Question

以下是我在UITableView上点了两根手指的代码：

UISwipeGestureRecognizer *leftSwipe = [UISwipeGestureRecognizer new];
[leftSwipe addTarget:self action:@selector(nextDay)];
leftSwipe.numberOfTouchesRequired = 2;
leftSwipe.direction = UISwipeGestureRecognizerDirectionLeft;
leftSwipe.delegate = self;
[leftSwipe setCancelsTouchesInView:YES];
[tableViewTasks addGestureRecognizer:leftSwipe];

UISwipeGestureRecognizer *rightSwipe = [UISwipeGestureRecognizer new];
[rightSwipe addTarget:self action:@selector(previousDay)];
rightSwipe.numberOfTouchesRequired = 2;
rightSwipe.direction = UISwipeGestureRecognizerDirectionRight;
rightSwipe.delegate = self;
[rightSwipe setCancelsTouchesInView:YES];
[tableViewTasks addGestureRecognizer:rightSwipe];

我正在使用SWTableViewCell左右（单击）gestureRecognisers 使用2根手指左/右滑动UITableView时，SWTableViewCell左右手势也会被触发。
如何制止冲突？

Answer 1

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
    if (SWTableViewCellTouch) {
        SWTableViewCellTouch = NO
        return NO;
    }

    return YES;
}

当您触摸SWTableViewCell时，将BOOL SWTableViewCellTouch设置为YES。

Answer 2

可能的解决方案是在touchesBegan：方法中启用/禁用BOOl（SWTableViewCellTouch），如下所示。

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
   if ([[event touchesForView:self] count] > 1) {
   // Its two finger touch so set the BOOL false like
   SWTableViewCellTouch = NO;
   }
   else if ([[event touchesForView:self] count] == 1){
    // Its sigle finger touch so set the BOOL true like
    SWTableViewCellTouch = YES;
   }
[super touchesBegan:touches withEvent:event] ;}

希望这会对你有所帮助。

Answer 3

1。在UIGestureRecognizerDelegate

中实施UIViewController

2。设置leftSwipe.delegate = self;和leftSwipe.delegate = self;

3. 现在检查UISwipeGesture中的委托方法是否有多少numberOfTouchesRequired

 -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
    {
    if ( [gestureRecognizer isMemberOfClass:[UISwipeGestureRecognizer class]] ) {

    UISwipeGestureRecognizer  *swipeGesture=(UISwipeGestureRecognizer *)gestureRecognizer ;

    if(swipeGesture.numberOfTouchesRequired!=2)
     {    
    //if Double not Double Swipe Touch Don't Linsten Gesture in your Viewcontroller
     return NO;
      }
     }

        return YES; 
    }

我希望这能解决你的问题
