Assignment Last week, you created the first version of Presence, an iPhone application for viewing online status updates. This week, we’ll improve the application in two major ways. First, we’ll make the switch from hardcoded views to table views, so that our application can display large, dynamic data sets. Second, we’re going to read local data from property lists and fetch remote data using web services, displaying actual content in our application. | CS193P Spring 2009 Presence 2 Doll Cannistraro Presence - Part 2 Due Date This assignment is due by 11 59 PM May 5. Assignment Last week you created the first version of Presence an iPhone application for viewing online status updates. This week we ll improve the application in two major ways.
