老实说，我对这里提出的任何解决方案都不感兴趣。我确实发现了一种使用TapGestureRecognizer的好方法，我认为它解决了问题的核心:当你点击键盘以外的任何东西时，忽略键盘。

In viewDidLoad, register to receive keyboard notifications and create a UITapGestureRecognizer: NSNotificationCenter *nc = [NSNotificationCenter defaultCenter]; [nc addObserver:self selector:@selector(keyboardWillShow:) name: UIKeyboardWillShowNotification object:nil]; [nc addObserver:self selector:@selector(keyboardWillHide:) name: UIKeyboardWillHideNotification object:nil]; tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTapAnywhere:)]; Add the keyboard show/hide responders. There you add and remove the TapGestureRecognizer to the UIView that should dismiss the keyboard when tapped. Note: You do not have to add it to all of the sub-views or controls. -(void) keyboardWillShow:(NSNotification *) note { [self.view addGestureRecognizer:tapRecognizer]; } -(void) keyboardWillHide:(NSNotification *) note { [self.view removeGestureRecognizer:tapRecognizer]; } The TapGestureRecognizer will call your function when it gets a tap and you can dismiss the keyboard like this: -(void)didTapAnywhere: (UITapGestureRecognizer*) recognizer { [textField resignFirstResponder]; }

这个解决方案的优点是它只过滤轻敲，而不是滑动。因此，如果你在键盘上方有滚动内容，滑动仍然会滚动并显示键盘。通过在键盘消失后移除手势识别器，未来在视图上的点击将被正常处理。

添加一个点击手势识别器到您的视图。并定义为ibaction

你的。m文件就像

    - (IBAction)hideKeyboardGesture:(id)sender {
    NSArray *windows = [UIApplication sharedApplication].windows;
    for(UIWindow *window in windows) [window endEditing:true];
    [[UIApplication sharedApplication].keyWindow endEditing:true];
}

这对我很有效

我最近需要使用的一个稍微健壮一点的方法:

- (void) dismissKeyboard {
    NSArray *windows = [UIApplication sharedApplication].windows;

    for(UIWindow *window in windows) [window endEditing:true];

    //  Or if you're only working with one UIWindow:

    [[UIApplication sharedApplication].keyWindow endEditing:true];
}

我发现其他一些“全局”方法不起作用(例如，UIWebView和WKWebView拒绝辞职)。

从UITableView和UIScrollView中取消键盘的最好方法是:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag

您可以递归地遍历子视图，存储所有UITextFields的数组，然后循环遍历它们并重新分配它们。

这并不是一个很好的解决方案，特别是当你有很多子视图时，但对于简单的应用程序来说，它应该是可行的。

我用一种更复杂，但更高效的方式解决了这个问题，但使用了我的应用程序的动画引擎的单例/管理器，任何时候一个文本字段成为响应器，我会将它分配给一个静态，它会根据某些其他事件被清除(辞职)…我几乎不可能用一段话解释清楚。

要有创意，在我发现这个问题后，我只花了10分钟就考虑了这个问题。
