Disabling automatic scrolling of UITableView when editing UITextField inside UITableViewCell

The autoscroll-behavior is located in the UITableViewController functionality.

To disable the automatic scrolling I found two ways:

1. Use instead of the UITableViewController simply a UIViewController - set the datasource and delegate on your own.
2. Override the viewWillAppear method and don't call [super viewWillAppear: animated]

With both solution you disable not only the Autoscroll, but also some other nice but not essential features, that are described in the overview of Apple´s class reference:

https://developer.apple.com/documentation/uikit/uitableviewcontroller

Define properties for your UITableViewController:

@property (nonatomic) BOOL scrollDisabled;
@property (nonatomic) CGFloat lastContentOffsetY;

Before you call becomeFirstResponder:

// Save the table view's y content offset 
lastContentOffsetY = tableViewController.tableView.contentOffset.y;
// Enable scrollDisabled
scrollDisabled = YES;

Add the following code to your table view controller:

-(void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    if (self.scrollDisabled) {
        [self.tableView setContentOffset:CGPointMake(0, lastContentOffsetY)];
    }
    ...
}

After you call resignFirstResponder, set scrollDisabled = NO.

You can do the following:

- (void)registerForKeyboardNotifications
{
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillShow:)
                                                 name:UIKeyboardWillShowNotification object:nil];

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

- (void)unregisterForKeyboardNotifications
{
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidShowNotification object:nil];
}

- (void)keyboardWillShow:(NSNotification *)notification
{
    self.tableView.scrollEnabled = NO;
}

- (void)keyboardDidShow:(NSNotification *)notification
{
    double delayInSeconds = 0.3;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
            self.tableView.scrollEnabled = YES;
    });
}

Then implement this UIScrollViewDelegate method

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    if (! self.tableView.scrollEnabled)
        [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForItem:0 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:NO];
}

!!! But be warned, that if the user taps in a location in the UITextField that will be covered by the Keyboard, then it won't scroll.

From my point of view, the best thing to do is to make sure that all the cells from top to then one with the UITextField included, will be visible when then Keyboard will show.
