updated ti.dynamiclib.js

ti.dynamiclib.js

/**
 * Ti.DynamicLib
 * @abstract Support embedded binaries (aka dynamic libraries) in Titanium modules and Hyperloop.
 * @version 1.1.0
 * 
 * Install: 
 * 1) Search and replace '../../src/<YourFramework>.framework' with your framework location.
      The path is relative to the `build/iphone` directory.
 * 2a) For classic modules: 
 *       - Add 'LD_RUNPATH_SEARCH_PATHS=$(inherited) "@executable_path/Frameworks" $(FRAMEWORK_SEARCH_PATHS)'
 *         to your module.xcconfig
 *       - Place this file (ti.dynamiclib.js) in `<your-module-ios-root>/hooks`
 *    
 * 2b) For Hyperloop (will be automated in future Hyperloop versions - Follow TIMOB-23853): 
 *       - Add the above to the `hyperloop.ios.xcodebuild.flags` object of your appc.js
 *       - Place this file (ti.dynamiclib.js) in `<your-projecz-root>/plugins/ti.dynamiclib/hooks`
 *
 * 3) Some frameworks include Simulator architectures ("fat libraries"). Those frameworks usually provide a 
 *    script to strip the unused frameworks for distribution, e.g. `strip-framework.sh`. If you use such a 
 *    framework, adjust the path of the variable `scriptPath`, otherwise `null` it to skip the build script phase.
 *
 * 4) That's it! You can check an example integration in the Ti.Flic module (https://github.com/hansemannn/ti.flic)
