Detecting if UIView is intersecting other UIViews

Question

I have a bunch of UIViews on the screen. I would like to know what\'s the best to way to check if a particular view (which I have reference to) is intersection ANY other vie

Answer 1

First, create some array that stores the frames of all of your UIViews and their associated reference.

Then, potentially in a background thread, you can run some collision testing using what's in the array. For some simple collision testing for rectangles only, check out this SO question: Simple Collision Algorithm for Rectangles

Hope that helps!
