New description:
When using forwardingTargetForSelector: to create a wrapper class in
ObjC, it does not work in MacRuby.
It's kind of a complicated setup, so I've created a minimal-ish project in
github containing ObjC and MacRuby code to illustrate the problem. It's
here:
http://github.com/diffengr/macruby_forwarding_invocation_example
That contains an XCode project and a rakefile. It has the ObjC classes
Candy and CandyWrapper, and they both have the NSString* property flavor.
CandyWrapper declares that property @dynamic, and forwards it to Candy.
Here's the code that works in ObjC.
{{{
Candy* rootBeerCandy = [[Candy alloc] init];
rootBeerCandy.flavor = @"Root Beer";
CandyWrapper* rootBeerWrapper = [[CandyWrapper alloc]
initWithCandy:rootBeerCandy];
NSLog(@"Candy#flavor \"%...@\", Wrapper#flavor \"%...@\"",
rootBeerCandy.flavor,
rootBeerWrapper.flavor);
}}}
If you load and run the xcode project in this directory, you'll get this
output:
{{{
NSLog[...] <CandyWrapper: 0x104fb0> forwarding flavor to <Candy:
0x103380>
NSLog[...] Candy#flavor "Root Beer", Wrapper#flavor "Root Beer"
}}}
Here's that same code instantiated in MacRuby, from candy_test.rb:
{{{
rootBeerCandy = Candy.alloc.init
rootBeerCandy.flavor = 'Root Beer'
rootBeerWrapper = CandyWrapper.alloc.initWithCandy rootBeerCandy
puts "Candy#flavor #{rootBeerCandy.flavor}, Wrapper#flavor
#{rootBeerWrapper.flavor}"
}}}
You can run this with "macrake test" in the project directory, and it will
give (among other things):
{{{
candy_test.rb:7:in `<main>': undefined method `flavor' for
#<CandyWrapper:0x8000aa2a0> (NoMethodError)
rake aborted!
}}}
