对于那些在Swift中挣扎的人。这是Jensen2k在Swift中接受的答案。

斯威夫特2.3

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

        let viewTapGestureRec = UITapGestureRecognizer(target: self, action: #selector(handleViewTap(_:)))
        //this line is important
        viewTapGestureRec.cancelsTouchesInView = false
        self.view.addGestureRecognizer(viewTapGestureRec)

         //.....
    }

    func handleViewTap(recognizer: UIGestureRecognizer) {
        myTextField.resignFirstResponder()
    }

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。

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。

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
    super.view.endEditing(true)
    super.touchesBegan(touches, withEvent: event)
}

只是在这里添加我的版本如何在外部触摸时取消键盘。

viewDidLoad:

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
[self.view addGestureRecognizer:singleTap];

在任何地方:

-(void)handleSingleTap:(UITapGestureRecognizer *)sender{
    [textFieldName resignFirstResponder];
    puts("Dismissed the keyboard");
}
