[Rubycocoa-talk] passing args from ObjC to Ruby

[Motohiro T. <mo...@gm...>]

Hi,

While writing QuartzComposer CustomPatch with RubyCocoa, I'm in
trouble with passing arguments from Objective-C code to Ruby.
How can I pass more than one arguments to Ruby code from Objective-C code ?


Objective-C code:

  - (BOOL)execute:(id)fp8 time:(double)fp12 arguments:(id)fp20 {

    Class helperClass = NSClassFromString(@"CustomRubyPatch");
    rubyobj_ = [[helperClass alloc] initWithQCPatch:self];

    [rubyobj_ execute:fp8 time:fp12 arguments:fp20];
    return YES;
  }

and Ruby code:

  def execute(fp8, time, arguments)
    @otport.setStringValue @inport.stringValue.gsub(/Objective-C/, "Ruby")

    true;
  end

when [rubyobj_ execute:...] is invoked at runtime, an exception is
raised ("selector not recognized").

thanks,
