这是一个很好的通用解决方案:

objective - c:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.view endEditing:YES];    
}

迅速:

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    self.view.endEditing(true)
}

基于@icodebuster解决方案:https://stackoverflow.com/a/18756253/417652

@Jensen2k回答的Swift版本:

let gestureRecognizer : UITapGestureRecognizer = UITapGestureRecognizer.init(target: self, action: "dismissKeyboard")
self.view.addGestureRecognizer(gestureRecognizer)

func dismissKeyboard() {
    aTextField.resignFirstResponder()
}

一个衬套

self.view.addTapGesture(UITapGestureRecognizer.init(target: self, action: "endEditing:"))

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。

设置文本字段委托视图didload: 重载函数viewDidLoad() ｛ super.viewDidLoad () self. usertext .delegate = self ｝ 添加此函数: func textFieldShouldReturn(userText: UITextField! ｛ userText.resignFirstResponder () 返回true; ｝

发送消息resignFirstResponder的文本文件，把它放在那里。请参阅这篇文章了解更多信息。

只是使用这段代码在您的.m文件，它将辞职的文本字段，当用户点击文本字段之外。

 -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
  [textfield resignFirstResponder];
 }
