UINavigation in iPhone Example Code

If you've created custom button and on touch event navigation is not done then you should put this code in your app delegate file.

AppDelegate.m 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    // Override point for customization after application launch.

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

        self.viewController = [[CoRoViewController alloc] initWithNibName:@"CoRoViewController" bundle:nil];

    } else {

        self.viewController = [[CoRoViewController alloc] initWithNibName:@"CoRoViewController" bundle:nil];

    }

    

UINavigationController *contrl = [[UINavigationControlleralloc]initWithRootViewController:self.viewController];

    self.window.rootViewController = contrl;

    [self.window makeKeyAndVisible];

    return YES;

}
