ios - UIscrollView 中的 UILabel 无法识别 UISwipegesture

Question

code:
lblQuestion = [[UILabel alloc]initWithFrame:CGRectMake(23, intQuesPos, 280, 100)];
    lblQuestion.numberOfLines = 0;
    UISwipeGestureRecognizer *topGesture = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeToptoBottom)];
    [topGesture setDirection:UISwipeGestureRecognizerDirectionDown];
    [lblQuestion addGestureRecognizer:topGesture];
    [scrollQuestion addSubview:lblQuestion];
    [vwQuestion addSubview:scrollQuestion];

我在 UIScrollView 中有 UILabel 并将 UISwipegesture 添加到 UILabel。当我向下滑动时，只检测到 UISCrollView。

我们将不胜感激。

使标签的 userInteractionEnabled 为真

    lblQuestion.userInteractionEnabled=YES;
