Parent and child view in Container V - ios

Question

I have a project in iOS and I am trying to modify the same to use in another project. The project is working fine but when I try and Embed the Side View Controller in a tab bar controller it is giving an error
**MFSideMenuDemoStoryboard[23760:c07] -[UITabBarController setLeftMenuViewController:]: unrecognized selector sent to instance 0x757a590
2013-06-13 10:08:51.062 MFSideMenuDemoStoryboard[23760:c07] **** * * **Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITabBarController setLeftMenuViewController:]: unrecognized selector sent to instance 0x757a590'**
i understand that there is something wrong in the Code in appDelegate .m but can't figure out
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:[NSBundle mainBundle]];
MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;
UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:#"navigationController"];
UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:#"leftSideMenuViewController"];
UIViewController *rightSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:#"rightSideMenuViewController"];
[container setLeftMenuViewController:leftSideMenuViewController];
[container setRightMenuViewController:rightSideMenuViewController];
[container setCenterViewController:navigationController];
return YES;
}
This is my storyboard

Answer 1

Your root view controller is not a MFSideMenuContainerViewController. It is a UITabBarController. If you want to use MFSideMenuContainerViewController you will want to check out the documentation: https://github.com/mikefrederick/MFSideMenu/
Here is a basic example:
UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:#"leftSideMenuViewController"];
UIViewController *rightSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:#"rightSideMenuViewController"];
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController: self.window.rootViewController
leftMenuViewController: leftSideMenuViewController
rightMenuViewController: rightSideMenuViewController];
self.window.rootViewController = container;
[self.window makeKeyAndVisible];
This will replace your existing root view controller with a MFSideMenuContainerViewController and place your old root view controller as the center view controller.

Answer 2

As you can see in the storyboard and in the exception, your root view controller is a tab bar controller, not a side menu controller.
UITabBarController has a property viewControllers which gives you access to the controllers inside the tabBarController. You want to get the controller at index 0. This means the viewController at the first tab.
Something like this should work:
UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;
MFSideMenuContainerViewController *container = tabBarController.viewControllers[0];
// check that container is actually a container and not something else
NSParameterAssert([container isKindOfClass:[MFSideMenuContainerViewController class]]);
