Initialize a MBPullDownController with a front and back view controller, than add the controller to your view hierarchy.

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

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

self.window.rootViewController = [self setUpViewControllerHierarchy];

[self.window makeKeyAndVisible];

return YES;

}

- (UIViewController *)setUpViewControllerHierarchy {

MBImagesViewController *front = [[MBImagesViewController alloc] init];

MBSettingsController *back = [[MBSettingsController alloc] init];

MBPullDownController *pullDownController = [[MBPullDownController alloc] initWithFrontController:front backController:back];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:pullDownController];

navigationController.navigationBarHidden = YES;

return navigationController;

}

The front controller's view must be a UIScrollView subclass.
