With latest Titanium Studio 1.0.8 update and its latest SDK 1.8.1, it is now easier to create Titanium iOS module and packaged into Titanium mobile apps. I am able to code the iphone torch controller (flash light) in Objective-C and compiled into module and invoked from Titanium JavaScript API.
Just to remember to change the Apps Project release to use armv7 (standard).
Last three weeks I tried to do the same thing in older version of Titanium Studio but I failed to make it even I followed the completed steps for manually creating module skeleton templates using command utility tool.
The latest Titanium Studio 1.0.8 Update really improve module packager process.
