  8. Software Course Website: www.comp446.com assignment submission website linked through www.comp446.com iPhone Developer Program iPhone Documentation available at http://developer.apple.com Students will be enrolled in Rice’s iPhone University Developer’s Program You should have already responded to invitations Xcode available free on Macs Remember User: xcode, Password: xcode COMP 446 / ELEC 446 - Week 1
  9. Assignment Files Unless otherwise instructed, submit assignment files as a zip file of Xcode project directory. Ensure that all resources are part of the project directory so they are included in zip. Clean project before archiving. Greatly reduces size. Screen shots or PDF documents preferred for some assignments (when indicated). OK to make multiple submissions when both file types needed – but not of individual Xcode project files. COMP 446 / ELEC 446 - Week 2
  10. Optional Sessions and Support Monday office hours with TA Richard Latimer. 4:00pm Mudd Additional session Thursday, 9pm on 8/30 and 9/6. Ability to email questions to me at any time. Can email Richard Latimer as well. Level of support will vary over semester High level of support at the beginning. Support decreasing each project as over time as knowing where to look or how to debug is a very important skill for you to learn. Richard instructed to respond conceptually – not just provide solutions. COMP 446 / ELEC 446 - Week 1

  16. Discussion

  17. Who is Paul Hegarty Better question: Why is an Objective-C string called NSString How are these two questions related and why is it relevant to the high quality of these videos. COMP 446 / ELEC 446 - Week 2
  18. Object-Oriented Terms Class (description/template for an object) Instance (manifestation of a class) Instance Variable (object-specific storage) Message (sent to objects to make them act) Method (code invoked by a Message) Inheritance (code-sharing mechanism) Super/Subclass (Inheritance relationships) Protocol (.h without .m with other objects announcing suport) Source: CS193p Lecture #1 COMP 446 / ELEC 446 - Week 2
  19. Xcode 4 - You’ve learned how to ... Create a new project with a single MVC Show various files in your project (via Navigator or clicking on bars at the top of files) Show and hide the Navigator, Assistant Editor, Console, Object Library, Inspector Drag objects into your view and edit their size, position and object-specific display attributes Ctrl-drag to connect objects in your View to the code in your Controller (outlets and actions) Show connections to outlet @propertys and action methods (by mouse-over or right click) Get quick help (option click) or full documentation (option double-click) for symbols in your code Run your application in the simulator Click on warning (yellow) and error (red) indicators to see problems in your code Create a new class (like CalculatorBrain) using the File menu’s New File ... item Create browser-like tabs to organize your viewing of your project Source: CS193P 2011 Lecture 3 COMP 446 / ELEC 446 - Week 1
  20. Objective C - You’ve learned how to ... Define a class’s public @interface and private @implementation in a .h and .m file respectively Add a private @interface to .m file Create a @property, both for a primitive type (like BOOL) and a pointer (like NSMutableArray *) Use nonatomicin @property declarations Use strong or weak in @property declarations of pointers to objects Use @synthesize to create a @property’s setter and getter and backing instance variable Use “= _propertyname” to choose the name @synthesize uses for its backing instance variable For pointers to an object, use either the special type id or a static type (e.g. UIButton *) Declare and define an Objective C method (e.g. pushOperand: or popOperand). Declare local variables both of type “pointer to an object” (id or static type) and primitive type Source: CS193P 2011 Lecture 3 COMP 446 / ELEC 446 - Week 1
  21. Objective C - You’ve learned how to ... Invoke an Objective C method (using square bracket [] notation) Invoke a setter or getter using dot notation (e.g. self.operandStack or self.display.text) Lazily instantiate an object by implementing your own @property getter (operandStack & brain) Wrap a primitive type (like double) in an object (using NSNumber) Log formatted strings to the console using NSLog() Use a “constant” NSStringin your code using @“” syntax (e.g. @“+”) Add and remove an object from an NSMutableArray(the last object anyway􀀁). Use alloc and init to create space in the heap for an object (well, you’ve barely learned this). #import the .h file of one class into another’s (CalculatorBrain.h into your Controller) Create a string by asking a string to append another string onto it Create a string with a printf-like format (e.g., [NSStringstringWithFormat:@“%g”, result]) Perhaps you’ve learned even more if you’ve done Assignment #1! Source: CS193P 2011 Lecture 3 COMP 446 / ELEC 446 - Week 1
  22. Syntax Conventions Class object capitalized NSObject, NSArray, etc. Method names are lower case stringByAppendingString Instances of classes are in lower case self, myBrain Long names have capitals bounding words stringByAppendingString Brain is not the same as brain COMP 446 / ELEC 446 - Week 1
  23. (almost) Everything is an Object Classes, instances, types, colors Major exceptions are C-structs as are numbers (but not NSNumbers) You can send messages to classes [[MyClassalloc] init]; [NSStringstringByAppendingString] (ClassName) does not change an object’s class, but tells Xcode that it can assume object is of class ClassName. COMP 446 / ELEC 446 - Week 1
  24. To * or not to * An object instance variable is only a pointer Initially set to nil (which is 0) You can safely send messages to nil NSString foo = @”This is not correct syntax”; NSString *foo =@”This is correct syntax”; id foo = @”id types do not use a *”; We will latter see **foo implying a pointer to a pointer. COMP 446 / ELEC 446 - Week 1
  25. Assignment #1 Questions COMP 446 / ELEC 446 - Week 2
  26. The Legacy of Steve Jobs COMP 446 / ELEC 446 - Week 2
  27. Waves of Technology Every 10 years or so, something big changes Core leaders of this technology often young Luck or Skill Many people have one great idea, some two Few have one great idea after another Often requires excellence in multiple areas Risk and Failure COMP 446 / ELEC 446 - Week 2
  28. First or Best Being first gives you a head start, but also paints a target for those who follow behind. Steve Jobs often took an existing area and through a set of bold moves changed the paradigm giving people what they really wanted – or would discover that they needed. COMP 446 / ELEC 446 - Week 2
  29. Importance of Owning Solution Allows differentiation and future shaping in cost competitive environment. Eases introduction of new technology Enables bold moves Great competitive barrier to entry But can also cost significant business if not at or near best of breed in an important area. COMP 446 / ELEC 446 - Week 2
  30. Master of Presentations 1983 Apple Keynote-The "1984" Ad Introduction 1984 Superbowl Commercial The Lost 1984 Video: young Steve Jobs introduces the Macintosh The charisma of Steve Jobs (video roundup) COMP 446 / ELEC 446 - Week 2
  31. Hyperbole Apple iPad Keynote in 2 minutes! [HD] Back To The Mac in 104 seconds Incredible amazing awesome Apple The Original Apple Keynote Cutdown. No cuts are repeated.Done with iMovie, which is really awesome... COMP 446 / ELEC 446 - Week 2
