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];
        }

简单快捷的解决方案。

我只要滚动到右边的单元格

    - (void)scrollViewDidScroll:(UIScrollView *)scrollView 

假设我知道表现在处于这个模式_keepMyCellOnTop &我知道选定单元格“_selectedCellIndex”或滚动到选定单元格

- (void)scrollViewDidScroll:(UIScrollView *)scrollView 
{

    if (_keepMyCellOnTop)
    {
        [self.tableView scrollToRowAtIndexPath:_selectedCellIndex atScrollPosition:UITableViewScrollPositionTop animated:NO];
    }
}

这将防止滚动。

将代码放在-(void) scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView中 结果是上下滚动吗

我正在用这些，它们就像魔法一样管用:

键盘通知可以工作，但苹果的示例代码假设滚动视图是窗口的根视图。通常情况并非如此。您必须补偿标签栏等，以获得正确的偏移量。

这比听起来容易。下面是我在UITableViewController中使用的代码。它有两个实例变量，hiddenRect和keyboardshow。

// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification {
    if (keyboardShown)
        return;

    NSDictionary* info = [aNotification userInfo];

    // Get the frame of the keyboard.
    NSValue *centerValue = [info objectForKey:UIKeyboardCenterEndUserInfoKey];
    NSValue *boundsValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
    CGPoint keyboardCenter = [centerValue CGPointValue];
    CGRect keyboardBounds = [boundsValue CGRectValue];
    CGPoint keyboardOrigin = CGPointMake(keyboardCenter.x - keyboardBounds.size.width / 2.0,
                                         keyboardCenter.y - keyboardBounds.size.height / 2.0);
    CGRect keyboardScreenFrame = { keyboardOrigin, keyboardBounds.size };


    // Resize the scroll view.
    UIScrollView *scrollView = (UIScrollView *) self.tableView;
    CGRect viewFrame = scrollView.frame;
    CGRect keyboardFrame = [scrollView.superview convertRect:keyboardScreenFrame fromView:nil];
    hiddenRect = CGRectIntersection(viewFrame, keyboardFrame);

    CGRect remainder, slice;
    CGRectDivide(viewFrame, &slice, &remainder, CGRectGetHeight(hiddenRect), CGRectMaxYEdge);
    scrollView.frame = remainder;

    // Scroll the active text field into view.
    CGRect textFieldRect = [/* selected cell */ frame];
    [scrollView scrollRectToVisible:textFieldRect animated:YES];

    keyboardShown = YES;
}


// Called when the UIKeyboardDidHideNotification is sent
- (void)keyboardWasHidden:(NSNotification*)aNotification
{
    // Reset the height of the scroll view to its original value
    UIScrollView *scrollView = (UIScrollView *) self.tableView;
    CGRect viewFrame = [scrollView frame];
    scrollView.frame = CGRectUnion(viewFrame, hiddenRect);

    keyboardShown = NO;
}

非常有趣的讨论线程，我也面临着同样的问题，可能更糟糕的一个原因

我正在使用一个自定义单元格和文本字段在里面。 我不得不使用UIViewController来满足我的要求，所以不能利用UITableViewController。 我有过滤/排序标准在我的表格单元格，即你的单元格不断改变和跟踪indexpath和所有将没有帮助。

所以阅读这里的帖子并实现我的版本，这帮助我在iPad的横屏模式下提升我的内容。 这里是代码(这不是傻瓜证明，但它修复了我的问题) 首先，你需要在你的自定义单元格类中有一个委托，在编辑开始时，将文本字段发送到你的视图控制器，并设置activefield = theTextField

//只处理横向模式

- (void)keyboardWasShown:(NSNotification*)aNotification
{
    NSDictionary* info = [aNotification userInfo];
    CGSize kbValue = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    CGRect aRect = myTable.frame;

    CGSize kbSize = CGSizeMake(kbValue.height, kbValue.width);

    aRect.size.height -= kbSize.height+50;
// This will the exact rect in which your textfield is present
        CGRect rect =  [myTable convertRect:activeField.bounds fromView:activeField];
// Scroll up only if required
    if (!CGRectContainsPoint(aRect, rect.origin) ) {


            [myTable setContentOffset:CGPointMake(0.0, rect.origin.y) animated:YES];

    }


}

//当发送UIKeyboardWillHideNotification时调用

- (void)keyboardWillHide:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    myTable.contentInset = contentInsets;
    myTable.scrollIndicatorInsets = contentInsets;
    NSDictionary* info = [aNotification userInfo];
    CGSize kbValue = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    CGSize kbSize = CGSizeMake(kbValue.height, kbValue.width);
    CGRect bkgndRect = activeField.superview.frame;
    bkgndRect.size.height += kbSize.height;
    [activeField.superview setFrame:bkgndRect];
    [myTable setContentOffset:CGPointMake(0.0, 10.0) animated:YES];
}

在viewdidload

-(void)viewdidload{

[super viewdidload];

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

    -(void)keyboardWillChange:(NSNotification*)sender{

        NSLog(@"keyboardwillchange sender %@",sender);

float margin=0  // set your own topmargin


        CGFloat originY = [[sender.userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].origin.y;


        if (originY >= self.view.frame.size.height){

            NSLog(@"keyboardclose");



            [tb_ setFrame:CGRectMake(0, margin, self.view.frame.size.width, self.view.frame.size.height-margin)];

        }else{

            NSLog(@"keyobard on");

            float adjustedHeight = self.view.frame.size.height - margin - (self.view.frame.size.height-originY);

            [tb_ setFrame:CGRectMake(0, margin, self.view.frame.size.width, adjustedHeight)];
        }
