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];

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];
        }

如果你使用UITableViewController而不是UIViewController，它会自动这样做。

Swift 3-4动画和键盘帧改变的解决方案:

首先，创建Bool类型:

// MARK: - Private Properties
private var isKeyboardShowing = false

其次，在系统键盘通知中添加观察者:

// MARK: - Overriding ViewController Life Cycle Methods
override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: .UIKeyboardWillShow, object: nil)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: .UIKeyboardWillHide, object: nil)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillChangeFrame), name: .UIKeyboardWillChangeFrame, object: nil)
}

第三，准备动画功能:

func adjustTableViewInsets(keyboardHeight: CGFloat, duration: NSNumber, curve: NSNumber){
    var extraHeight: CGFloat = 0
    if keyboardHeight > 0 {
        extraHeight = 20
        isKeyboardShowing = true
    } else {
        isKeyboardShowing = false
    }

    let contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardHeight + extraHeight, right: 0)
    func animateFunc() {
        //refresh constraints
        //self.view.layoutSubviews()
        tableView.contentInset = contentInset
    }

    UIView.animate(withDuration: TimeInterval(duration), delay: 0, options: [UIViewAnimationOptions(rawValue: UInt(curve))], animations: animateFunc, completion: nil)
}

然后添加target/action方法(由观察者调用):

// MARK: - Target/Selector Actions
func keyboardWillShow(notification: NSNotification) {
    if !isKeyboardShowing {
        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
            let keyboardHeight = keyboardSize.height

            let duration = notification.userInfo?[UIKeyboardAnimationDurationUserInfoKey] as! NSNumber
            let curve = notification.userInfo?[UIKeyboardAnimationCurveUserInfoKey] as! NSNumber

            adjustTableViewInsets(keyboardHeight: keyboardHeight, duration: duration, curve: curve)
        }
    }
}

func keyboardWillHide(notification: NSNotification) {
    let duration = notification.userInfo?[UIKeyboardAnimationDurationUserInfoKey] as! NSNumber
    let curve = notification.userInfo?[UIKeyboardAnimationCurveUserInfoKey] as! NSNumber
    adjustTableViewInsets(keyboardHeight: 0, duration: duration, curve: curve)
}

func keyboardWillChangeFrame(notification: NSNotification) {
    if isKeyboardShowing {
        let duration = notification.userInfo?[UIKeyboardAnimationDurationUserInfoKey] as! NSNumber
        let curve = notification.userInfo?[UIKeyboardAnimationCurveUserInfoKey] as! NSNumber

        if let newKeyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
            let keyboardHeight = newKeyboardSize.height
            adjustTableViewInsets(keyboardHeight: keyboardHeight, duration: duration, curve: curve)
        }
    }
}

最后，不要忘记在deinit或viewWillDisappear中删除观察者:

deinit {
    NotificationCenter.default.removeObserver(self)
}

如果你的UITableView是由UITableViewController的子类管理的，而不是UITableView，并且文本字段委托是UITableViewController，它应该自动管理所有的滚动——所有这些其他注释在实践中是很难实现的。

有关一个好例子，请参阅apple示例代码项目:TaggedLocations。

你可以看到它自动滚动，但似乎没有任何代码做到这一点。该项目还具有自定义表视图单元格，因此，如果使用它作为指南构建应用程序，应该会得到预期的结果。

如果你能使用UITableViewController，你就能免费得到这个功能。然而，有时这不是一个选项，特别是当你需要多个视图而不仅仅是UITableView时。

这里介绍的一些解决方案在iOS≥4上不起作用，一些在iPad或横屏模式下不起作用，一些不适用于蓝牙键盘(我们不希望有任何滚动)，一些在多个文本字段之间切换时不起作用。因此，如果您选择任何解决方案，请确保测试这些情况。这是我们在InAppSettingsKit中使用的解决方案:

- (void)_keyboardWillShow:(NSNotification*)notification {
    if (self.navigationController.topViewController == self) {
        NSDictionary* userInfo = [notification userInfo];

        // we don't use SDK constants here to be universally compatible with all SDKs ≥ 3.0
        NSValue* keyboardFrameValue = [userInfo objectForKey:@"UIKeyboardBoundsUserInfoKey"];
        if (!keyboardFrameValue) {
            keyboardFrameValue = [userInfo objectForKey:@"UIKeyboardFrameEndUserInfoKey"];
        }

        // Reduce the tableView height by the part of the keyboard that actually covers the tableView
        CGRect windowRect = [[UIApplication sharedApplication] keyWindow].bounds;
        if (UIInterfaceOrientationLandscapeLeft == self.interfaceOrientation ||UIInterfaceOrientationLandscapeRight == self.interfaceOrientation ) {
            windowRect = IASKCGRectSwap(windowRect);
        }
        CGRect viewRectAbsolute = [_tableView convertRect:_tableView.bounds toView:[[UIApplication sharedApplication] keyWindow]];
        if (UIInterfaceOrientationLandscapeLeft == self.interfaceOrientation ||UIInterfaceOrientationLandscapeRight == self.interfaceOrientation ) {
            viewRectAbsolute = IASKCGRectSwap(viewRectAbsolute);
        }
        CGRect frame = _tableView.frame;
        frame.size.height -= [keyboardFrameValue CGRectValue].size.height - CGRectGetMaxY(windowRect) + CGRectGetMaxY(viewRectAbsolute);

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
        [UIView setAnimationCurve:[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]];
        _tableView.frame = frame;
        [UIView commitAnimations];

        UITableViewCell *textFieldCell = (id)((UITextField *)self.currentFirstResponder).superview.superview;
        NSIndexPath *textFieldIndexPath = [_tableView indexPathForCell:textFieldCell];

        // iOS 3 sends hide and show notifications right after each other
        // when switching between textFields, so cancel -scrollToOldPosition requests
        [NSObject cancelPreviousPerformRequestsWithTarget:self];

        [_tableView scrollToRowAtIndexPath:textFieldIndexPath atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
    }
}

- (void) scrollToOldPosition {
  [_tableView scrollToRowAtIndexPath:_topmostRowBeforeKeyboardWasShown atScrollPosition:UITableViewScrollPositionTop animated:YES];
}

- (void)_keyboardWillHide:(NSNotification*)notification {
    if (self.navigationController.topViewController == self) {
        NSDictionary* userInfo = [notification userInfo];

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
        [UIView setAnimationCurve:[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]];
        _tableView.frame = self.view.bounds;
        [UIView commitAnimations];

        [self performSelector:@selector(scrollToOldPosition) withObject:nil afterDelay:0.1];
    }
}
