I have a grid of images. I want to create an effect so that when the finger dragging through "a line" of images, each image which is touched will do some event (say wobble for example) in the order of being touched.
I tried to set the action:forControlEvents, but I couldn't find any appropiate UIControlEventxxx.
I'm working in an UIViewController, so I guess it's impossible to use the UITouch..?
Any advice will be very appreciated !!
