Apple Speak Strong visions Loyal followings Internally consistent Unique ways to describe standard concepts SEC - Beatler Day COMP 446 / ELEC Week 38

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. SEC - Beatler Day COMP 446 / ELEC Week 39

Delegation Examples applicationDidFinishLoading applicationWillTerminate // Required method - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section; // Optional method, defaults to 1 if not implemented - (NSInteger)numberOfSectionsInTableView:(UITableView *)table; SEC - Beatler Day COMP 446 / ELEC Week 310

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 SEC - Beatler Day COMP 446 / ELEC Week 311

Objective-C an NSString object or selector. Also many //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 SEC - Beatler Day COMP 446 / ELEC Week 312

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. SEC - Beatler Day COMP 446 / ELEC Week 313

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 the 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.

Final Project To be determined by end of 9 th week Topic chosen shortly after mid semester break (10/21/09) Spec finished by 11/04/09 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 SEC - Beatler Day COMP 446 / ELEC Week 322
