我一直在到处找这个,但我似乎找不到。我知道如何解雇使用Objective-C键盘,但我不知道如何使用Swift?有人知道吗?


当前回答

viewDidLoad()方法中只有一行代码:

view.addGestureRecognizer(UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing(_:))))

其他回答

另一种可能是在你可能需要触摸的所有视图下面添加一个没有内容的大按钮。 给它一个名为:

@IBAction func dismissKeyboardButton(sender: AnyObject) {
    view.endEditing(true)
}

对我来说,手势识别器的问题是,它也捕捉了我想通过tableViewCells接收的所有触摸。

您还可以添加一个点击手势识别器来重新使用键盘。: D

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let recognizer = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
    backgroundView.addGestureRecognizer(recognizer)
}
    func handleTap(recognizer: UITapGestureRecognizer) {
    textField.resignFirstResponder()
    textFieldtwo.resignFirstResponder()
    textFieldthree.resignFirstResponder()

    println("tappped")
}

可以通过在AppDelegate的窗口属性中添加全局点击手势识别器来实现这一点。

这是一种非常全面的方法,对某些人来说可能不是理想的解决方案,但对我来说很有效。请让我知道这个解决方案是否有任何陷阱。

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        // Globally dismiss the keyboard when the "background" is tapped.
        window?.addGestureRecognizer(
            UITapGestureRecognizer(
              target: window, 
              action: #selector(UIWindow.endEditing(_:))
            )
        )

        return true
    }
}

我得到了你

override func viewDidLoad() {
    super.viewDidLoad() /*This ensures that our view loaded*/
    self.textField.delegate = self /*we select our text field that we want*/   
    self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: Selector("dismissKeyboard")))
}

func dismissKeyboard(){ /*this is a void function*/
    textField.resignFirstResponder() /*This will dismiss our keyboard on tap*/
}

你可以使用swift

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    super.touchesBegan(touches, with: event)
    view.endEditing(true)

}
