Answer 1

To programatically add a third view controller to a standard tabbed iOS application:

1. Go to File -> New -> File, select Objective-C class, enter "ThirdViewController" for the class, select "UIViewController" under the subclass of option. Check "With XIB for user interface."

2. Go to the new XIB and add a label or other objects of your choice.

3. In AppDelegate.m import your new class by adding #import "ThirdViewController.h" to the file imports.

4. Still in AppDelegate.m, in the didFinishLaunchingWithOptions method create a UIViewController object for the third view (follow the format for the first two), and add the third view controller to the tabbarcontroller two lines below: self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, viewController3, nil];.

5. Save and run your project.

The didFinishLaunchingWithOptions method should look like this when finished:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
    UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
    UIViewController *viewController3 = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, viewController3, nil];
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];
    return YES;
}
