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*/
}

override func viewDidLoad() {
        super.viewDidLoad()

self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(tap)))

}

func tap(sender: UITapGestureRecognizer){
        print("tapped")
        view.endEditing(true)
}

试试这个，很管用

viewDidLoad()方法中只有一行代码:

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

我发现最好的解决方案包括来自@Esqarrouth的接受答案，并进行了一些调整:

extension UIViewController {
    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "dismissKeyboardView")
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }

    func dismissKeyboardView() {
        view.endEditing(true)
    }
}

电话响了。cancelsTouchesInView = false是关键的:它确保UITapGestureRecognizer不会阻止视图上的其他元素接收用户交互。

方法解雇键盘()被更改为稍微不那么优雅的解雇keyboardview()。这是因为在我的项目相当旧的代码库中，有很多次已经使用了dismissKeyboard()(我想这并不少见)，导致编译器问题。

然后，如上所述，这个行为可以在各个视图控制器中启用:

override func viewDidLoad() {
    super.viewDidLoad()
    self.hideKeyboardWhenTappedAround() 
}

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*/
}

斯威夫特3

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