title: Document Directory in iPod Touch and iPhone
body: <p>I'm designing an application that reads data to the iPod touch/iPhone that is sent to it via multicast sockets with UDP and I need to store it as a file in a document directory. Does that exist on on the iPhone or iPod Touch? I know there is NSFileHandle and NSFileManager, which is what I plan on using, to take care of reading and writing to the file, but I'm not sure where the "My Documents" section of the iPod touch is if you know what I'm saying. I am not familiar with the iPod/iPhone file directory that well yet, so any help is appreciated! Is there some kind of "general" directory that all developers use to store their files in if they have any involved in their application?</p>
