Can any one tell me which control is this ? Or any tutorial for it ?

Solution

  • Check out the MoveMe sample app. It will show you how to allow movement of subviews by touch and drag.

    You can then create imageViews for each of your puzzle pieces that can be moved around.

    Once you have accomplished this you need to check during movement of a piece to see when it gets close enough to it's correct spot in the puzzle so it can snap into place when then user lets go of the piece.
