MacRuby and NSError
Just a note for other people that might be cracking their heads trying to meld MacRuby and NSError ** parameters. The answer was already sitting on my computer, I just never through to look at the MacRuby Core Data XCode templates, but that’s beside the point. For those of you searching, you just need to do the following.
error = Pointer.new_with_type('@')
unless managed_object_context.save(error)
NSLog error[0].inspect
NSApplication.sharedApplication.presentError(error[0])
end
The NSLog error[0].inspect
will output #<NSError:0x80057a640>
. Exactly
what we want.
