How to use generic (NSObject) controller with subviews of a UIViewController?
- by wanderlust
I have a UIViewController that is loading several subviews at different times based on user interaction. I originally built all of these subviews in code, with no nib files. Now I am moving to nib files with custom UIView subclasses.
Some of these subviews display static data, and I am using loadNibNamed:owner:options: to load them into the view controller. Others contain controls that I need to access.
I (sort of) understand the reasons Apple says to use one view controller per screen of content, using generic controller objects (NSObjects) to manage subsections of a screen.
So I need a view controller, a generic controller, a view class and a nib. How do I put this all together?
My working assumptions and subsequent questions:
I will associate the view class with
the nib in the 'class identity' drop
down in IB.
The view controller will coordinate
overall screen interactions. When
necessary, it will create an instance
of the generic controller.
Does the generic controller load the
nib? How?
Do I define the outlets and actions
in that view class, or should they be
in the generic controller?
How do I pass messages between the
view controller and the generic
controller?
If anyone can point me to some sample code using a controller in this way, it will go a long way to helping me understand. None of the books or stackoverflow posts I've read have quite hit the spot yet.
