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

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*/
}

其他回答

如果你有其他视图也应该接收触摸,你必须设置 cancelsTouchesInView = false

是这样的:

let elsewhereTap = UITapGestureRecognizer(target: self, action: #selector(dismissKeyboard))
    elsewhereTap.cancelsTouchesInView = false
    self.view.addGestureRecognizer(elsewhereTap)

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")
}

添加这个扩展到你的ViewController:

  extension UIViewController {
// Ends editing view when touches to view 
  open override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    super.touchesBegan(touches, with: event)
    self.view.endEditing(true)
  }
}

斯威夫特3: 关闭键盘的最简单方法:

  //Dismiss keyboard method
    func keyboardDismiss() {
        textField.resignFirstResponder()
    }

    //ADD Gesture Recignizer to Dismiss keyboard then view tapped
    @IBAction func viewTapped(_ sender: AnyObject) {
        keyboardDismiss()
    }

    //Dismiss keyboard using Return Key (Done) Button
    //Do not forgot to add protocol UITextFieldDelegate 
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        keyboardDismiss()

        return true
    }

你可以使用swift

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

}
