如何在app中禁用缩放功能

RT，就是3个手指同时敲2下就可以缩放的zoom效果，在不改变系统设置那里的开关前提下，只在app游戏中不让出现这个效果退出游戏了则恢复zoom效果，请问怎么做呢？

	– (void)touchesBegan:(NSSet )touches withEvent:(UIEvent )event { } – (void)touchesCancelled:(NSSet )touches withEvent:(UIEvent )event{ } – (void)touchesEnded:(NSSet )touches withEvent:(UIEvent )event { } – (void)touchesMoved:(NSSet )touches withEvent:(UIEvent )event { } 用这三个方法，截获“3个手指同时敲2下”操作。然后自己处理下 NSUInteger numTaps = [[touches anyObject] tapCount];//点了几下 NSString tapsMessage = [[NSString alloc] initWithFormat:@”%d taps detected”, numTaps]; tapsLabel.text = tapsMessage; [tapsMessage release]; NSUInteger numTouches = [touches count];//几个触摸点 NSString touchMsg = [[NSString alloc] initWithFormat: @”%d touches detected”, numTouches]; touchesLabel.text = touchMsg; [touchMsg release];

40分	– (void)touchesBegan:(NSSet )touches withEvent:(UIEvent )event { } – (void)touchesCancelled:(NSSet )touches withEvent:(UIEvent )event{ } – (void)touchesEnded:(NSSet *)touches withE…… 监听你对View的手指操作，比如几个手指，点了几下，都可以获取的。
	没有吧？放在UIScrollView 或者实现UIScrollViewDelegate才会缩放吧。

	貌似 NSUInteger numTouches = [touches count];//几个触摸点总是得到1 什么情况呢
	不行呢，看了developer.app.com 里面说上面那套API只是捕捉单个手指触屏的 3个手指就不行所以能捕捉到连续拍了几下但是捕捉不到是几个手指拍的…… 求高人指点
