UIButton的单按和长按事件很快 [英] UIButton with single press and long press events swift

问题描述

我想在按钮上单击和按钮长按。我在界面构建器中添加了 UIbutton 。如何使用 IBAction 触发两个动作有人可以告诉我如何存档这个动作吗？

I want to trigger two action on button click and button long click. I have add a UIbutton in my interface builder. How can i trigger two action using IBAction can somebody tell me how to archive this ?

这是代码我用于点击按钮

this is the code i have used for a button click

@IBAction func buttonPressed（发件人：UIButton）{
....
}

我可以使用此方法，还是必须使用其他方法进行长时间点击？

can i use this method or do i have to use another method for long click ?

推荐答案

如果您想单击一下即可执行任何操作并长按，您可以通过以下方式添加手势：

If you want to perform any action with single tap you and long press the you can add gestures into button this way:

@IBOutlet weak var btn: UIButton!

override func viewDidLoad() {

    let tapGesture = UITapGestureRecognizer(target: self, action: "Tap")  //Tap function will call when user tap on button
    let longGesture = UILongPressGestureRecognizer(target: self, action: "Long") //Long function will call when user long press on button.
    tapGesture.numberOfTapsRequired = 1
    btn.addGestureRecognizer(tapGesture)
    btn.addGestureRecognizer(longGesture)
}

func Tap() {

    println("Tap happend")
}

func Long() {

    println("Long press")
}

这样你就可以为单个按钮添加多个方法，你只需要为该按钮选择Outlet。 。

This way you can add multiple method for single button and you just need Outlet for that button for that..
