embed multiple view controller in one window

Question

I want to have a View which contains more than one view. see the below image:

as you see pageController controls page navigation and provide before and after viewController (page).

pageContentController displays text and process them.

soundPlayer manages playing related sound

I can have all of them in one controller, but my controller must do a lot of tasks and managing it will be hard task. as it disobey light view controller. and decrease its cohesion. so I wanted to know how can I accomplish this please explain in details.

Answer 1

thanks for your detailed answers. your answers clarified me. what I did:

I added SoundPalyerVC as child of PageContentVC

SoundPlayerVC *soundPlayer = [[StoryViewController alloc] initWithStory:self.storyManagedObject];
[self addChildViewController:soundPlayer];
[self.view addSubview:soundPlayer.view];
[soundPlayer didMoveToParentViewController:self];
soundPlayer.view.frame = CGRectMake(0, self.view.frame.size.height-soundPlayer.view.frame.size.height, 320, soundPlayer.view.frame.size.height);

that was so easy. now my codes are separated.
