MacRuby for Fun and Profit
6 likes•1,241 views
MacRuby is a Ruby implementation that can be used to write Cocoa applications for Mac OS X. It allows Ruby code to interact with the Cocoa frameworks and Objective-C classes. The presentation introduces MacRuby and demonstrates how to use the MacRuby REPL for learning Core Data, build a MacRuby project, hook up a user interface with Ruby methods, use Ruby gems, and package applications for distribution.

- 18. MacRuby for Fun! • Let’s learn CoreData! • There sure is a lot of documentation on http://developer.apple.com about CoreData
- 19. MacRuby for Fun! • Let’s learn CoreData! • There sure is a lot of documentation on http://developer.apple.com about CoreData • Documentation is boring :-(
- 20. setup.rb
- 21. MacRuby for Fun! • Let’s learn CoreData! • There sure is a lot of documentation on http://developer.apple.com about CoreData • Documentation is boring... :-(

- 23. MacRuby for Profit! • Things you will need: • MacRuby nightly build (or 0.11 when it comes out) • Xcode 4.2 (v4.1 is definitely broken, v3- series may still work) • Gumption (and the mailing list address)
- 24. MacRuby for Profit! • Install Xcode FIRST! then MacRuby • Start Xcode, choose the MacRuby template • Build and go!
- 25. Building and Running • MacRuby template already contains targets needed to compile, build, and run • macruby_deploy does all the hard work...
- 26. Hooking Up a UI • MacRuby classes are Objective-C classes • Define outlets with attr_* methods • Any MacRuby method with a single argument named “sender” can be used as an action
- 27. Using Gems • Install with sudo macgem install <gemname> • Require Gems in rb • Use Gems for Development • Vendor Gems with macruby_deploy --gem for Distribution
- 28. Packaging and Shipping • App bundles generated by macruby_deploy are relocatable to machines without MacRuby (or even with incompatible versions of MacRuby) • Bundles can be signed for App store distribution with the codesign CLI tool • Excellent blog post at: http://astonj.com/ tech/how-to-submit-your-macruby-app-to- the-mac-app-store/
- 29. Bonus!
- 30. MacRuby... ...and you didn’t even know it!!! • CocoaPods! • https://github.com/CocoaPods/CocoaPods • Like Gems for iOS (and OS X... and MacRuby) • Uses MacRuby under the covers • Complemented by Laurent Sansonetti!
