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; }

这是

在本例中，aTextField是唯一的UITextField....如果有其他的uitextview，还有一点点事情要做。

// YourViewController.h
// ...
@interface YourViewController : UIViewController /* some subclass of UIViewController */ <UITextFieldDelegate> // <-- add this protocol
// ...
@end

// YourViewController.m

@interface YourViewController ()
@property (nonatomic, strong, readonly) UITapGestureRecognizer *singleTapRecognizer;
@end
// ...

@implementation
@synthesize singleTapRecognizer = _singleTapRecognizer;
// ...

- (void)viewDidLoad
{
    [super viewDidLoad];
    // your other init code here
    [self.view addGestureRecognizer:self.singleTapRecognizer];

{

- (UITapGestureRecognizer *)singleTapRecognizer
{
    if (nil == _singleTapRecognizer) {
        _singleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapToDismissKeyboard:)];
        _singleTapRecognizer.cancelsTouchesInView = NO; // absolutely required, otherwise "tap" eats events.
    }
    return _singleTapRecognizer;
}

// Something inside this VC's view was tapped (except the navbar/toolbar)
- (void)singleTapToDismissKeyboard:(UITapGestureRecognizer *)sender
{
    NSLog(@"singleTap");
    [self hideKeyboard:sender];
}

// When the "Return" key is pressed on the on-screen keyboard, hide the keyboard.
// for protocol UITextFieldDelegate
- (BOOL)textFieldShouldReturn:(UITextField*)textField
{
    NSLog(@"Return pressed");
    [self hideKeyboard:textField];
    return YES;
}

- (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.
    [aTextField resignFirstResponder];
    NSLog(@"keyboard hidden");
}

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    if let touch = touches.first{
     view.endEditing(true)

     }
}

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”。)

最好是让你的UIView成为UIControl的一个实例(在界面构建器中)，然后连接他们的TouchUpInside事件来解散键盘方法。这个IBAction方法看起来像:

- (IBAction)dismissKeyboard:(id)sender {
    [aTextBox resignFirstResponder];
}
