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，我将UISwipegesture 添加到UILabel。当我向下滑动时只检测到UISCrollView。

任何帮助将不胜感激。

提前致谢

为标签设置 userInteractionEnabled 为真

    lblQuestion.userInteractionEnabled=YES;
