After many demonstrations of the power of NSController ("Aaron, this

3!"),
I'm particularly interested by this point.
NSController(252,500) = 3;
Can it be possible to have the conversion ratio on the number of
outlet connections?
I'm assuming that Aaron was exaggerating slightly here.. :-)
In my talk I did go over a real-world case of converting the OpenUp
Preferences panel to using NSUserDefaultsController. The only reason
for the lines that exist code wise is to set up the initial default
values, and handle the "set file location" button functionality.
From the slides
(

Results
PrefsController class
Without controller - .h 61 lines /.m 346 lines
With controller - .h 30 lines / .m 80 lines
30 minutes to do
Less if I could remember the preferences keys I had used
Breakdown
PrefsController.h
All but one IBOutlet was removed (preferencesPanel)
Most of the glue code declarations were removed
PrefsController.m
removed 75% of the code in the .m
Provides initial values for defaults (was in AppDelegate)
Modified the existing file/directory selecting method
Three small target methods to call file/directory selecting method
with the correct preferences key
And you get a huge win when it comes to dealing with NSTableView
selection behaviors. I was going to code an example that did what the
controllers does using the standard methods, but didn't have time (and
it would have taken a while).
I also want to say that I appreciate Aaron's posting a follow-up here.
And he was also most gracious when asked for his opinion during my
talk.
