Hello everyone, I just finished programming my first application (Mac OS X). Before submitting my application, I would like to know anything specific that I should be careful about the application features and the programming side. Also please let me know what non-obvious problems you ran into when submitting you application. My application is basically a notification system for iTunes, whenever a song is played it shows a notification and preview of the lyrics and if you click on it, it takes you a page with lyrics on it. It relies heavily on the Growl framework to deliver these notification. It also uses the Sparkle framework for updating and JSONParser library to parse json from a server. For programming, I only have 1 pair of .h/.m file for AppDelegate and about 600 lines of code. I don't see the need of any extra classes as it's just a bunch of methods most IBActions... Based on this, please give me any advice/heads up before i submit so I don't get a reject after a month and have to go through the submit process again and then wait again.... Thanks.
