This is a very simple task but I haven't seen it documented anywhere.
NSURL *url = [NSURL URLWithString:@"http://tinyurl.com/api-create.php?url=www.yoururl.com];
NSString *strUrl = [NSString stringWithContentsOfURL:url encoding:NSASCIIStringEncoding error:nil];
Now use your strUrl pointer wherever you want the shortened URL.
