问题描述：
我用下面的代码来处理我的应用程序中的触摸，我用touchesBegan循环在同一时间处理2个触摸，但问题是如果用户用2个手指拖动一个工作我可以正确地做2件作品吗？2 touch拖动问题
代码：
- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
- (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
touchesMoved代码：
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
