Adding gestures to a button in swift
提问by glasstongue
I'm trying to add gesture(swipe) functionality to an existing button in my view but I can't figure out how to attach the swipe to the button's area.
我正在尝试向视图中的现有按钮添加手势（滑动）功能，但我无法弄清楚如何将滑动附加到按钮区域。
The desired effect is to have a button I can press as well as swipe to produce different outcomes. So far the way I'm implementing gestures applies it to my entire view not just the button.
想要的效果是有一个按钮，我可以按下和滑动来产生不同的结果。到目前为止，我实现手势的方式将它应用于我的整个视图，而不仅仅是按钮。
I have a feeling it's pretty simple but it's been escaping me for a couple of days - I might just be searching for the wrong thing.
我有一种感觉，这很简单，但它已经让我逃避了几天 - 我可能只是在寻找错误的东西。
(I'm assigning '@IBOutlet var swipeButton: UIButton!' to my button BTW)
（顺便说一句，我正在将“@IBOutlet var swipeButton: UIButton!”分配给我的按钮）
Code below:
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")
}
}

If you want to add swipeGesture into Button then do it like this way:
如果要将 swipeGesture 添加到 Button 中，请按以下方式操作：
self.yourButton.addGestureRecognizer(swipeButtonDown)
and also there is a mistake in selector you sent it should be like:
并且您发送的选择器也有错误，它应该是这样的：
var swipeButtonDown: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "buttonDown")
change ButtonDownto buttonDown
更改ButtonDown为buttonDown
