如何以手勢識別器作為參數傳遞UIView？

Question

我用：

  tap.addTarget(self, action: "handleTap:")
  self.view.addGestureRecognizer(tap)

我想在handleTap方法中訪問view的view.tag屬性。 那么，如何通過UIView中的“ tap”作為handleTap的參數呢？

謝謝。

Answer 1

func handleTap(sender:UITapGestureRecognizer) {
    if let tag = sender.view?.tag {
        println(tag)
    }
}

Answer 2

嘗試以下代碼。

 override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
        self.view.userInteractionEnabled = true
        var tapGesture = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
        self.view.tag = 101
        self.view.addGestureRecognizer(tapGesture)
    }

    func handleTap(sender:UITapGestureRecognizer) {
        if let tag = sender.view?.tag {
            println(tag)
        }
    }
