My application is one of several front-ends to a shell-script based

front-end uses resources from a NIB-file, they need to be provided by
the back-end at runtime.
Obviously you have to use bindings where titles of each of you
controls need to be bound to a controller
object which could be a kind of facade to your strings that come from
your back-end.
Does this mean that in my controller object I need to have a unique
method or instance variable for each string that I want to localize? I
was kind of hoping to find something a little less verbose.
If possible, I'd like to avoid having to manually query for each
internationalized string in code. I'm a Cocoa newbie, so maybe there is
something obvious that I'm missing, but it looks like unless I can pass
an argument to a binding, I'm basically out of luck.
As I said, write a facade which hides all the details as how the title
strings are generated. Have clean
KVC compliant methods to return those titles. And in NIB bind your
controls to appropriate keys
governed by the KVC compliant methods. Read more on KVC-KVO :
http://developer.apple.com/documentation/Cocoa/Conceptual/CocoaBindings/CocoaBindings.html
The code that generates the strings is already well abstracted, I guess
I should have said "I'd like to avoid having to implement a unique
method for every string". What I would like to do is bind all of my
controls to the same key (i.e. controller.getTitle) and pass an argument
when calling the method associated with the key, but I'm pretty sure
this isn't possible. If there is a way to accomplish this, or some other
clever way to accomplish my end goal, I'm all ears.
However there would be a problem where localized strings may have
different sizes in different languages and
you will have to take care that your controls are properly resized to
fit the title.
I understand this issue and will deal with it accordingly.
Thank you for your reply and help,
