You mean Ruby calling Objective-C?
Once the MacRuby runtime is initialized, you can access all your Objective-C
objects from Ruby. For example, if you have an Objective-C class named Foo, you
can do `Foo.new', etc.
Another possibility is to pass your Objective-C objects to a Ruby method by
using -[NSObject performRubySelector:].
ruby:
class Foo
def test(o)
o.something
end
end
objc:
MyObject *o = [MyObject new]; // where o responds to -something
MacRuby *runtime = [MacRuby sharedRuntime];
id foo_obj = [runtime evaluateString:@"new Foo"];
[foo_obj performRubySelector:@selector(test:) withArguments: o, NULL];
