问题 Ok guys, I am fairly new to objective C.

问题 Here's my problem. Am Using a scrollview whose Frames I am changing when rotating the device. I have 8 AsyncImageView on that scrollview. And the Images on AsyncImageView's are set by calling web services. Project runs fine. Images on the AsyncImageView are loaded properly.

I have a few draggable image view circles in my view and i want to prevent any overlapping between the image views. Im not looking for any serious collision solutions(friction, vectors, etc...), just something to stop the image views from going any further once they make contact with each other.
