触摸另一个控件（如按钮）Swift 2.0时如何隐藏键盘

Question

我已经阅读了这个页面：Close iOS Keyboard by touching anywhere using Swift了解如何隐藏键盘，当我触摸视图时它很好，但当我触摸按钮时它不起作用，有人知道吗？

Answer 1

将其粘贴到您的控制器中：

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

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

}

Answer 2

这是一个黑客，但它工作得很好，键盘甚至隐藏在背景上。我不确定按钮是否能解决您的问题，但请试一试！

编辑：尝试将UITapGestureRecognizer添加到您的按钮？

在viewDidLoad中添加代码：

self.hideKeyboardWhenTappedAround()

然后为ViewController添加一个扩展：

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

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

对我来说真的很好用。

SWIFT 4

将其添加到viewDidLoad。

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