Objective-C Vitamins

This is a talk that I gave at Tech Talks TO about the three things that the Objective-C community needs to embrace to grow into a mature, stable platform: Accessibility, Unit Testing, and Open Source.

2. Accessibility
3. Matters Accessibility
4. Ontario Citizens 1 in 7
5. Ontario Citizens Broader 1 in 7 Appeal Market
6. Legislation Ontario Citizens Broader AODA 1 in 7 Appeal Market
7. Legislation Ontario Citizens Broader Low Cost in iOS AODA Relatively 1 in 7 Appeal Market
8. iOS is and visual aural
9. You wouldn’t ship a bad visual interface Why would you ship a bad aural one?
10. Accessibility is HARD
11. WHY?
12. TURN VoiceOver ON (seriously)
13. Accessibility is EASY
14. UIAccessibility
15. Part of UIKit Built in UIAccessibility
16. Part of UIKit Built in UIAccessibility Conformed to by UIView Built in
17. Part of UIKit Built in UIAccessibility Conformed to by UIView Built in You can roll your own Built in
18. UIAccessibilityTraits Causes Page Turn Starts Media Session None Button Link Search Field Image Plays Sound Keyboard Key Static Text Summary Element Not Enabled Updates Frequently Adjustable Allow Direct Interaction Header Selected
19. invisible THE BUTTON
20. Using as button labels
21. drawRect: UITableViewCell

24. Testing Unit
25. WHAT IS UNIT TESTING?
26. WHY UNIT TEST?
27. MODEL CONTROLLER VIEW KVO OWNS OWNS USER INTERACTION
28. MODEL CONTROLLER VIEW KVO OWNS OWNS USER INTERACTION EXTENSION EXTENSION
29. “Common things are easy and uncommon things are possible.”
30. Uncommon “Common things are easy and uncommon things are possible.” Unit Testing is
31. Uh oh.
32. Yes! In Objective-C?
34. - (void)testExample { STFail(@"Unit tests are not implemented yet in My Sweet New AppTests"); }
35. And that’s it.
36. OCMock Introducing
37. Objects Mock
38. NSURLRequest *dummyURLRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http:// example.com"]]; PXRequest *requestUnderTest = [[PXRequest alloc] initWithURLRequest:dummyURLRequest completion:nil]; id mockConnection = [OCMockObject niceMockForClass:[NSURLConnection class]]; [[mockConnection expect] start]; id partialRequestMock = (PXRequest *)[OCMockObject partialMockForObject:requestUnderTest]; [[[partialRequestMock stub] andReturn:mockConnection] urlConnectionForURLRequest:OCMOCK_ANY]; [partialRequestMock start]; [mockConnection verify]; A Simple Test A lot of Code
39. Why?
40. Because OCMock is OLD and BUSTED
41. New Hotness Kiwi
42. Integrates Xcode with
44. describe(@"ClassName", ^{ context(@"a state the component is in", ^{ __block id variable = nil; it(@"should do something", ^{ [[variable should] meetSomeExpectation]; }); specify(^{ [variable shouldNotBeNil] }); }); });
45. describe(@"ClassName", ^{ context(@"a state the component is in", ^{ __block id variable = nil; beforeAll(^{ // Occurs once }); afterAll(^{ // Occurs once }); beforeEach(^{ // Occurs before each enclosed "it" variable = [MyClass instance]; }); afterEach(^{ // Occurs after each enclosed "it" }); }); });

55. DEVELOPERS STUBBORN are
56. DEVELOPERS DON’T KNOW
57. THE TOOLS SUCK
