ios – 在swift中为按钮添加手势

所需的效果是有一个按钮,我可以按下以及滑动以产生不同的结果.到目前为止,我正在实现手势的方式将其应用于我的整个视图而不仅仅是按钮.

我觉得这很简单,但它已经让我逃脱了几天 – 我可能只是在寻找错误的东西.

(我将’@IBOutlet var swipeButton：UIButton！’分配给我的按钮BTW)

代码如下：

class ViewController: UIInputViewController {

@IBOutlet var swipeButton: UIButton!

let swipeRec = UISwipeGestureRecognizer()

override func viewDidLoad() {
    super.viewDidLoad()
    self.loadInterface()

    var swipeButtonDown: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self,action: "ButtonDown")
    swipeButtonDown.direction = UISwipeGestureRecognizerDirection.Down
    self.view.addGestureRecognizer(swipeButtonDown)
}

@IBAction func buttonPressed(sender: UIButton) {
    var proxy = textDocumentProxy as UITextDocumentProxy
    proxy.insertText("button")
}
func buttonDown(){
    var proxy = textDocumentProxy as UITextDocumentProxy
    proxy.insertText("swipe")
}

}
