在swift 5中，你可以使用以下代码来解除文本域外的键盘

override func viewDidLoad() {
    // ... code

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

@objc func dismissKeyboard(_ sender: UITapGestureRecognizer) {
    self.view.endEditing(true)
}

在swift 5中，你可以使用以下代码来解除文本域外的键盘

override func viewDidLoad() {
    // ... code

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

@objc func dismissKeyboard(_ sender: UITapGestureRecognizer) {
    self.view.endEditing(true)
}

如果我得到你的权利，你想辞职键盘狡猾敲在文本字段之外，但你没有你的文本字段的引用。

试试这个;

Take global textField, lets call it reftextField Now in textFieldDidBeginEditing set referenced text field to - (void) textFieldDidBeginEditing:(UITextField *)textField{ reftextField = textField; } Now you can happily use on any button clock, (adding a transparent button on begin editing recomended) - (void)dismissKeyboard { [reftextField resignFirstResponder]; } Or for resigning done button try this. //for resigning on done button - (BOOL) textFieldShouldReturn:(UITextField *)textField{ [textField resignFirstResponder]; return YES; }

我拼凑了几个答案。

使用一个在viewDidLoad期间初始化的ivar:

UIGestureRecognizer *tapper;

- (void)viewDidLoad
{
    [super viewDidLoad];
    tapper = [[UITapGestureRecognizer alloc]
                initWithTarget:self action:@selector(handleSingleTap:)];
    tapper.cancelsTouchesInView = NO;
    [self.view addGestureRecognizer:tapper];
}

删除当前正在编辑的内容:

- (void)handleSingleTap:(UITapGestureRecognizer *) sender
{
    [self.view endEditing:YES];
}

如果视图被嵌入到UIScrollView中，那么你可以使用以下方法:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;
tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;

前者会在表格视图滚动时将键盘动画化，后者会像股票消息应用程序一样隐藏键盘。

注意，这些都可以在iOS 7.0或更高版本上使用。

在这种情况下，可以使用ScrollView，并添加到文本字段在ScrollView和我想点击ScrollView和视图，然后解散键盘。为了以防万一，我尝试创建了示例代码。像这样,

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var scrollView: UIScrollView!
    @IBOutlet weak var textField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(ViewController.tap(_:)))
        view.addGestureRecognizer(tapGesture)
        // Do any additional setup after loading the view, typically from a nib.
    }
    func tap(gesture: UITapGestureRecognizer) {
        textField.resignFirstResponder()
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

你的故事板看，就像。
