Here's the ticket: https://www.macruby.org/trac/ticket/1280 As I mentioned there, my use case isn't for a Cocoa API -- it's my own API. I'm using MacRuby to test my framework and have written a couple mock implementations in MacRuby to simplify testing. christian. On May 15, 2011, at 3:35 PM, Laurent Sansonetti wrote:
Hi Christian,
I think I only implemented Ruby -> ObjC blocks support, not the other way around :) I didn't know Cocoa was exposing APIs returning ObjC blocks yet. Could you file a ticket? I will try to get that fixed in the upcoming release.
Thanks, Laurent

Hey All,
There's plenty of documentation showing how one can use Proc objects to invoke Objective-C methods that accept block parameters, but I can't find any way to invoke an Objective-C block from within a Ruby method.
Without thinking I had assumed they'd be mapped to a Proc-like object, which I could invoke with #call:
def performOperation(operation, success:success_callback, error:error_callback) # ... result = "..." success_callback.call(result) end
But I get an error: undefined method `call' for #<__NSAutoBlock__:0x2006b6560>
