我希望你们读了这些已经找到了答案。但我找到了我的解决方案如下。我期待你已经有一个单元与UITextField。在准备时，保持行索引到文本字段的标签中。

cell.textField.tag = IndexPath.row;

创建一个activeTextField, UITextField实例的全局作用域如下所示:

@interface EditViewController (){

    UITextField *activeTextField;

}

现在你只需要在最后复制粘贴我的代码。别忘了添加UITextFieldDelegate

#pragma mark - TextField Delegation

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{

    activeTextField = textField;

    return YES;
}

- (void)textFieldDidEndEditing:(UITextField *)textField{

    activeTextField = nil;

}

注册键盘通知

#pragma mark - Keyboard Activity

- (void)registerForKeyboardNotifications

{

    [[NSNotificationCenter defaultCenter] addObserver:self

                                         selector:@selector(keyboardWasShown:)

                                             name:UIKeyboardDidShowNotification object:nil];



    [[NSNotificationCenter defaultCenter] addObserver:self

                                         selector:@selector(keyboardWillBeHidden:)

                                             name:UIKeyboardWillHideNotification object:nil];



}

处理键盘通知:

当发送UIKeyboardDidShowNotification时调用。

- (void)keyboardWasShown:(NSNotification*)aNotification

{

    NSDictionary* info = [aNotification userInfo];

    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);

    [self.tableView setContentInset:contentInsets];

    [self.tableView setScrollIndicatorInsets:contentInsets];

    NSIndexPath *currentRowIndex = [NSIndexPath indexPathForRow:activeTextField.tag inSection:0];

    [self.tableView scrollToRowAtIndexPath:currentRowIndex atScrollPosition:UITableViewScrollPositionTop animated:YES];

}

当UIKeyboardWillHideNotification被发送时调用

- (void)keyboardWillBeHidden:(NSNotification*)aNotification

{

    UIEdgeInsets contentInsets = UIEdgeInsetsZero;

    [self.tableView setContentInset:contentInsets];

    [self.tableView setScrollIndicatorInsets:contentInsets];

}

现在还剩下一件事，在ViewDidLoad方法中调用registerForKeyboardNotifications方法，如下所示:

- (void)viewDidLoad {

    [super viewDidLoad];

    // Registering keyboard notification

    [self registerForKeyboardNotifications];

    // Your codes here...

}

你完成了，希望你的文本字段将不再隐藏在键盘。

如果你使用Three20，那么使用autoresizesForKeyboard属性。只要在视图控制器的-initWithNibName:bundle方法中设置

self.autoresizesForKeyboard = YES

这涉及到:

监听键盘通知并调整表视图的框架 滚动到第一个响应器

搞定了。

这非常有效，在iPad上也是如此。

- (BOOL)textFieldShouldReturn:(UITextField *)textField 
{

    if(textField == textfield1){
            [accountName1TextField becomeFirstResponder];
        }else if(textField == textfield2){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield3 becomeFirstResponder];

        }else if(textField == textfield3){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield4 becomeFirstResponder];

        }else if(textField == textfield4){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:2 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield5 becomeFirstResponder];

        }else if(textField == textfield5){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:3 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield6 becomeFirstResponder];

        }else if(textField == textfield6){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:4 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield7 becomeFirstResponder];

        }else if(textField == textfield7){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:5 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield8 becomeFirstResponder];

        }else if(textField == textfield8){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:6 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textfield9 becomeFirstResponder];

        }else if(textField == textfield9){
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:7 inSection:1] atScrollPosition:UITableViewScrollPositionTop animated:YES];
            [textField resignFirstResponder];
        }

我可能错过了这一点，因为我没有阅读整篇文章，但我想到的似乎很简单。我并没有在所有情况下进行测试，但它看起来应该工作得很好。

简单地根据键盘的高度调整tableview的contentInset，然后将单元格滚动到底部:

- (void)keyboardWasShown:(NSNotification *)aNotification
{
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
    self.myTableView.contentInset = contentInsets;
    self.myTableView.scrollIndicatorInsets = contentInsets;

    [self.myTableView scrollToRowAtIndexPath:self.currentField.indexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];
}

当然

- (void)keyboardWasHidden:(NSNotification *)aNotification
{
    [UIView animateWithDuration:.3 animations:^(void) 
    {
        self.myTableView.contentInset = UIEdgeInsetsZero;
        self.myTableView.scrollIndicatorInsets = UIEdgeInsetsZero;
    }];
}

这是不是太简单了?我遗漏了什么吗?到目前为止，它对我来说还不错，但就像我说的，我还没有把它经过折腾……

我经常在我的项目中使用这个。这个解决方案适用于滚动视图，表视图或集合视图，它很容易设置。 它还自动连接键盘上的“下一步”按钮，在文本字段之间切换。

我尝试了几乎相同的方法，并提出了一个更简单、更小的代码。 我创建了一个IBOutlet iTextView，并与IB中的UITextView相关联。

 -(void)keyboardWillShow:(NSNotification *)notification
    {
        NSLog(@"Keyboard");
        CGRect keyFrame = [[[notification userInfo]objectForKey:UIKeyboardFrameEndUserInfoKey]CGRectValue];

        [UIView beginAnimations:@"resize view" context:nil];
        [UIView setAnimationCurve:1];
        [UIView setAnimationDuration:1.0];
        CGRect frame = iTableView.frame;
        frame.size.height = frame.size.height -  keyFrame.size.height;
        iTableView.frame = frame;
        [iTableView scrollRectToVisible:frame animated:YES];
        [UIView commitAnimations];

    }
