iOS - 在 UITextField 之外触摸时关闭键盘 [英] iOS - Dismiss keyboard when touching outside of UITextField

问题描述

我想知道如何在用户触摸 UITextField 外部时让键盘消失.

I'm wondering how to make the keyboard disappear when the user touches outside of a UITextField.

推荐答案

您需要添加一个 UITapGestureRecogniser 并将其分配给视图，然后在 上调用 resign first responderUITextField 在它的选择器上.

You'll need to add an UITapGestureRecogniser and assign it to the view, and then call resign first responder on the UITextField on it's selector.

代码:

在 viewDidLoad

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];

[self.view addGestureRecognizer:tap];

关闭键盘:

-(void)dismissKeyboard 
{
    [aTextField resignFirstResponder];
}

(其中aTextField是负责键盘的文本框)

(Where aTextField is the textfield that is responsible for the keyboard)

Swift 3 版本看起来像那样

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.dismissKeyboard (_:)))
self.view.addGestureRecognizer(tapGesture)

对于解雇键盘

@objc func dismissKeyboard (_ sender: UITapGestureRecognizer) {
    aTextField.resignFirstResponder()
}
