ios - Swipe Gesture 多次调用该方法

Question

我有一个小问题 em 卡住了..我有一个自定义 UITableViewCell，在它的 textView 上我添加了 2 个手势， UITapGesture 和 UISwipeGesture..点击手势 工作正常，但滑动手势 调用方法多次.. 有时调用它两次，有时甚至更多......这是我将它们添加到单元格的方式

//added in cellForRowAtIndexPath Method
UITapGestureRecognizer *tapToTranslate = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapToTranslate:)];
[tapToTranslate setNumberOfTapsRequired:1];
[tapToTranslate setNumberOfTouchesRequired:1];
tapToTranslate.delegate = self;
[cell.messageContentView addGestureRecognizer:tapToTranslate];


UISwipeGestureRecognizer *swipeToTranslate = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(translateTo:)];
swipeToTranslate.numberOfTouchesRequired = 1;
swipeToTranslate.direction = UISwipeGestureRecognizerDirectionLeft;
swipeToTranslate.delegate = self;
[cell.messageContentView addGestureRecognizer: swipeToTranslate];

有这些方法……

-(void)tapToTranslate:(UITapGestureRecognizer *)aGesture {}

-(void)translateTo:(UISwipeGestureRecognizer *)aGesture 
{
    aGesture.enabled = false;
}

我尝试在调用后在其方法中禁用 Swipe Gesture，但这没有帮助..

我还有 uigesturerecognizer 委托(delegate)方法

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

所以任何帮助都会很棒......提前致谢……

UISwipeGestureRecognizer 会针对不同的状态多次调用该函数，例如 UIGestureRecognizerStateBegan、UIGestureRecognizerStateEnded 和其他几种状态。它还会在滑动时不断调用该函数，这可以在下面的最后一个 else 语句中处理。在滑动手势功能中，执行以下操作:

-(void)translateTo:(UISwipeGestureRecognizer *)aGesture
{
if (recognizer.state == UIGestureRecognizerStateBegan)
{
//do something
} 
else if(recognizer.state==UIGestureRecognizerStateEnded)
{
}
else
{
 //do something while it is swiping
}
}

以下答案可能与您打算做的不一致，但仍可能对您有所帮助:UISwipeGestureRecognizer called twice
