Are you sure the user is entering a valid URL and not a file path? If it's a path, then you need to use -initFileURLWithPath: and not -initWithString:, and the path shouldn't be percent-escape encoded.
Have you tried passing a pointer to an NSError pointer into the -initWithURL:error: message? The error you get back, if any, should tell you why it's not working.
