Programmatically adding a UITableView - how do I set a reuse identifier for cells?

I have a UIViewController that at some point produces a UITableView, and when it does, I just launch an instance of the TableView instance and add it to the view, but I'm not sure how to handle the cell de-increment to add to the View; I need a reuse id, but I'm not sure how to set it.

What should I do in this method?

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];

    return cell;
}

Use method initWithStyle:reuseIdentifier

  • check if exists cell
  • If this is not the case, you need to initialize it.

the code

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath (NSIndexPath*)indexPath 
{
    static NSString *cellIdentifier = @"wot";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];

    if (!cell)
        cell = [[UITableViewCell alloc] initWithStyle: someStyle reuseIdentifier: cellIdentifier];

    return cell;
}

,

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *MyIdentifier = @"MyReuseIdentifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault  reuseIdentifier:MyIdentifier]];
    }
    Region *region = [regions objectAtIndex:indexPath.section];
    TimeZoneWrapper *timeZoneWrapper = [region.timeZoneWrappers objectAtIndex:indexPath.row];
    cell.textLabel.text = timeZoneWrapper.localeName;
    return cell;
}
