title: How to Implement Touch Up Inside in touchesBegan, touchesEnded
body: <p>I'm wondering if someone knows how to implement the "touch up inside" response when a user pushes down then lifts their finger in the <code>touchesBegan</code>, <code>touchesEnded</code> methods. I know this can be done with  <code>UITapGestureRecognizer</code>, but actually I'm trying to make it so that it only works on a quick tap (with <code>UITapGestureRecognizer</code>, if you hold your finger there for a long time, then lift, it still executes). Anyone know how to implement this?</p>
