如何为iOS3设备实现手势识别器?

How can I implement gesture recognizers for iOS3 devices?

推荐答案

UITapGestureRecognizer *singleFingerDTap = [[UITapGestureRecognizer alloc]
        initWithTarget:self action:@selector(handleSingleDoubleTap:)];  
singleFingerDTap.numberOfTapsRequired = 2;  
[self.view addGestureRecognizer:singleFingerDTap];  
[singleFingerDTap release];

此功能在iOS 3.2及更高版本中可用.不幸的是，对于iPad.

This is available in iOS 3.2 onwards. Unfortunately for iPad.

您可能应该在iPhone的iOS 3中使用UITouch方法.

You probably should go for UITouch methods then in iOS 3 for iPhone.
