I have a UITextField in a table view on a UIViewController (not a UITableViewController). If the table view is on a UITableViewController, the table will automatically scroll to the textField being edited to prevent it from being hidden by the keyboard. But on a UIViewController it does not.

I have tried for a couple of days reading through multiple ways to try to accomplish this and I cannot get it to work. The closest thing that actually scrolls is:

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

// SUPPOSEDLY Scroll to the current text field

CGRect textFieldRect = [textField frame];
[self.wordsTableView scrollRectToVisible:textFieldRect animated:YES];

}

However this only scrolls the table to the topmost row. What seems like an easy task has been a couple of days of frustration.

I am using the following to construct the tableView cells:

- (UITableViewCell *)tableView:(UITableView *)aTableView
    cellForRowAtIndexPath:(NSIndexPath *)indexPath {

NSString *identifier = [NSString stringWithFormat: @"%d:%d", [indexPath indexAtPosition: 0], [indexPath indexAtPosition:1]];

UITableViewCell *cell = [aTableView dequeueReusableCellWithIdentifier:identifier];

    if (cell == nil) {

        cell = [[[UITableViewCell alloc] 
        initWithStyle:UITableViewCellStyleDefault 
        reuseIdentifier:identifier] autorelease];

        cell.accessoryType = UITableViewCellAccessoryNone;

        UITextField *theTextField = [[UITextField alloc] initWithFrame:CGRectMake(180, 10, 130, 25)];

        theTextField.adjustsFontSizeToFitWidth = YES;
        theTextField.textColor = [UIColor redColor];
        theTextField.text = [textFieldArray objectAtIndex:indexPath.row];
        theTextField.keyboardType = UIKeyboardTypeDefault;
        theTextField.returnKeyType = UIReturnKeyDone;
        theTextField.font = [UIFont boldSystemFontOfSize:14];
        theTextField.backgroundColor = [UIColor whiteColor];
        theTextField.autocorrectionType = UITextAutocorrectionTypeNo;
        theTextField.autocapitalizationType = UITextAutocapitalizationTypeNone;
        theTextField.clearsOnBeginEditing = NO;
        theTextField.textAlignment = UITextAlignmentLeft;

        //theTextField.tag = 0;
        theTextField.tag=indexPath.row;

        theTextField.delegate = self;

        theTextField.clearButtonMode = UITextFieldViewModeWhileEditing;
        [theTextField setEnabled: YES];

        [cell addSubview:theTextField];

        [theTextField release];


}

return cell;
}

I suspect I can get the tableView to scroll properly if I can somehow pass the indexPath.row in the textFieldDidBeginEditing method?

Any help is appreciated.
