29. RUBYMOTION introduction Monday, September 2, 13
30. RubyMotion RubyMotion apps are created and later maintained from the terminal command-line. A RubyMotion project is based on the Rake tool and can be configured by editing its Rakefile. Monday, September 2, 13
31. RubyMotion Requirements RubyMotion requires a Mac Install the iOS and OS X SDK Monday, September 2, 13
32. $199 RubyMotion Requirements and... Monday, September 2, 13
33. Rubymotion Hello World Monday, September 2, 13
34. RubyMotion Hello World class AppDelegate def application(application, didFinishLaunchingWithOptions:launchO alert = UIAlertView.new alert.message = "Hello World!" alert.show true end end $ motion create hello_world Monday, September 2, 13
35. RubyMotion Hello World alert = UIAlertView.new alert.message = "Hello World!" alert.show $ motion create hello_world Monday, September 2, 13
36. RubyMotion Hello World Monday, September 2, 13
37. RubyMotion Hello World Use Your ruby development tools Monday, September 2, 13
38. RubyMotion Object Model Ruby Model implemented from Objective-C runtime In RubyMotion, Ruby classes, methods and objects are Objective-C classes Objective-C classes, methods and objects are available in Ruby as if they were native. Monday, September 2, 13
39. RubyMotion Object Model Objective-C and RubyMotion share the same object model infrastructure. Objective-C and RubyMotion APIs can be interchangeable at no additional performance expense. Monday, September 2, 13
40. RubyMotion Object Model Monday, September 2, 13
41. RubyMotion Objective-C Messages [string drawAtPoint:point withFont:font]; variable variable variable Monday, September 2, 13
42. RubyMotion Objective-C Messages [string drawAtPoint:point withFont:font]; Message keyword Message keyword Monday, September 2, 13
43. RubyMotion Send messages from RubyMotion to Obj-C string.drawAtPoint(point, withFont:font) Monday, September 2, 13
44. RubyMotion Dispatch Messages manually string.send(:'drawAtPoint:withFont:', point, font) Monday, September 2, 13
45. RubyMotion view.hidden = true unless view.hidden? Monday, September 2, 13
46. RubyMotion Monday, September 2, 13
47. RubyMotion Interfacing with C Basic Types Basic C types cannot be created from Ruby directly, but are automatically converted from and to equivalent Ruby types. Monday, September 2, 13
48. RubyMotion Structs pt = CGPoint.new pt.x = 100 pt.y = 200 'Hello'.drawAtPoint(pt, withFont: font) #It is possible to pass the field values directly to the constructor. pt = CGPoint.new(100, 200) 'Hello'.drawAtPoint(pt, withFont: font) #RubyMotion will also accept arrays as a convenience. #They must contain the same number and type of objects expected in the structure. 'Hello'.drawAtPoint([100, 200], withFont: font) C structures are mapped to classes in RubyMotion. Monday, September 2, 13
49. RubyMotion Pointers rect_ptr = Pointer.new(CGRect.type) rect_ptr = Pointer.new(:int) C type pointer Structure pointers Monday, September 2, 13
