Hi all. I am VERY VERY new to iPhone development, and I need to get my head around the abstract objects involved. I am struggling like crazy with "RootViewController" - what is one?.
Can anybody point me to a n00bs tutorial, which includes a diagram and pictures... yes, I work best with schematic

as I am SO SO out of my depth here!. I've got all these floating Xcode windows... one says "View - Loaded From "RootViewController"
Another, has a tree of items, a few of which I am familiar with, but includes "Navigation Controller" etc... I am SO lost here

. Please help - I admit, unashamedly, that I am the n00best of them ALL!.
Thanks - oh, and please speak slowly - I am VERY noobish!!
