objective - c:

在ViewController中添加这段代码。M文件:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.view endEditing:YES];
}

迅速:

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    view.endEditing(true)
}

我试了这里的很多回答，都不太走运。我的点击手势识别器总是导致我的UIButtons在点击时不响应，即使我将手势识别器的cancelsTouchesInView属性设置为NO。

这就是最终解决问题的方法:

有一个ivar:

UITapGestureRecognizer *_keyboardDismissGestureRecognizer;

当文本字段开始编辑时，设置手势识别器:

- (void) textFieldDidBeginEditing:(UITextField *)textField
{
    if(_keyboardDismissGestureRecognizer == nil)
    {
        _keyboardDismissGestureRecognizer = [[[UITapGestureRecognizer alloc]
                                       initWithTarget:self
                                       action:@selector(dismissKeyboard)] autorelease];
        _keyboardDismissGestureRecognizer.cancelsTouchesInView = NO;

        [self.view addGestureRecognizer:_keyboardDismissGestureRecognizer];
    }
}

窍门在于如何设置遣散键盘方法:

- (void) dismissKeyboard
{
    [self performSelector:@selector(dismissKeyboardSelector) withObject:nil afterDelay:0.01];
}

- (void) dismissKeyboardSelector
{
    [self.view endEditing:YES];

    [self.view removeGestureRecognizer:_keyboardDismissGestureRecognizer];
    _keyboardDismissGestureRecognizer = nil;
}

我猜有一些关于从触摸处理执行堆栈中获得dismissKeyboardSelector执行的东西…

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。

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");
}

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

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。
