No problem at all.

Yes, please do.

Ah! Looks good. I will try it out.

I've attached a patch to this message that extends the base Ruby-Cocoa  
bridge class methods. addRubyMethod_withType allows creation of an  
actual ObjC method corresponding to a ruby method. This means that  
key-value coding will be able to find the actual method when it does a  
lookup.

This could be used to define real accessor methods (therefore avoiding  
the valueForUndefinedKey hook), or for implementing array accessors  
(which have no such hook). For example:

     def kvc_array_accessor(*args)
       kvc_accessor(*args)
       args.each do |v|
         n = v.to_s
         n[0..0] = n[0..0].upcase
         self.addRubyMethod_withType("countOf#{n}".to_sym,"i4@8:12")
          
self.addRubyMethod_withType("objectIn#{n}AtIndex_".to_sym,"@4@8:12i16")
          
self.addRubyMethod_withType("insertObject_in#{n}AtIndex_".to_sym,"@4@8: 
12@16i20")
          
self.addRubyMethod_withType("removeObjectFrom#{n}AtIndex_".to_sym,"@4@8: 
12i16")
         # ...

I've attached an updated version of ObjcID that has the full  
implementation of this method.

Thanks
