http://stackoverflow.com/questions/6965795/uiview-popup-like-uialertview Animate the view's transform using UIView animation using blocks or older api from some really small size like view.transform CGAffineTransformMakeScale 0.1 0.1 to something a little bigger then you want it to be like view.transform CGAffineTransformMakeScale.. size like view.transform CGAffineTransformMakeScale 0.1 0.1 to something a little bigger then you want it to be like view.transform CGAffineTransformMakeScale 1.1 1.1 then back to the desired size view.transform CGAffineTransformMakeScale 0.1 0.1 or add.. bigger then you want it to be like view.transform CGAffineTransformMakeScale 1.1 1.1 then back to the desired size view.transform CGAffineTransformMakeScale 0.1 0.1 or add more steps for bigger bounce. And for moving it around implement the touch methods..
