- (void)viewDidLoad
{
    [super viewDidLoad]; 

UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc]
                                                          initWithTarget:self
                                                          action:@selector(handleSingleTap:)];
    [singleTapGestureRecognizer setNumberOfTapsRequired:1];
    [singleTapGestureRecognizer requireGestureRecognizerToFail:singleTapGestureRecognizer];

    [self.view addGestureRecognizer:singleTapGestureRecognizer];
}

- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer
{
    [self.view endEditing:YES];
    [textField resignFirstResponder];
    [scrollView setContentOffset:CGPointMake(0, -40) animated:YES];

}

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");
}

在我的新发展中，我以巴里为例。它工作得很好!但我不得不包括一个轻微的变化，要求解散键盘，只有文本字段被编辑。

所以，我在Barry的例子中加入了以下内容:

- (void) textFieldDidBeginEditing:(UITextField *)textField
{
    _textBeingEdited = textField;
}
-(void) textFieldDidEndEditing:(UITextField *)textField
{
    _textBeingEdited = nil;
}

同时，我修改了hideKeyboard方法如下:

- (IBAction)hideKeyboard:(id)sender
{
    // Just call resignFirstResponder on all UITextFields and UITextViews in this VC
    // Why? Because it works and checking which one was last active gets messy.
    //UITextField * tf = (UITextField *) sender;
    [_textBeingEdited resignFirstResponder];
}

斯威夫特4

用这个扩展方法设置你的UIViewController，例如在viewDidLoad中:

override func viewDidLoad() {
    super.viewDidLoad()
    self.setupHideKeyboardOnTap()
}

即使点击导航栏，键盘也会被取消。

import UIKit
extension UIViewController {
    /// Call this once to dismiss open keyboards by tapping anywhere in the view controller
    func setupHideKeyboardOnTap() {
        self.view.addGestureRecognizer(self.endEditingRecognizer())
        self.navigationController?.navigationBar.addGestureRecognizer(self.endEditingRecognizer())
    }

    /// Dismisses the keyboard from self.view
    private func endEditingRecognizer() -> UIGestureRecognizer {
        let tap = UITapGestureRecognizer(target: self.view, action: #selector(self.view.endEditing(_:)))
        tap.cancelsTouchesInView = false
        return tap
    }
}

你可以在XCode 6及以上版本中使用Storyboard:

创建隐藏键盘的动作

将这个添加到ViewController使用的类的头文件中:

@interface TimeDelayViewController : UIViewController <UITextFieldDelegate>

- (IBAction)dissmissKeyboardOnTap:(id)sender;

@end

然后将这个添加到同一个ViewController的实现文件中:

- (IBAction)dissmissKeyboardOnTap:(id)sender{
    [[self view]endEditing:YES];
}

这将是你的故事板场景(即ViewController)的“Received Actions”之一:

将操作连接到用户事件

现在，您需要将这个动作与触碰键盘的用户手势连接起来。

重要-你需要将包含在故事板中的“UIView”转换为UIControl，这样它就可以接收事件。从视图控制器场景层次结构中选择视图:

.．.并更改其类:

现在从你的场景的“received action”旁边的小圆圈拖到你的场景的“空”部分(实际上你是在把“received action”拖到UIControl上)。你会看到一个事件的选择，你可以连接你的行动:

选择“touch up inside”选项。现在，您已经将创建的IBAction连接到触碰键盘的用户操作。当用户点击键盘时，它将被隐藏。

(注意:要将动作与事件挂钩，你也可以从接收到的动作直接拖到视图控制器层次结构中的UIControl上。它在层次结构中显示为“Control”。)

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; }
