Scroll custom UITableViewCell to right above keyboard?

Currently I have a UITableView with custom cells and in each cell there is a UITextField, the problem is that sometimes the UITextField is covered by the UIKeyboard.

So right now I have the Y coordinate for the UIKeyboard and my UITableView is functioning properly with the cells.

So pretty much how can I use that Y coordinate (float), in order to scroll my UITableView to that Y coordinate plus the height of the cell in order to get it right above my UIKeyboard?

Also when I the keyboard hides, how would I reset the UITableView to its normal position that it was in?

Any advice would be appreciated!

Thanks!

CustomCell *cell = (CustomCell*)[[thetextField superview] superview];
    CGRect cellRect = [cell convertRect:cell.frame toView:self.view];
    float bottomCell = cellRect.origin.y - cellRect.size.height;
    if (bottomCell >= keyboardY) {
        NSIndexPath *indexPath = [thetableView indexPathForCell:cell];
        [thetableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
    }

UITableView adjust itself whenever the keyboard is displayed.

However, it won't do it if you didn't set the UITableViewCellSelectionStyle of your custom cell to UITableViewCellSelectionStyleNone.

i solved by using the below code.

    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];

One or the other of UITableView's

- (void)scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated;
- (void)scrollToNearestSelectedRowAtScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated;

I'm guessing that control isn't getting into the if statement. Consider skipping the y-coordinate check in favor of just scrolling the table view regardless of where it is.

CustomCell *cell = (CustomCell *)[[theTextField superview] superview];
NSIndexPath *indexPath = [theTableView indexPathForCell:cell];
[theTableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];

OK, if you're sure it's getting called, then make sure your indexPath isn't nil, which may happen if cell isn't in the tableView or if it's not a cell.
