这个解决方案为我工作，请注意这一行

[tableView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y-kbSize.height+160) animated:YES];

您可以更改160值以使其与您的工作相匹配

- (void)keyboardWasShown:(NSNotification*)aNotification
{
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    CGRect bkgndRect = activeField.superview.frame;
                        bkgndRect.size.height += kbSize.height;
     [activeField.superview setFrame:bkgndRect];
     [tableView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y-kbSize.height+160) animated:YES];
}

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
   activeField = textField;
}
-(void)textFieldDidEndEditing:(UITextField *)textField
 {
     activeField = nil;
 }
// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    tableView.contentInset = contentInsets;
    tableView.scrollIndicatorInsets = contentInsets;
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    CGRect bkgndRect = activeField.superview.frame;
    //bkgndRect.size.height += kbSize.height;
    [activeField.superview setFrame:bkgndRect];
    [tableView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y-kbSize.height) animated:YES];
}

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];

    }

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……

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)];
        }







    }

另一个简单的方法(只适用于一个部分)

//cellForRowAtIndexPath
UItextField *tf;
[cell addSubview:tf];
tf.tag = indexPath.row;
tf.delegate = self;

//textFieldDidBeginEditing:(UITextField *)text
[[self.tableView scrollToRowsAtIndexPath:[NSIndexPath indexPathForRow:text.tag in section:SECTIONINTEGER] animated:YES];

如果你使用uitableview来放置你的文本字段(来自Jeff Lamarche)，你可以像这样使用委托方法滚动tableview。

(注意:我的文本字段存储在一个数组中，索引与表视图中的行相同)

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

        int index;
        for(UITextField *aField in textFields){

            if (textField == aField){
                index = [textFields indexOfObject:aField]-1;
            }
        }

         if(index >= 0) 
            [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES];

        [super textFieldDidBeginEditing:textField];
    }
