Download a File - iPhone SDK

Question

Hello everybody,

I am sort of new to developing view-based iPhone applications, and I need to download this "txt" file off the internet and save it into the documents folder of the app. Can anyone show me simply how I can do this? The txt file is of a tiny size, so I wouldn't need any User interface objects...

Thanks,

Kevin

NSError *err = [[[NSError alloc] init] autorelease];
NSString *url = [[NSString stringWithFormat:@"http://myurl.com/mypage"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *myTxtFile = [NSString stringWithContentsOfURL:[NSURL URLWithString:url] encoding:NSUTF8StringEncoding error:&err];
if(err.code != 0) {
    //HANDLE ERROR HERE
}

Then to save it you can use:

[[NSUserDefaults standardUserDefaults] setObject:myTxtFile forKey:@"MyFile"];

And to retrieve it:

NSString *myTxtFile = [[NSUserDefaults standardUserDefaults] stringForKey:@"MyFile"];
