Why Are We Here?
To build iPhone & iPod touch applications using Cocoa Touch
Tuesday, September 23, 2008
7
Why Are We Here? • 193P is not just about the iPhone, Cocoa Touch or ObjC • It’s about Software Engineering, as well as object oriented
architecture and design • Exposure to problems and solutions that you might not see in other classes
Tuesday, September 23, 2008

Stanford iPhone Pilot • Applications by Stanford students for Stanford students • Project information: ■
http://studentapps.stanford.edu/iapps.html
• Details on the current applications ■
http://stanford.terriblyclever.com
• Contact Joe and Kayvon for more details about the program • Keep in mind for final projects
Tuesday, September 23, 2008
9
Cocoa Touch & iPhone SDK • The Good Based on Cocoa which is mature, well thought out with highly consistent APIs ■ Provides a very rich starting point for exploring app design ■ Shows “real-world” implementations of OO design patterns ■ Designs learned on iPhone translate directly to Mac OS X ■
• The Bad 1.0 version of SDK, bound to be some rough edges ■ Exploring new territory with classroom device development ■
• The Ugly ■

Buzz about the class • Bloggers asked, “How can they teach the class with Apple’s NDA?”
“Basically, it's like Fight Club. Once you enroll in the iPhone developer program, you're not allowed to talk about the developer program, the SDK, or pretty much anything until Apple says it's OK.”
Tuesday, September 23, 2008
11
iPhone Developer University Program • Some materials for the class still covered by confidentiality clause
Existing iPhone developer program restricts who developers can talk to about SDK details ■ University program allows schools to create teams of students who can talk to each other, exchange applications, etc. ■
• Students will be “invited” to join our CS193P team ■
Accepting invitation includes agreeing to honor these terms
• Once accepted, you can download the SDK…and we can talk

THIS CLASS HAS BEEN RATED
R
STUDENTS STRONGLY CAUTIONED SOME MATERIAL MAY BE INAPPROPRIATE FOR STUDENTS WHO HAVE NOT ACCEPTED THE UNIVERSITY AGREEMENT
For brief exposure to confidential API and details about iPhone OS. Do not discuss with anyone not enrolled in this class.

Why Objective-C? • Exposure to other languages is always good • ObjC is a language focused on simplicity and the elegance of OO design
Based on ANSI C ■ Brings many object oriented principles, but with a minimal amount of syntax ■
• A data point to compare with designs of C, C++ and Java
