Question

屏幕的某些部分有UIView。这个UIView有Pan手势识别器。这个UIView（mainVw）有一个完全覆盖UIView的UITextView。此UITextview具有滑动手势（左侧和写入）。

我的问题是当我向左或向右滑动时，UIView也开始拖动。我想要的是，当我拖动UIView它应该拖动，当我滑动UITextView时应该向左滑动写入但不拖动。

以下是我用来更好理解的代码：

UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
    [panGesture setMinimumNumberOfTouches:1];
    panGesture.delegate =(id)self;
    [self.mainVw addGestureRecognizer:panGesture];
    //[self.mainVw.layer setValue:[NSValue valueWithCGPoint:vwCaptionBg.center] forKey:@"originalCenter"];


UISwipeGestureRecognizer *rightRecognizer;
rightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanTouch:)];
[rightRecognizer setDirection: UISwipeGestureRecognizerDirectionRight];
rightRecognizer.delegate=(id)self;
[self.txtVw addGestureRecognizer:rightRecognizer];


UISwipeGestureRecognizer *vwLeftRecognizer;
vwLeftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanTouch:)];
[vwLeftRecognizer setDirection: UISwipeGestureRecognizerDirectionLeft];
vwLeftRecognizer.delegate=(id)self;
[self.txtVw addGestureRecognizer:vwLeftRecognizer];

您可以尝试使用[GESTURE requireGestureRecognizerToFail:GESTURE_TO_FAIL];方法。这将是您的滑动将需要在允许继续进行平移之前失败。

您还可以使用委托方法进行同步手势。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

或者您可以使用这些委托方法中的任何一种使用您自己的逻辑。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer

手势识别器
