Validate URLs which contain emojis in Objective-C

Question

I'm validating URLs with the following method:

+ (BOOL)confirmValidUrl:(NSString *)url {

    BOOL isValidURL = NO;
    NSString *urlRegEx = @"(?:www\\.)?[\\w\\d\\-_]+\\.\\w{2,3}(\\.\\w{2})?(/(?<=/)(?:[\\w\\d\\-./_]+)?)?";
    NSPredicate *urlPredic = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", urlRegEx];
    isValidURL = [urlPredic evaluateWithObject:url];

    return isValidURL;
}

Now I need to mark as valid URLs the ones that have emojis like http://.la but I haven't found anything related to this, does someone know how I should modify my method to do what I'm looking for?

Thanks in advance.

You don't need a regex for this. Check this answer: https://stackoverflow.com/a/8224726/3151675 — Tamás Sengel, Jul 10 '18 at 12:52

You Can Use this: e.x.http://www.xn--vi8hiv.ws/

+ (BOOL) urlIsValiad: (NSString *) url
{
    NSString *regex =
    @"((?:http|https)://)?(?:[A-Za-z0-9]{1,25}\\.)?[\\w\\d\\-_]+\\.\\w{2,3}(\\.\\w{2})?(/(?<=/)(?:[\\w\\d\\-./_]+)?)?";
    NSPredicate *regextest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex];

   if ([regextest evaluateWithObject: url] == YES) {
       NSLog(@"URL is valid!");
   } else {
       NSLog(@"URL is not valid!");
   }
   return [regextest evaluateWithObject:url];
}

Thanks Ketan Odedra, but I have tried this and still not working – Asneroll Jul 10 '18 at 13:23
can you show me which url are you using? – Ketan Odedra Jul 10 '18 at 13:25
It's just below my code: http://.la – Asneroll Jul 10 '18 at 13:29
its same url " http://xn--ls8h.la/ " and it is valid.i checked it – Ketan Odedra Jul 10 '18 at 13:35
Maybe it is working for you because you are turning emojis into text. I'm trying with and without http, https, www, and your code is not working for me. – Asneroll Jul 10 '18 at 14:25
