是的，终止是最好的选择。从iOW 7.0开始，UIScrollView有一个很酷的功能，可以在与滚动视图交互时取消键盘。为此，你可以设置UIScrollView的keyboardDismissMode属性。

设置键盘解散模式为:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag

它几乎没有其他类型。看看这个苹果文档。

关于如何在iOS中当用户触摸屏幕上UITextField或键盘之外的任何地方时取消键盘的快速提示。考虑到iOS键盘所占用的空间，为用户提供一种简单直观的方式来消除键盘是有意义的。

这是一个链接

最简单的方法是调用方法

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
    if(![txtfld resignFirstResponder])
    {
        [txtfld resignFirstResponder];
    }
    else
    {

    }
    [super touchesBegan:touches withEvent:event];
}

我们很快就能做到

UIApplication.sharedApplication().sendAction("resignFirstResponder", to: nil, from: nil, forEvent: nil)

绝对的辉煌!

谢谢你！

考虑到你和其他人在这篇文章中的建议，以下是我所做的:

使用时的样子:

[[self appDelegate]解聘键盘];(注意:我添加了appDelegate作为NSObject的补充，所以我可以在任何地方使用任何东西)

引擎盖下的样子:

- (void)dismissKeyboard 
{
    UITextField *tempTextField = [[[UITextField alloc] initWithFrame:CGRectZero] autorelease];
    tempTextField.enabled = NO;
    [myRootViewController.view addSubview:tempTextField];
    [tempTextField becomeFirstResponder];
    [tempTextField resignFirstResponder];
    [tempTextField removeFromSuperview];
}

EDIT

修正我的回答包括tempTextField。enabled = NO;。禁用文本字段将阻止UIKeyboardWillShowNotification和UIKeyboardWillHideNotification键盘通知发送，如果你在整个应用程序中依赖这些通知。

杰里米的回答不太适合我，我想是因为我在一个选项卡视图中有一个导航堆栈，上面有一个模态对话框。我现在使用下面的，它是为我工作，但你的里程可能会有所不同。

 // dismiss keyboard (mostly macro)
[[UIApplication sharedApplication].delegate dismissKeyboard]; // call this in your to app dismiss the keybaord

// --- dismiss keyboard (in indexAppDelegate.h) (mostly macro)
- (void)dismissKeyboard;

// --- dismiss keyboard (in indexAppDelegate.m) (mostly macro)
// do this from anywhere to dismiss the keybard
- (void)dismissKeyboard {    // from: http://stackoverflow.com/questions/741185/easy-way-to-dismiss-keyboard

    UITextField *tempTextField = [[UITextField alloc] initWithFrame:CGRectZero];

    UIViewController *myRootViewController = <#viewController#>; // for simple apps (INPUT: viewController is whatever your root controller is called.  Probably is a way to determine this progragrammatically)
    UIViewController *uivc;
    if (myRootViewController.navigationController != nil) { // for when there is a nav stack
        uivc = myRootViewController.navigationController;
    } else {
        uivc = myRootViewController;
    }

    if (uivc.modalViewController != nil) { // for when there is something modal
        uivc = uivc.modalViewController;
    } 

    [uivc.view  addSubview:tempTextField];

    [tempTextField becomeFirstResponder];
    [tempTextField resignFirstResponder];
    [tempTextField removeFromSuperview];
    [tempTextField release];

}
