Process Learn iOS and Objective-C through a series of small applications Leverage an excellent set of online videos to augment a mixture of
lectures and seminars. Develop an awareness of the changing factors influencing the
mobile industry. Apply this knowledge for a final project taking most of the second
half of the semester

New competition from Palm Blackberry and Nokia still holding on to large customer base Windows Mobile continues to lose ground – but many have been hurt

Fast rise by Android platform and modest % rise by iPhone Decrease in market share from Symbian, RIM and Windows Mobile, Palm
Android 2.x and various ‘Droid’ devices provide first real competition to
the iPhone.
About 200,000 Android devices being sold every day.

2009 COMP 446 – iPhone Transition Mobile devices proliferating exponentially General consensus was that smartphones are for
upper end market only
But that is not the view of a technologist
Strong desire to teach iPhone app class

Taught by Apple people and at an elite university level Could handle the heavy lifting language portion of the class

Results from 2010 Class
2010 Course filled to limit of 10 on first day Limit raised to 16 on second day, filled in hours Acquired larger room
More topics to cover in 2010
Registration grew to 22 before first class. Accepted 5 walk-ins for a total of 27 Some things had to be de-emphasized to make room
Evaluations were good, but markedly worse than 2009.
Far too many people to effectively support Some students signed up for course because of cancellation of another specialization course.

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.

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.)
SEC - 8/22/12
Without OOP foundation, you will get lost in Objective-C tutorial and likely have trouble catching up
COMP 446 / ELEC 446 - Week 1

Object-Oriented Terms Class
- description/template for an object Instance - manifestation of a class Message - sent to objects to make them act Method - code invoked by a Message iVar - object-specific storage Inheritance - code-sharing mechanism Super/Subclass - inheritance relationships Protocol - non-class-specific method definition

Discussion of current project, future projects and / or next step in current project Homework 6 initial projects; most lasting one week. Homework and mandatory videos
Videos must be watched before class Assignments due Friday at 6:00am (think of it as Thursday at 30:00). You will have all the resources needed to start early and get ahead.
Final project

iPhone Development Videos Leveraging iTunes-U, Stanford University CS193P course. Significant homework will be in the form of watching external 1hr videos and their coordinated exercises.
Experiment when it started three years ago which proved quite effective.
It will be nearly impossible to do the assignments without watching the videos.
Logistics:
Expect 2 full and possibly one optional video per week as well as one application through the first half of the semester You will eventually watch all of the CS193P lectures, and do problems up to and including assignment 6 (although assignment 6 may have a required and an optional component)

OS X & Xcode version OS X Mountain Lion has desirable but not required features Developing iOS apps does not require much disk space or GHz Large screen not needed but helpful University Macs running Lion Xcode 4.4 (or 4.4.1) is desired, not required Definite improvement over in integration and debugging Not materially different than version on videos. iTunes videos use Xcode 4.2.

Optional Sessions and Support Sunday or Monday office hours with TA. Schedule to be
determined between class and Richard Latimer. 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.

Syllabus Overview First Half of Semester Pedagogical approach to iPhone programming through a series of lectures and assignments that build on each other Mandatory iTunes-U lectures covering basic iOS functionality Second Half of Semester Dominated by one large project.
Students choose projects, platforms
Typically solo final projects. There will be significant guidelines and possibly suggested projects
Optional videos covering subjects of general interest to all, but specific interest only to those working the technology

class format and mobile technology changes quickly

Is COMP 446 for You? Do you agree with benefits of the COMP 446 format? Lectures, projects and most importantly leveraging the iTunes CS193P videos Are you prepare to spend at least 10 hours a week on the initial
projects?
Are you the sort who really enjoys getting a program to work? Do you have the time in your schedule?
Some do not understand or like the format If this is you, drop this course and learn iOS from books or iTunes-U Most COMP 446 students strongly say yes If this is you, you will have a great time in COMP 446 SEC - 8/22/12
