UIPinchGestureRecognizer问题

Question

我正在使用UIPinchGestureRecognizer.can我写了两个用于捏合和捏合的动作..是否有任何特定的方法(委托)？我只写了一个当我捏入时被调用...

  UIPinchGestureRecognizer *pinchGesture = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(handlePinchGesture:)];
[self.view addGestureRecognizer:pinchGesture]; 
[pinchGesture release];

你可以查看手势.scale了-handlePinchGesture:.如果它<1,则是捏合,否则是捏合.
