6. RubyMotion
7. RubyMotion - Wat? /ˈro ͞ ob ē -m ō SHən/ noun trademark 1. A proprietary toolchain, created by HipByte SPRL, for developing native iOS and OS X applications on Apple devices and computers by statically compiling the Ruby programming language. OR Apps the Ruby Way
8. Quick Example Objective-C button tap [button addTarget:self action:@selector(buttonTapped:) forControlEvents: UIControlEventTouchUpInside]; // Elsewhere - (void)buttonTapped:(id)sender { self.view.backgroundColor = [UIColor redColor]; } RubyMotion button tap button.addTarget(self, action:'button_tapped', forControlEvents:UIControlEventTouchUpInside) # Elsewhere def button_tapped self.view.backgroundColor = UIColor.redColor end
9. Better Example Objective-C button tap [button addTarget:self action:@selector(buttonTapped:) forControlEvents: UIControlEventTouchUpInside]; // Elsewhere - (void)buttonTapped:(id)sender { self.view.backgroundColor = [UIColor redColor]; } RubyMotion button tap (with sugarcube gem) button.on(:touch) do self.view.backgroundColor = :red.uicolor end

11. What's So Great About RubyMotion? In my opinion Gems and Community Editor Independence Testing! Readability Natively Compiled The REPL
12. RubyMotion Analogy RubyMotion is to Objective-C As Coffeescript is to Javascript ... plus gems are kind of like jQuery plugins ... plus MacBacon has spec tests like Jasmine would ... plus the REPL lets you live-modify like developer tools ... plus it compiles and obfuscates your final codebase ... OK, this analogy got out of control
13. Let's Look At Code! Classic - Hello World Full App - Ruby Trivia Games!
14. Hello World $ motion create test Tests will fail class AppDelegate def application(application, didFinishLaunchingWithOptions:launchOptions) @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds) @window.rootViewController = HelloWorldController.new @window.makeKeyAndVisible true end end class HelloWorldController < UIViewController def viewDidLoad p "Hai" end end Now tests pass!
15. Hello World - REPL main_view = UIApplication.sharedApplication.windows[0].rootViewController.view main_view.backgroundColor = UIColor.blueColor OR , just command click the view! # REPL input self.backgroundColor = UIColor.whiteColor @label = UILabel.new @label.text = "Hello World" @label.sizeToFit self.addSubview(@label) # get down from there! @label.center = [100, 100] OR , use sugarcube-repl's tree command.
