我有2个UIImageView和一个TapGestureRecognitor。

 override func viewDidLoad() {
        // Do any additional setup after loading the view.

        super.viewDidLoad()

        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(cameraTapped(tapGestureRecognizer:)))

        cameraUIImageView.isUserInteractionEnabled = true
        cameraUIImageView.addGestureRecognizer(tapGestureRecognizer)

        plus1UIImageView.isUserInteractionEnabled = true
        plus1UIImageView.addGestureRecognizer(tapGestureRecognizer)
//        


    }

我只能点击第二个UIImageView,即plus1UIImageView。

A. UIGestureRecognizer 只能与单个视图一起使用。两个视图使用的是同一个对象。试试这个。

override func viewDidLoad() {
    // Do any additional setup after loading the view.

    super.viewDidLoad()

    let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(cameraTapped(tapGestureRecognizer:)))

    cameraUIImageView.isUserInteractionEnabled = true
    cameraUIImageView.addGestureRecognizer(tapGestureRecognizer)


    let tapGestureRecognizer2 = UITapGestureRecognizer(target: self, action: #selector(cameraTapped(tapGestureRecognizer:)))

    plus1UIImageView.isUserInteractionEnabled = true
    plus1UIImageView.addGestureRecognizer(tapGestureRecognizer2)        
}
