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;
}
但同时捏和平移不起作用...通常我可以捏,因为泛识别器已打开。
问候
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。
您是否将自己设定为识别者代表?
[twoFingerPinch setDelgate:self];
...
[PanRecognizer setDelegate:self];
PS我也试图为你的变量获得更一致的命名方案!
