Downloading from FTP server iOS 7

Question

I have tried this:

NSURL *url = [NSURL URLWithString:ftpURL];    
NSData *data = [NSData dataWithContentsOfURL:url];            
if (data){
   [data writeToFile:dataPath atomically:(YES)];
}

But it doesn't seem to work... I have initialised dataPath, and ftpURL elsewhere..I know they aren't null. And data just returns null for some odd reason.

Does the above method support FTP download?

I have also searched on Google and StackOverflow regarding this and I couldn't find a solution that would help me. I saw SimpleFTPSample and I thought the above method was easier.

Have you tried using dataWithContentsOfURL:options:error: and looking at the NSError return? — mjswan, Oct 07 '13 at 21:51
@user959631 The [first answer](http://stackoverflow.com/a/14484610/24073) shows how to download via FTP. — neilco, Oct 07 '13 at 21:58
Turns out that my `url` is returning null too. I checked `ftpUrl` and that definitely isn't null. Weird. — user959631, Oct 07 '13 at 22:07
@neilco Wow, I completely missed that. God I am so tired. Sorry for that =] — user959631, Oct 07 '13 at 22:08
Ok, so how would I write the `readStream` to file? `CFStringRef url = CFSTR("ftp://ftp.somedomain.com/file.txt"); CFURLRef requestURL = CFURLCreateWithString(kCFAllocatorDefault, url, NULL); CFReadStreamRef readStream = CFReadStreamCreateWithFTPURL(kCFAllocatorDefault, requestURL);` — user959631, Oct 07 '13 at 22:18

Ok, I found out my problem, NSURL was returning null because I needed to stringByAddingPercentEscapesUsingEncoding my ftpURL string.

Thanks guys for the help anyway =]
