the user can drag. The action target of the gestureRecognizer could be a method on the popoverController.

According to the documentation on UIPopoverController, when the popover is presented, it is presented on a special "window". Because of this, simply adding a subview to the popover view controller's content view controller is not sufficient to be able to drag a view outside of the popover view controller's 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.
