Newbie: IB bindings versus programmatic bindings

Hello all.

I'm new to cocoa programming, and my first project relies heavily on 
bindings. I've set them up in IB, which seemed like a good idea after 
reading the "getting started" manuals 'n stuff.

However, now that I'm getting deeper into the project, it seems like IB 
hides everything away if I want to expand on it. Say I want to add a new 
custom control and I want to bind to the existing values in the app. 
They're simply not there, or they're hidden away in some controller. It 
seems like I'm better off doing things programmatically after all.

What do you seasoned cocoaders do out there? Use IB or write your code 
by hand?

I'm on xCode 3.0 and MacOS 10.5.2 by the way, if it makes any difference.


Best regards,
Jens
