Hi Laurent,
Thanks for the help. Did you mean to set the context ivar on the
observer or on the subject? Wouldn't setting it on the observer
result in the last registration 'winning' if the observer is watching
more than one subject?

Hi Edward,
Context arguments in Objective-C are generally void pointers, which
makes them hard to use in Ruby. Also, since we run in Objective-C GC
mode, objects could potentially be collected since contexts do not
set up AFAIK write barriers.
I would recommend to set up an instance variable on your observer
instead (and pass nil as the context).
observer.instance_variable_set(:@context, your_context)
And later in your observer method, retrieve the ivar.
Laurent
