Objective-C Services for Mac

From Scotland Software:

ObjCServices provides 6 system Services which convert Objective-C instance variable declarations into accessor prototypes and implementations, saving a lot of typing.
The services can convert ivars to implementations, ivars to prototypes, or prototypes to implementations, and in each case you have the choice of replacing the selection or putting the new prototypes/implementations on the clipboard.
Both "get" and "set" accessor methods are catered for, and the services deal sensibly with scalar data types as well as pointers to objects. "Set" accessors use the "retain then release" style.
Full source code is included in the download, so the services can be fully customized with the Mac OS X Developer Tools.
