title: naming conventions - uinavigationcontroller and root view
body: <p>This may be the silliest question i have ever asked here, but i just can't seem to understand this. I am new to xcode and iOS development, and these days trying to learn how uinavigtioncontroller works. In all the examples and tutorials that i see (none of which could help me btw...maybe b/c of the new xcode?), there is always a mention of a RootViewController class. Now, when I open a new view based app project, i immediately get the app delegate class and another object called: MyProjectViewController. So my question is - is this RootViewController that everyone are talking about IS the MyProjectViewController that is created for me automatically? OR do they open a new class and call it RootViewController? OR do they just change its name from MyProjectViewController to RootViewController? (or something else...:))</p>
  
  <p>Thanks for the help! </p>
