Keyboard 触摸其他控件（如按钮）时如何隐藏键盘Swift 2.0

我读过这一页：

若要了解如何隐藏键盘，当我触摸view时很好，但当我触摸按钮时它不工作，有人知道吗？

将此粘贴到控制器中：

let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(YourViewController.dissmissKeyboard))
    view.addGestureRecognizer(tap)

 @objc func dissmissKeyboard() {
    view.endEditing(true)

}

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

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

将其粘贴到控制器中：

let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(YourViewController.dissmissKeyboard))
    view.addGestureRecognizer(tap)

 @objc func dissmissKeyboard() {
    view.endEditing(true)

}

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

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

这是一个相当黑客，但它的工作相当好，键盘甚至隐藏时，点击背景。我不确定它是否能解决你的按钮问题，但是试试看

编辑：是否尝试将UITapgestureRecognitor添加到按钮

在viewDidLoad中添加代码：

self.hideKeyboardWhenTappedAround()

然后将扩展添加到ViewController：

let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(YourViewController.dissmissKeyboard))
    view.addGestureRecognizer(tap)

 @objc func dissmissKeyboard() {
    view.endEditing(true)

}

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

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

对我来说效果非常好。

}

对我来说真的很好。

SWIFT 4

将此添加到viewDidLoad

 let endEditingTapGesture = UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing(_:)))
        endEditingTapGesture.cancelsTouchesInView = false
        view.addGestureRecognizer(endEditingTapGesture)

        view.addGestureRecognizer(endEditingTapGesture)
