Question

What I am having is

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

    static NSString *CellIdentifier = @"Cell";

    cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
        cell = customCell;
        self.customCell = nil;
    }

    // Configure the cell.
    switch (indexPath.row) {
        case 0:
            cell.title.text = @"iPhone!";
            cell.date.text = @"December 25, 2009";
            cell.imageView.image = [UIImage imageNamed:@"iphone.png"];
            break;
        case 1:
            cell.title.text = @"Second Cell";
            cell.date.text = @"December 26, 2009";
            //Put in your own image. Make sure it is 120 by 100
            cell.imageView.image = [UIImage imageNamed:@""];
            break;
        default:
            break;
    }
    return cell;
}




// Override to support row selection in the table view.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSLog(@"index %d",indexPath.row);
    NSIndexPath *index = [NSIndexPath indexPathForRow:indexPath.row inSection: 0];
    NSArray *array = [NSArray arrayWithObject: index];
    cell.title.text = @"tetete";
    [self.myTable reloadRowsAtIndexPaths: array withRowAnimation: UITableViewRowAnimationFade];
}

My purpose is if you click on the a row, you will change the text of label of this row.

However, reloadRowsAtIndexPath will invoke cellForRowAtIndex and this time it will assign the old text to the uilabel

My question : how should I change so that I can change the value of the uilabel after click on the row

Answer 1

You can set value to the label in the method

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

And can access the cell by the line,

NSIndexPath * path = [NSIndexPath indexPathForRow:0 inSection:1];
        UITableViewCell * cell = [tableView cellForRowAtIndexPath:path];
