title: UiSplitViewController App without storyboards
body: <p>I am new to iOS development and need a bit of help. I have searched high and low and cannot find the answer. It's more like I don't understand what is happening. My issue is, I am trying to code a Master-Detail App without using storyboards. This helps me get a better understanding of how ViewControllers are managed and handled. I am trying to present the DetailViewController after an item is selected in a tableView in the MasterViewController on iPhone. On iPad it works well because both views are side by side.</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
  
      //Pass data to detailViewController
      if ([_detailDelegate respondsToSelector:@selector(item:selectedAtIndexPath:)]) {
  
              [_detailDelegate item:[[BNRItemStore sharedStore] findItemAtIndex:indexPath.row] selectedAtIndexPath:indexPath];
      }
  
      if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone ) {
  
          // show DetailViewController
  
  
          NSArray *viewControllers = self.splitViewController.viewControllers;
  
          UINavigationController *detailNavigationViewController = [viewControllers objectAtIndex:1];
  
          [self showDetailViewController:detailNavigationViewController sender:nil];
  
      }
  
  
  }
  </code></pre>
  
  <p>In a storyboard the selected ViewCell has a <code>show detail segue</code> to the detailViewController. How can I achieve the same thing without using storyboards?</p>
  
  <p>My AppDelegate code for a better picture</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // Override point for customization after application launch.
  
  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  
  UISplitViewController *splitViewController = [[UISplitViewController alloc] init];
  
  self.window.rootViewController = splitViewController;
  
  
  UINavigationController *masterNavigationController = [[UINavigationController alloc]init];
  UINavigationController *detailNavigationController = [[UINavigationController alloc]init];
  
  
  MasterTableViewController *masterTableViewController = [[MasterTableViewController alloc] init];
  DetailViewController *detailViewController = [[DetailViewController alloc] init];
  
  masterTableViewController.detailDelegate = detailViewController;
  detailViewController.masterDelegate = masterTableViewController;
  
  
  masterNavigationController.viewControllers = @[masterTableViewController];
  detailNavigationController.viewControllers = @[detailViewController];
  
  [splitViewController setViewControllers:@[masterNavigationController,detailNavigationController]];
  
  
  [self.window makeKeyAndVisible];
  
      return YES;
  }
  </code></pre>
  
  <p>Thanks.</p>
