Objective-C: Transitioning from UIImagePickerController to a second UIViewController
===

Still feeling pretty green in Objective-C - building my first "real" project and hit an architectural snag early on..

I'd like to present my views and navigation in a fully 'custom' environment - e.g. something where I hide all of the built-in UI controls. One specific example (as in the title): moving from a 'main' view directly to a UIImagePickerController, and then right from the UIImagePickerController to a new third view.

Here are the three primary view controllers I'm working with:

 - **MainViewController** (custom subclass of UIViewController, contains my main Nav and is in general my primary or 'parent' controller)
 - **ImageEditViewController** (custom subclass of UIViewController wherein I overlay some controls on top of a stored image)
 - **UIImagePickerController** (built-in Apple class)

There are a couple of approaches I can image for this (but I can't figure out how to do either one):

 1. **Use a UINavigationController or UITabBar implementation**, but somehow hide the system UI controls and implement my own. I am blocked on this approach because - simply - *I don't know how to hide the system UI controls*.
 2. **Call controller-to-controller or view-to-view transitions manually** at specific points in the code. I sort of prefer this method but I can't figure out the best 'approach' to instantiating and managing and transitioning between my controllers. Example of things I don't know: how do I call a second view controller from my main view controller? How do I call a third view controller directly from the second? (Or at least transition to the third directly!)

I assume there is an easy solution here; just something I haven't learned yet about managing views and view controllers outside of Apple's helper classes.
