I get that it is expected that a root controller will be installed in applications at the end of an application launch error

Question

So, I read similar posts, and I think that I have everything I need. In the AppDelegate.m application, the function application: didFinishLaunchingwithoptionis looks like this:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; // Override point for customization after application launch. if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { self.viewController = [[[ViewController_iPhone alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] autorelease]; } else { self.viewController = [[[ViewController_iPad alloc] initWithNibName:@"ViewController_iPad" bundle:nil] autorelease]; } self.window.rootViewController = self.viewController; [self.window makeKeyAndVisible]; return YES; 

}

My appdelegate.h is as follows:

  @class ViewController; @interface AppDelegate : UIResponder <UIApplicationDelegate> @property (strong, nonatomic) UIWindow *window; @property (strong, nonatomic) ViewController *viewController; @end 

And finally, my main.m looks like this:

  int main(int argc, char *argv[]) { @autoreleasepool { return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); } } 

Help PLease, the application just loads a black screen, I don’t know where the problem is.

Make sure that you set the base name of the main nib file for iPhone and iPad on the tab with information about your target settings.
