COMP 446 / ELEC 446 - Week 3

  14. Apple Speak • Strong visions • Loyal followings • Internally consistent • Unique ways to describe standard concepts • Remember: It is a religion! • Two interesting short videos: • http://www.youtube.com/watch?v=0FW-lrMXLBE • http://www.youtube.com/watch?v=1ZS8HqOGTbA COMP 446 / ELEC 446 - Week 3

  15. Delegation • Lecture 4 has long, confusing discussion on Delegates • Scott Cutler method to describe delegates • Frameworks contain many classes • Implementation of some classes either require or optionally allow customization / user coding. • Delegates are a set of methods primarily related to a system class • Required methods need to be written to complete class • Optional methods have default actions that can be overridden by the programmer. COMP 446 / ELEC 446 - Week 3

  16. Delegation Examples • applicationDidFinishLoading • applicationWillTerminate • // Some are required methods- (NSInteger)tableView:(UITableView *)tableViewnumberOfRowsInSection:(NSInteger)section; • // Some are optional methods, • this one defaults to 1 if not implemented - (NSInteger)numberOfSectionsInTableView:(UITableView *)table; COMP 446 / ELEC 446 - Week 3

  17. Objective-C Terminology ; Every statement ends with a semicolon + Refers to a method on a Class - Refers to a method on an instance of a Class { } Groups Objective-C statements [ ] [object method OptionalArgs] () Casts an object as a certain Class, Also parameters for C functions * Pointer to an object e.g. *stringVar (** = pointer to *) : Specifies an argument. Also used in definitions COMP 446 / ELEC 446 - Week 3

  18. Objective-C Terminology @ Prefaces an NSString object or selector. Also many compiler directives (@Interface, @Implementation, @End // Comments . Shortcut to get or set a property # Compiler Directives like #import ! Not (as in !=) += Standard C style arithmetic (Also ++, -=, etc) % typed placeholder in formatted strings == Identity compare COMP 446 / ELEC 446 - Week 3

  19. Objective-C Naming • Case Matters!!! • LastName is not the same as lastName • Tradition has identifiers and methods made of concatenated names with the first name in lower case and the remaining names with an uppercase first letter. • Examples: lastName, openFile, initWithObjects • Compiler will make some things easier when conventions are followed. COMP 446 / ELEC 446 - Week 3

  20. iVars and Properties • Two concepts; often related and often confused • iVars are the instance variables. Space is allocated from the heap when instanced allocated. They are associated with that instance of the object (although they can be objects in their own right) • Properties are readable and/or writeable attributes of a class instance. They can be set to just set or get an iVar. They also can report or change aspects of the instance (e.g. canVote) • Often best to give properties different names from iVars due to visibility scope issues. COMP 446 / ELEC 446 - Week 3

  21. Last Week’s Assignment COMP 446 / ELEC 446 - Week 3

  27. Section 4 – Introspection (inspect) for (NSObject *arrayObjectinrandomArray){ NSLog(@"Class name: %@",[[arrayObject class] description]); NSLog(@"Is Member of NSString: %@",[arrayObjectisMemberOfClass:[NSString class]] ? @"YES" : @"NO"); NSLog(@"Is Kind of NSString: %@",[arrayObjectisKindOfClass:[NSString class]] ? @"YES" : @"NO"); if ([arrayObjectrespondsToSelector:@selector(lowercaseString)]){ NSLog(@"Responds to lowercaseString: Yes"); NSLog(@"lowercaseString is : %@",[[arrayObject description] lowercaseString ]); }else{ NSLog(@"Responds to lowercaseString: No"); } NSLog(@"===================================="); } } //PrintIntrospectionInfo COMP 446 / ELEC 446 - Week 3

  28. Final Project • To be determined by end of 9th week • Topic chosen shortly after mid semester break (10/19/10) • Spec finished by 10/26/10 • This is VERY important. If we do not have a great project definition, the most interesting part of the course will suffer. With a great project, this will be an exciting course. • Can be done individually or in pairs • Great if your project could have life after the class finishes COMP 446 / ELEC 446 - Week 3

  29. Week 4 • Assignments • View CS193P Lectures 3 and 4, 4a (Xcode, Finding Help, Debugging (1/15) • Download and complete CS193P Assignments 2a and 2b • 2a – Add a Polygon model to your What-A-Tool project • 2b – First part of your HelloPolly iPhone Application • Use 2b Walkthrough to complete assignment 2b • Contact me or Richard Latimerif you need our assistance. • Complete assignments by end of day Tuesday (9/14/2010) • Note: On LogMeIn, Control Drag does not work as if you were local • Introduction to ASP.Net and html • Future • Feel free to get ahead of plan with videos and assignments • Projects will get harder with each assignment, but you will be spending less time on the mechanics of using Xcode, etc. • We will follow CS193P assignments up to and including Paparazzi 3 • Start thinking about big project COMP 446 / ELEC 446 - Week 3
