Answer 1

Make them UIButtons and use: [button setImage:forState:] then you can use targets and actions.

Answer 2

take look at touchesBegan,touchesMoved functions

Answer 3

Hello

They are different ways and it depends on how you are currently moving the UIImageView.

1°) If UIImageView are not subclassed, who could check in the upper UIView when one is touched. To do this, use touchesBegan and touchesMoved function.

UITouch *touch = [ touches anyObject ];
CGPoint location = [ touch locationInView:view ];

With the location you can find if it's touching one of your 4 UIImageView and then doing what you want

2°) The other way, little more difficult but the one I prefer. You subclass UIImageView, animate them in this class, and when you get a touch Event stop the animation and do the same things that in 1°). By the way you may need to create a delegate to call function in others classes or use some Notifications

Good Luck ! Vincent
