我想知道如何使键盘消失时,用户触摸以外的UITextField。

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");
}

其他回答

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];
 }

藏品视图:

// the keyboard follows the dragging touch off screen, and may be pulled upward again to cancel the dismiss
collectionView.keyboardDismissMode = .interactive
// dismisses the keyboard when a drag begins
collectionView.keyboardDismissMode = .onDrag

你可以为UiView创建类别并重写touchesBegan方法,如下所示。

这对我来说很好。这是一种集中解决这一问题的方法。

#import "UIView+Keyboard.h"
@implementation UIView(Keyboard)

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.window endEditing:true];
    [super touchesBegan:touches withEvent:event];
}
@end

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)
}
