Если вы создаете универсальный шаблонный проект, вы можете проверить код, созданный для этой версии. Например:
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
MasterViewController *masterViewController = [[MasterViewController alloc] initWithNibName:@"MasterViewController_iPhone" bundle:nil];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];
self.window.rootViewController = self.navigationController;
} else { // iPad
MasterViewController *masterViewController = [[MasterViewController alloc] initWithNibName:@"MasterViewController_iPad" bundle:nil];
UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];
PSGameViewController *detailViewController = [[PSGameViewController alloc] initWithNibName:@"DetailViewController_iPad" bundle:nil];
UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController:detailViewController];
self.splitViewController = [[UISplitViewController alloc] init];
self.splitViewController.delegate = detailViewController;
self.splitViewController.viewControllers = [NSArray arrayWithObjects:masterNavigationController, detailNavigationController, nil];
self.window.rootViewController = self.splitViewController;
}
[self.window makeKeyAndVisible];
return YES;
}
или от tableView:didSelectRowAtIndexPath:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
if (self.detailViewController == nil) {
self.detailViewController = [[PSGameViewController alloc] initWithNibName:@"PSGameViewController_iPhone" bundle:nil];
}
self.detailViewController.model = selectedModel;
[self.navigationController pushViewController:self.detailViewController animated:YES];
self.pushedIndexPath = indexPath;
} else { // iPad
self.detailViewController.model = selectedModel;
}
