iOS NSDataDetectors vs NSRegularExpressions - Better approach?

Question

I have a scenario that em implementing that I need to extract URLs from given NSStrings, so i came to find 2 ways to do so (by the Help of SO :))…

Such that I have a NSString like this

NSString *someString = @"This is a sample of a http:\/\/www.abc.com\/efg.php?EFAei687e3EsA sentence with a URL within it.";

and then i can use both these ways to get the URL out of the string...

1st way

NSRegularExpression *expression = [NSRegularExpression regularExpressionWithPattern:@"(?i)\\b((?:[a-z][\\w-]+:(?:/{1,3}|[a-z0-9%])|www\\d{0,3}[.]|[a-z0-9.\\-]+[.][a-z]{2,4}/)(?:[^\\s()<>]+|\\(([^\\s()<>]+|(\\([^\\s()<>]+\\)))*\\))+(?:\\(([^\\s()<>]+|(\\([^\\s()<>]+\\)))*\\)|[^\\s`!()\\[\\]{};:'\".,<>?«»“”‘’]))" options:NSRegularExpressionCaseInsensitive error:NULL];
NSString *match = [someString substringWithRange:[expression rangeOfFirstMatchInString:someString options:NSMatchingCompleted range:NSMakeRange(0, [someString length])]];
NSLog(@"%@", match);

2nd way

NSDataDetector *linkDetector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypeLink error:nil];
NSArray *matches = [linkDetector matchesInString:someString options:0 range:NSMakeRange(0, [someString length])];
for (NSTextCheckingResult *match in matches) {
  if ([match resultType] == NSTextCheckingTypeLink) {
    NSURL *url = [match URL];
    NSLog(@"found URL: %@", url);
  }
}

My question is which one is better and faster as I have around 400 to 500 NSStrings to parse at an instance.

Thank you in advance.
