Don't do this using threads. Cocoa's networking APIs are asynchronous, so you can start a download using NSURLConnection and it will run in the background and notify your delegate when it's complete.

You almost never need to start threads in Cocoa programming. This can be hard to adjust to if you come from other frameworks, esp. Java.
