[Rubycocoa-talk] More on Calling Ruby From Objective-C

[David B. <dba...@gm...>]

Hello.  I am attempting to use a ruby library in an Objective-C/Cocoa  
application.  I am having some difficulty figuring out calling  
conventions.  For example, if the ruby class has the class initializer:

def initialize(empid = "", key = "", manid = "")

How do I properly initialize this from objective-c?
I was doing:
     Class helperClass = NSClassFromString(@"EmpClass");
     id helperInstance = [[helperClass alloc] init];

I am also wondering how I accesses my_url defined in the ruby class  
such as:

   class MyRubyClass < OSX::NSObject

     @@my_url = 'http://mywebsite.com'
    cattr_accessor :my_url
  end


and while I am asking I have a method defined as
     def employees(opts = {})

how do I call that with the helperInstance in obj-c?

Is there some reference material somewhere that would explain how to  
call ruby methods from objective-c somewhere?  Most of the information/ 
examples I see assume your entire program is written in ruby but using  
the cocoa framework.

Thank you.
