UILabel手势响应

Question

@IBOutlet weak var imageTitle: UILabel! 
@IBOutlet weak var profileImage: UIImageView! 

    func titleStyle(){ 
    imageTitle.layer.borderWidth = 1.0 
      imageTitle.layer.borderColor = UIColor.grayColor().CGColor 
      imageTitle.layer.cornerRadius = 10.0 

      // Apply Gesture to label 
      imageTitle.userInteractionEnabled = true 
      imageTitle.tag = 10 
      imageTitle.addGestureRecognizer(UIGestureRecognizer(target: self, action: "tappedLabel")) 
     } 

一些如何在代码轻击标签时看起来不起作用。

func tappedLabel(gesture: UIGestureRecognizer){ 
     print("Hi") 
    } 

Answer 1

我觉得你在添加动作时错过了“：”。

imageTitle.addGestureRecognizer(UIGestureRecognizer(target: self, action: "tappedLabel:")) 

Answer 2

我认为你的问题可能是在使用UIGestureRecognizer代替UITapGestureRecogniser

尝试：

imageTitle.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "tappedLabel:")) 

我不是100％肯定，为什么使用UIGestureRecognizer不起作用，但我自己也遇到了同样的问题，这对我很有帮助。
