I have a website, let's say it's "http://www.jwilkthings.com/stuff"
I have a bunch of .txt files stored on this website, i.e. "http://www.jwilkthings.com/stuff/text1.txt"
What I'm wanting to do is find a way in iOS to download all of those text files without knowing what the document name is. I can already retrieve them manually as long as I have a file name, but I would rather just get all of them at once and put them in the documents directory if possible. I currently use FileZilla to upload all of the text files, so I can use FTP if needed.
The correct way to solve this problem is to not use FTP (riddled with performance and security issues), and to configure your web server to expose a table of contents directory listing that your client can parse.
But that's not an answer to your question. If you really want your iOS app to speak FTP, take a look at the SimpleFTP sample project from Apple.
It's old, but I just got it to build on iOS 5. The ListController.m file has the code you're looking for.
