UITextFields in UITableView, entered values reappearing in other cells

Question

I have a UITableView with about 20 cells, in each cell there are three UITextFields. I did NOT subclass UITableViewCell, but when setting up each cell I set the textfields t

Answer 1

Just get the textfield text into Dictionary setObject by label text and again check by label Text assign the text to corresponding Textfield.. here is my code...

//In Interface
NSMutableDictionary *amounts;
amounts =[[NSMutableDictionary alloc]init];

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

static NSString *CellIdentifier = @"MoneyEntryIdentifier";
static NSString *CellNib = @"MoneyEntry";
MoneyEntryTableViewCell *cell = (MoneyEntryTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (!cell)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:CellNib owner:self options:nil];
cell = (MoneyEntryTableViewCell *)[nib objectAtIndex:0];
}

UILabel     *lblname  = (UILabel *)    [cell lblMemName];
lblname.tag =100;
UITextField *txtfield = (UITextField *)[cell textAmount];
txtfield.tag =indexPath.row;

[txtfield addTarget:self  action:@selector(textFieldDidChange:)    forControlEvents:UIControlEventEditingChanged];
lblname.text = tabledata[indexPath.row];
txtfield.placeholder = [NSString stringWithFormat:@"%ld",(long)indexPath.row];


if ([amounts valueForKey:lblname.text] != nil) {
 txtfield.text = [amounts valueForKey:lblname.text];
} else {
 txtfield.text = @"";
}

cell.selectionStyle =UITableViewCellSelectionStyleNone;
return cell;
}

 -(void)textFieldDidChange:(UITextField *)txtField
 {
 UILabel *label = (UILabel *)[txtField.superview viewWithTag:100];
 NSString *labelString = label.text;
 NSString *textFieldString = txtField.text;
 [amounts setObject:textFieldString forKey:labelString];
 }

Change the nib to your tableview cell...

The issue is that when the cell is reused (i.e. dequeueReusableCellWithIdentifier returns non-nil), the cell is returned with the existing UITextView. To maintain the uniqueness of the tags, it'll be better to remove any previous UITextField:

- (void)removeExistingTextSubviews:(UITableViewCell *)cell
{
    NSMutableArray *toRemove = [NSMutableArray array];
    // I don't know if you have non-TextField subviews
    for (id view in [cell subviews]) {
        if ([view isKindOfClass:[UITextField class]] && view.tag >= 1000) {
           [toRemove insert:view];
        }
    }

    for (id view in toRemove) {
        [toRemove removeFromSuperView];
    }
}

...

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
} else {
    [self removeExistingTextSubviews:cell];
}
//Modify cell, adding textfield with row-unique index value
cell = [self modifyCellForHoleInfo:cell atIndexPath:indexPath];
cell.accessoryType = UITableViewCellAccessoryNone; 

// Load value for textfield stored in dataArray
((UITextField *)[cell viewWithTag:1000+indexPath.row]).text = [dataArray objectAtIndex:indexPath.row];

Please note that I haven't compiled the code, but it should serve as a starting point.
