Error in FlickrFetcher.m

Class -

In the FlickrFetcher class that we originally included with the Paparazzi 2 files, we had an error in:

- (NSArray *)fetchManagedObjectsForEntity:(NSString*)entityName withPredicate:(NSPredicate*)predicate

The method takes "entityName", but we were then hardcoding a value of "FlickrUser" instead of using the variable being passed in. If you've already downloaded these files, line 77 should read:

NSEntityDescription *entity = [NSEntityDescription entityForName:entityName inManagedObjectContext:context];

instead of

NSEntityDescription *entity = [NSEntityDescription entityForName:@"FlickrUser" inManagedObjectContext:context];

If you haven't yet downloaded the files, they should now be correct on the website.

Also, some of you have noticed that your project may not build without importing a new Framework for CoreData functionality. In Xcode if you open the Targets group on the left and double click on the target you have in there that will open the Target Info pane. In the General tab there's a Linked Libraries list at the bottom. Is CoreData.framework in there? If not, use the plus button below the list to add it and then you should be good to go.

Good luck,

Alan

Special Friday OH on SDK Setup

This Friday (tomorrow) the TAs will hold a special session of office hours in Gates 360, from 3:30-5:00 PM.

The intent of this office hours is to both help students with questions about the course/assignments, but also to help any students that are having issues installing the iPhone SDK on their machines. If you are having issues getting set up, please have already downloaded the SDK before arriving (you can get it at http://developer.apple.com/iphone/).

Lecture #2 - Objective-C and Foundation Framework

We're making good progress on the enrollment surveys and hope to have the process completed tomorrow afternoon. An email will go out to everyone that submitted a survey letting you know whether you are in or not.

At the same time we should have the developer team straightened out, details will follow. If you want to get a jump on the assignment before we have the team set up, you can sign up for a free iPhone developer account at http://developer.apple.com/iPhone which will give you access to the iPhone SDK (simulator only).

David's office hours are Mondays 4-6 PM in Gates 360.

Today we went over the basics of Objective-C and introduced a variety of Foundation framework classes.

Lecture #1 - Welcome to CS193P

We kicked off a new quarter of 193P to a jam packed room (including Rein and Kalev, our youngest students ever who are getting a jump following in their mom's footsteps!). We're looking forward to a great quarter and can't wait to see the amazing apps that all the students come up with.

The lecture slides and handouts will be posted here, usually shortly after lecture but we'll try to do them before whenever possible. Have a look at the class overview handout which has answers to a lot of the frequently asked questions. If you have questions about the class that aren't answered in the overview, please don't hesitate to to drop us a line at cs193p@cs.stanford.edu.

If you are looking to enroll in the class, you MUST fill out a survey. You can find the survey here: http://tinyurl.com/cs193p-2010. You need to fill out this survey by Weds Jan. 6, by noon. We will determine enrollment and email students who are admitted hopefully by the end of the week. We will have a waiting list of students in case spaces open up in the first couple weeks.

The first week's assignment is also posted. It consists of 2 parts: the first is very simple and intended to get you situated with the development tools and environment, the second is an introduction to Objective-C by way of a command line utility.

Keep an eye on this page for any announcements related to the class, it should be your first stop for any questions. We will also post links to the iTunes U videos when they become available.

Classes start January 5!
