从UITableView和UIScrollView中取消键盘的最好方法是:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag

这里有很多过于复杂的答案，也许是因为这在iOS文档中不容易找到。约瑟夫在上面写着:

[[view window] endEditing:YES];

@Nicholas Riley &@Kendall Helmstetter Geln & @cannyboy：

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。

Try:

[self.view endEditing:YES];

你应该发送enditing:到工作窗口作为UIView的子类

[[UIApplication sharedApplication].windows.firstObject endEditing:NO];

子类化你的文本字段…还有textviews

在子类中放入此代码..

-(void)conformsToKeyboardDismissNotification{

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(dismissKeyBoard) name:KEYBOARD_DISMISS object:nil];
}

-(void)deConformsToKeyboardDismissNotification{

    [[NSNotificationCenter defaultCenter] removeObserver:self name:KEYBOARD_DISMISS object:nil];
}

- (void)dealloc{
    [[NSNotificationCenter defaultCenter] removeObserver:self];
    [self resignFirstResponder];
}

在textfield委托中(类似于textview委托)

-(void)textFieldDidBeginEditing:(JCPTextField *)textField{
     [textField conformsToKeyboardDismissNotification];
}


- (void)textFieldDidEndEditing:(JCPTextField *)textField{
    [textField deConformsToKeyboardDismissNotification];
}

都准备好了. .现在只需从代码中的任何地方发布通知。它将放弃任何键盘。
