when I run my project in ios7 devices, I feel some lag between touch-down to ccTouchBegan() calling.
I tested it by log some text on ccTouchBegan().
when I touch some point on screen, keep finger down without any movements, ccTouchBegan() called after 100~300ms.
if I touch up (or dragging to other point) immediately, ccTouchBegan() called immediately.
maybe it happens only on above situation. (keep finger down without dragging).
I tested it on iPhone4(ios7), iPhone5(ios7), iPhone4S(ios6), iPhone Simulator(ios7).
this problem only appeared on iPhone4, iPhone5 (both ios7 devices).
in iPhone4S, iPhone Simulator, no lag appeared.
I think this is cocos2d-x compatibility issue on ios7 devices.
please, give me some comment.
