I have a, iOS 4.3.3 UIView that is touch-enabled. When my -touchesBegan:withEvent: method gets called, I can't figure out how to differentiate when the user touched the screen with one finger or with two. Either way, I receive this:
<UITouchesEvent: 0x1796e0> timestamp: 423888 touches: {(
<UITouch: 0x1d2ab0> phase: Began tap count: 1 window: <UIWindow: 0x197ac0; frame = (0 0; 768 1024); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x197c40>> view: <UIView: 0x1a1330; frame = (20 0; 748 1024); transform = [0, -1, 1, 0, 0, 0]; autoresize = W+H; layer = <CALayer: 0x1a13c0>> location in window: {572, 338} previous location in window: {572, 338} location in view: {686, 552} previous location in view: {686, 552}
)}
It tells me the 'tap count' but nowhere does it indicate if the user applied two fingers or just one. Instead of double-tapping or some other gesture, I need to make two fingers to mean 'quit the ongoing activity' to my program, whereas one finger means 'change value according to where the finger touched'.
Am I looking in the wrong place for this touch information?
