The most correct way would be to use NSURLComponents to append the fragment:

NSURL* fileURL = [NSURL fileURLWithPath:somePathString]; // or, even better, an API that gives file URLs directly, skipping the path string
NSURLComponents* components = [NSURLComponents componentsWithURL:fileURL resolvingAgainstBaseURL:YES];
components.fragment = @"anchorname";
NSURL* urlWithFragment = components.URL;


If you can't use NSURLComponents because you're targeting releases of OS X before 10.9, you should just use string operations:

NSURL* fileURL = // … as above …
NSString* urlString = fileURL.absoluteString;
urlString = [urlString stringByAppending:@"#anchorname"];
NSURL* urlWithFragment = [NSURL URLWithString:urlString];

Regards,
Ken
