Pan和2 Finger Pinch同步iOS – 同时 –

2手势识别器：

UIPinchGestureRecognizer *twoFingerPinch = 
[[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(handlePinch:)];
[croppper addGestureRecognizer:twoFingerPinch];

UIPanGestureRecognizer *PanRecognizer = [[[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)] autorelease];
[croppper addGestureRecognizer:PanRecognizer];

和：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {        
    return YES;
}

但同时捏和平底锅不起作用……
通常我可以捏,因为锅识别器已打开.

问候

解决方法

它看起来不像是为每个手势识别器设置委托. gestureRecognizer：shouldRecognizeSimultaneouslyWithGestureRecognizer：是一个委托方法,因此如果手势识别器没有委托,则不会调用此方法.

因此,默认返回值将为NO,因此不会同时识别手势.
