「Swift」 如何给UILabel添加点击事件

isUserInteractionEnabled 不设置为true将无法触发事件

label.isUserInteractionEnabled = true

class ViewController: UIViewController {

    @IBOutlet weak var label: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()

        let tap = UITapGestureRecognizer(target: self, action: #selector(tapHandle))
        label.isUserInteractionEnabled = true
        label.addGestureRecognizer(tap)
    }

    @objc
    func tapHandle(sender:UITapGestureRecognizer) {
        print("点击事件")
    }
}
