How to scroll cutsom UITextFieldCell above UIKeyboard - ios

Question

I have a UITableView that uses a custom UITableViewCell. My UITableVewCell has two textfields inside it, which I have added a tag to in my main ViewController that holds the UITableView which houses my custom UITableViewCell.
So this is the code inside my tableView:cellForRowAIndexPath:
static NSString *CellIdentifier = #"Cell";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[CustomFCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
NSString *widthString = [currentFDictionary objectForKey:#"MM"];
if ((NSNull *) widthString != [NSNull null]) {
cell.widthTexField.text = widthString;
cell.widthTexField.tag = indexPath.row;
} else {
cell.widthTexField.text = #" ";
}
NSString *heightString = [currentFDictionary objectForKey:#"NM"];
if ((NSNull *) heightString != [NSNull null]) {
cell.heightTextField.text = heightString;
cell.heightTextField.tag = indexPath.row;
} else {
cell.heightTextField.text = #" ";
}
return cell;
I would like to know how to then use this .tag to scroll the UITableViewCell above the UIKeyboard that will now be shown in the view.
Anyhelp would be greatly apprecited.

A simple way i can think of is by using the -scrollToRowAtIndexPath:atScrollPosition:animated:
Set the delegate on the UITextField objects.
cell.widthTexField.delegate = self;
//...
cell.heightTextField.delegate = self;
Now, use -textFieldShouldBeginEditing: delegate method in this manner:
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
NSIndexPath *currentSelectedIndexPath = [self.tableView indexPathForSelectedRow];
[self.tableView scrollToRowAtIndexPath:currentSelectedIndexPath
atScrollPosition:UITableViewScrollPositionTop
animated:YES];
}
//NOTE: this way we don't really need to work with the textField tag per se
//(unless you are using it elsewhere as well)
//Instead, we work with the entire cell and scroll it to the desired position
this may not be perfect since i haven't tested it here but it's the general idea
