What will happen, is when you compile the main Objective C File, Main.m, it'll compile all the other Objective C files into the binary executable, that will eventually run your rb_main.rb file. It'll give all the access of your Objective C libraries that you wrote, right within your application. hth, Mario > Thanks, > > Shaun > > > > > On 2010-10-19, at 10:12 PM, Mario Steele wrote: > > Hello Shaun, > > On Wed, Oct 20, 2010 at 12:00 AM, Shaun August <sh...@eoslightmedia.com>wrote: > >> Hi Robert, >> >> Thanks!
