I have just started trying to learn how to develop iPhone/iPad apps. I have been using the Stanford lecture videos on iTunes U, and have learned a lot so far. I did come across a problem while doing homework assignment 1B. I can't seem to figure out how to get it to work. Has anyone either watched these videos, or just knows a lot about Objective-C? If someone could post the code for the assignment so that I can figure out what I was doing wrong, that would be great! The homework assignment can be found at http://cs193p.stanford.edu As I said before, it is assignment 1B that I cannot figure out. Thanks in advance!
