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];
}

你可以使用UITapGestureRecongnizer方法通过点击UITextField之外的按钮来取消键盘。通过使用这个方法，每当用户在UITextField之外点击时，键盘就会被驳回。下面是使用它的代码片段。

 UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
                                   initWithTarget:self
                                   action:@selector(dismissk)];

    [self.view addGestureRecognizer:tap];


//Method
- (void) dismissk
{
    [abctextfield resignFirstResponder];
    [deftextfield resignFirstResponder];

}

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; }

Swift版本，这与其他元素(如UIButton或另一个UITextField)结合使用:

override func viewDidLoad() {
    super.viewDidLoad()

    let tapper = UITapGestureRecognizer(target: self, action:#selector(endEditing))
    tapper.cancelsTouchesInView = false
    view.addGestureRecognizer(tapper)
}

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");
}

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");
}
