You can use this method:

- (BOOL) validateUrl: (NSString *) url {
   NSString *theURL =
   @"(http|https)://((\\w)*|([0-9]*)|([-|_])*)+([\\.|/]((\\w)*|([0-9]*)|([-|_])*))+";
   NSPredicate *urlTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", theURL]; 
   return [urlTest evaluateWithObject:url];
   }
