iOS Storyboard?

Question

Objective-C

Hello everyone :)
Started coding for iOS in XCode 4.2 and decided to start with storyboard. At first glance, everything is very simple and beautiful.
I encountered such a problem - when switching views, these views are unloaded from memory and, accordingly, you cannot access these objects from the outside.
Is there any way to disable the automatic unloading of views from memory when switching between them? Or how can you implement the exchange of information between objects (so far, the crutch is delegate variables)?

Answer 1

view should not store data, but only display. Somehow more specifically the situation would be formulated.

Answer 2

MVC keyword.
