I know this question is ancient, but I had the same problem and I thought I should give my 2 cents.
If your control has any subviews at all, beginTrackingWithTouch, touchesBegan, etc might not get called because those subviews are swallowing the touch events.
If you don’t want those subviews to handle touches, you can set userInteractionEnabled to NO, so the subviews simply passes the event through. Then you can override touchesBegan/touchesEnded and manage all your touches there.
Hope this helps.
