如何根据表视图单元格的详细文本标签，将segue设置为与表视图控制器不同的视图控制器？

Question

I am just beginning to learn objective-c and programming in general, and I am really stuck on this issue. I am using storyboards to create an app that keeps scores for different types of games. I have a master view controller that is a table view and it has prototype cells with detail labels. There is an AddKeeperViewController that allows the user to input player names and the game type. The game type is then used as the detail label for the prototype cells.

I want to then have each cell push to a different view controller, depending on what the detail text label is. I only have 2 game types at the moment, I know I need to set up logic in tableView didSelectRowAtIndexPath that will choose which segue to take. I set up my segues from the view controller, not the cells, and they each have a unique identifier. I just don't know how to set up my if statements to use the gameType as the deciding factor for which segue to take.

Here is some of my code from my MasterViewController.m file:

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    scoreKeeper *keeperAtIndex = [self.dataController objectInListAtIndex:indexPath.row];

    [[cell textLabel]setText:keeperAtIndex.name];
    [[cell detailTextLabel] setText:keeperAtIndex.gameType];

    return cell;
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if(cell.detailTextLabel) {
          //statement
    }
    if ([[segue identifier] isEqualToString:@"ShowKeeperDetails"]) {
        MADDetailViewController *detailViewController = [segue destinationViewController];

        detailViewController.keeper = [self.dataController objectInListAtIndex:[self.tableView indexPathForSelectedRow].row];
    }
}

Answer 1

It seems like you're on the right track. However, I think you're waiting a bit too long to choose which segue to take. Perhaps something like this would work for you:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

    if ([cell.detailTextLabel.text isEqualToString:@"TEXT"]) 
    {
        [self performSegueWithIdentifier:@"segueTypeOne" sender:nil];
    } 
    else 
    {
        [self performSegueWithIdentifier:@"segueTypeTwo" sender:nil];
    }
}

您还可以创建不同单元的原型，每个原型都与导致不同视图的不同segue连接，然后使用正确的原型在dequeueReusableCellWithIdentifier获取单元。
