UIImageview上的UITapGesture不起作用

Question

我也在尝试使用 UITapGesture 将 UIImage 设为按钮。

let contactSegueIdentifier = "showContactSegue"

override func viewDidLoad() {
    initTapGestureRec()
}

func initTapGestureRec() {
    let tapGesture: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: Selector("recognizeTapGesture:"))
    brandMenuContactImage.addGestureRecognizer(tapGesture)
}

func recognizeTapGesture(sender: UIGestureRecognizer) {
    self.performSegueWithIdentifier(contactSegueIdentifier, sender: self)
}

当我运行并点击图像时，什么也没发生。谁能帮帮我。

Answer 1

在你的图片上添加userInteractionEnabledtrue 并尝试

brandMenuContactImage.userInteractionEnabled  = true

objective-C

 brandMenuContactImage.userInteractionEnabled  = YES;

更新

override func viewDidLoad() {
  brandMenuContactImage.userInteractionEnabled  = true
initTapGestureRec()
}
