Question

I have placed UITextField over each UITableView cell. While scrolling the UITableView cell the text over the UITextField is getting lost. What can I do to prevent this?

You need to get track of an NSMutableArray which stores the text field values. Make the initial values @””. When you insert the text field into the cell, get the value from the appropriate value in the array.

If the text field exits, do something like this to store your text field values in the array:

    -(BOOL)textFieldShouldReturn:(UITextField *)textField 
    {
    UITableViewCell *cell=(UITableViewCell *)textField.superview;
    NSIndexPath *indexPath = [table indexPathForCell:cell];

    NSMutableArray *rows=[sectionArray objectAtIndex:[indexPath section]];
    NSString *string=[rows objectAtIndex:indexPath.row];
    string=textField.text;
    [[sectionArray objectAtIndex:[indexPath section]]replaceObjectAtIndex:[indexPath row] withObject:string];
    [textField resignFirstResponder];
    return YES; }

    - (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *myCellId= @"myDateCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:myCellId]; 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault 
                                  reuseIdentifier: myCellId]; 

    CGRect textFieldFrame;
    CGRect labelFrame;
    labelFrame = CGRectMake(cell.frame.origin.x+45, cell.frame.origin.y+3, labelWidth, cell.bounds.size.height-5);
    textFieldFrame = CGRectMake(cell.frame.origin.x+labelWidth+15, cell.frame.origin.y+12 ,cell.
    UILabel *label = [[UILabel alloc]initWithFrame:labelFrame];

    UITextField *textField = [[UITextField alloc]initWithFrame:textFieldFrame];
    textField.keyboardType=UIKeyboardTypeNumberPad;
    textField.delegate = self;
    textField.text = [[sectionArray objectAtIndex:[indexPath section]]objectAtIndex:[indexPath row]];


    [cell addSubview:label];
    [cell addSubview:textField];

    cell.selectionStyle = UITableViewCellSelectionStyleNone;
    return cell;
}
