Lecture #13 – Debug/Search/Notification/Presence 4 Demo

Filed under: cs 193p — gregorykaiser @ 3:11 pm

I watched lecture 13 last night and thought it was a bit scattered. Make sure and watch the beginning (at 2:20) where debugging programs with obj-c exceptions is covered. The two main hints were to set a breakpoint at “objc_exception_throw” and to look at the “Console” output for the best hints at where your program died.

At 57:00 Presence #4 is demoed. The additions from Presence #3 are using the address book, adding a “tab” navigation bar and searching for data.

The actual topics of the lecture are Searching for Data with UISearchBar (9:30), using “Notification” in your code to find out about events (19:50) and “Key Value Coding/Observing” (33:30). The “Notification” part was most interesting to me. Presence #4 is the last assignment before the final project. The final project is due Sunday 6/7.

Today our Google group has grown to 545 members.
