Uitableview UIGestureRecognitor中的UIGestureRecognitor类型捕获应开始

我想了解

UIgestureRecognitor

的类型。 我可以这样做吗

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    NSLog(@"Gesture should begin");
    if ([gestureRecognizer isMemberOfClass:[UIRotationGestureRecognizer class]])
        NSLog(@"rotate");
    if ([gestureRecognizer isMemberOfClass:[UIPinchGestureRecognizer class]])
        NSLog(@"pinch");
    if ([gestureRecognizer isMemberOfClass:[UITapGestureRecognizer class]])
        NSLog(@"tap");
    if ([gestureRecognizer isMemberOfClass:[UIPanGestureRecognizer class]])
        NSLog(@"pan");
    if ([gestureRecognizer isMemberOfClass:[UILongPressGestureRecognizer class]])
        NSLog(@"long");
    if ([gestureRecognizer isMemberOfClass:[UISwipeGestureRecognizer class]])
        NSLog(@"swipe");
    return NO;
}

我在桌面视图单元中有一个长的触摸手势。 如果我按下该单元格，我将收到一条日志：

-[FileObjectView gestureRecognizerShouldBegin:] [Line 45] Gesture should begin
-[FileObjectView gestureRecognizerShouldBegin:] [Line 55] long

-[FileObjectView gestureRecognizerShouldBegin:] [Line 45] Gesture should begin

我希望它能这样工作

但有时，当我滚动表格视图时，会收到日志：

-[FileObjectView gestureRecognizerShouldBegin:] [Line 45] Gesture should begin
-[FileObjectView gestureRecognizerShouldBegin:] [Line 55] long

-[FileObjectView gestureRecognizerShouldBegin:] [Line 45] Gesture should begin

这让我觉得我没有意识到某种姿势

有人能解释一下情况吗？

我决定这样检查类名：

NSLog(@"%@",gestureRecognizer.class);

类名为：

UIScrollViewPangTestureRecognitor

我已经在不同的iOS版本上多次检查过这个问题

这种情况只在iOS 6上发生。再来一个iOS 6错误

是的，这对我很有效。。
