Question

I have scoured the internet looking for a good tutorial or posting about having a UITableView populated with a UITextField in each cell for data entry.

I want to keep track of each UITextField and the text written within it while scrolling. The tableView will be sectioned. I have been using a custom UITableViewCell but I’m open to any method.

Also, is it possible to use the textFields as ivars?

If any of you could point me in the right direction, it would be greatly appreciated.

Thank you in advance!

To solve your problem you have to maintain an array, with some number (number of textFields you added to all cells) of objects.

While creating that array you need add empty NSString objects to that array. And each time while loading the cell you have to replace the respected object to respected textField.

Check the following code.

- (void)viewDidLoad{
    textFieldValuesArray = [[NSMutableArray alloc]init];
    for(int i=0; i<numberofRows*numberofSections; i++){
        [textFieldValuesArray addObject:@""];
    }

}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return numberofSections;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return numberofRows;
}

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

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
     cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];

     CustomTextField *tf = [[CustomTextField alloc] initWithFrame:CGRectMake(5,5,290,34)];
     tf.tag = 1;
     [cell.contentView addSubView:tf];
     [tf release];
    }
    CustomTextField *tf = (CustomTextField*)[cell viewWithTag:1];
    tf.index = numberofSections*indexPath.section+indexPath.row;
    tf.text = [textFieldValuesArray objectAtIndex:tf.index];

    return cell;
    }

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

    int index = textField.index;
    [textFieldValuesArray replaceObjectAtIndex:index withObject:textField.text];
}
