Is there a way to access instance variables defined in an Objective-C class from a Ruby extension? I'm porting some of Apple's example code to MacRuby as a learning experience and would like to do so incrementally. Porting the code one class at a time works fine, but for some of the larger classes I'd like to port them a few methods at a time. Here's an example of what's happening --- Example.h --- @interface Example : NSObject { NSString *instVarA; NSString *instVarB; } - (NSString *)methodA; @end --- Example.m --- #import "Example.h" @implementation Example - (id)init { if (self = [super init]) { instVarA = @"instVarA"; instVarB = @"instVarB"; } return self; } - (NSString *)methodA { return instVarA; } @end --- Example.rb --- class Example def methodB @instVarB end end Then at runtime, when I execute the following... example = Example.alloc.init puts example.methodA.inspect puts example.methodB.inspect .. I get "instVarA" nil How do I access InsVarB from Ruby? Thanks, Ed
