How to add Tag to perform different Get methos for contact view Picker?

[DheerajKaveti1]

I would like to do some thing like this below, could any one help me out in acheving it.

• (void)contactPickerTextViewDidChange:(NSString *)textViewText {

  [self.contactPickerView becomeFirstResponder];
  NSString *sql;

  if ([textViewText isEqualToString:@""]){
  }
  else {

if(contactpicker.tag==1)
sql = [NSString stringWithFormat: @"Select id, Name, lastname, firstname ORDER BY lastname LIMIT 25", textViewText,textViewText,textViewText];
NSLog(@"%@",sql);

if(contactpicker.tag==2)
sql = [NSString stringWithFormat: @"Select id, Name, lastname, firstname ORDER BY lastname LIMIT 25", textViewText,textViewText,textViewText];

    NSLog(@"%@",sql);

SFRestRequest *request = [[SFRestAPI sharedInstance] requestForQuery:sql];
[[SFRestAPI sharedInstance] send:request delegate:self];

    //self.filteredContacts = [self.contacts filteredArrayUsingPredicate:predicate];
}
[self.tableView reloadData];

}
