I want to make a file browser app for iPhone, but I don't know where to start

I want to make a sim开发者_如何转开发ple file browser app for iPhone. (Like iFile in Cydia) It's not a just view Documents folder, it can see all directories in the iPhone/iPod Touch File System. Like a Finder on Mac/Explorer on the Windows.

Who can help me?

P.S. I'll publish to Cydia Store, not App Store.

You're going to need the iPhone SDK up and running and you're going to want to go over the NSFileManager documentation.

You can't do this if you want to publish to the app store. You are not allowed to access files outside of your own sandbox.

iOS apps operate in their own little sandboxes -- they can't see into other apps' directories. So unless you're writing an app for a jailbroken device, you're out of luck.
