UIToolbar and buttons not appearing (iOS 7)

I am trying to learn the nuts and bolts of using UIToolbar in iOS 7. To accomplish that, I used the following pre-iOS 7 code: http://www.edumobile.org/iphone/iphone-apps/using-toolbars-in-iphone/

The code works fine in iOS 6 but it seems that neither the toolbar nor its items are visible in iOS 7. Would you be so kind as to help me find a solution to the problem or point out resources that I could use to implement toolbars in iOS 7.

Thank you!

You need to explicitly show the toolbar:

[self.navController setToolbarHidden:NO];

Btw, setting the root view controller of the app should be done with UIWindow's setRootViewController:, instead of just adding the view as a subview of the window.

So your code may look like:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.

    self.rootViewController = [[MainViewController alloc] initWithNibName:nil bundle:nil];
    self.rootViewController.title = @"Main View";
    self.navController = [[UINavigationController alloc] initWithRootViewController:self.rootViewController];
    self.navController setToolbarHidden:NO];
    [self.window setRootViewController:self.navController];

    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

This is purely a subjective opinion, but edumobile.org doesn't seems to be the best website out there to learn iOS/ObjC. These courses seems outdated / with bad practices and WOT gave me a warning when entering... Nothing against them though, I didn't know this website before answering.
