COMP 446 / ELEC 446 - Week 1

  29. 2011 Class • 2011 Course filled to limit of 16 on first day • Limit raised to 17, but only through reclassification of one student • Bipolar reviews. Predominantly outstanding but … • A few students did not at all like the concept of highly leveraging the Stanford videos. • Important takeaway – most undergraduates have not had experience with SQL and HTML/JavaScript – things that are very important for real mobile applications. COMP 446 / ELEC 446 - Week 1

  30. Prerequisites • Formal prerequisites for COMP/ELEC 446 dropped • There are no other courses teaching Xcode, Objective-C, ASP.Net or other web programming • Experience from last few years clearly shows need for: • An interest in cool connected mobile devices is a must. • Homework will be satisfying when completed, but will likely take a long time. • Understanding of basic object oriented programming concepts (class, instance, inheritance, etc.) • Without OOP foundation, you will get lost in Objective-C tutorial and likely have trouble catching up COMP 446 / ELEC 446 - Week 1

  31. Object-Oriented Terms • Class • Instance • Message • Method • iVar • Inheritance • Super/Subclass • Protocol • Source: CS193p Lecture #1 - description/template for an object - manifestation of a class - sent to objects to make them act - code invoked by a Message - object-specific storage - code-sharing mechanism - inheritance relationships - non-class-specific method definition COMP 446 / ELEC 446 - Week 1
