As part of my iPhone work I've built yet another Objective-C bridge.
It can be found within ftp://ftp.smalltalkconsulting.com/experimental/ The required Smalltalk code for the basic logic, the SUnits, and the Plugin generation can be loaded from http://www.squeaksource.com/ObjectiveCBridge2.html The additional pieces required to build the plugin are found within the iSqueak SVN tree. http://svn.isqueak.org/vm/
Using aregular 3.8.18b4U macintosh carbon VM with the ObjectiveCBridge installed means you can invoke.
testRetainCount | classOop instance1 count |
classOop := ObjectiveCObject findClassName: 'NSObject'. instance1 := classOop new. count := instance1 retainCount. self should: [count = 1]. instance1 retain. count := instance1 retainCount. self should: [count = 2]. instance1 release. count := instance1 retainCount. self should: [count = 1].
People are welcome to confirm that it works, although it is compiled for ppc and i386 (32bit) I have not yet tested on ppc.
This plugin was also installed for the currently shipping iPhone VM 1.05b3, however there seems to be a problem where resolving the method signature object isEqualTo: for usage between two instances of NSObject returns nil. But only on an ipod touch or iPhone not in the Simulator, or running as an os-x application.
