Day 2 I am working on a Topcoder challenge now.This challenge is solve misc client feedback enhancements and bug fixes of a iOS application. It’s too hard for me because I am java programmer before. I decide to become a iOS developer 3 months ago, because I wanna be a freelance. I think it is easy to find a freelance job as iOS developer. The challenge I am working on is very hard, not only it’s a iOS project, it is also its demand: it need allow user to setting application’s orientation. The apple is stick control application’s behavior, so this demand it nearly impossible to fulfill. It’s a depressing day.
