   };
   LKGameCenterNameToIdentifierTranform = ^NSString *(NSString *name){
      return [@"scores." stringByAppendingString:name];

    if (!account) {
        account = [[LKGameCenter alloc] init];
        [[LeaderboardKit shared] addAccount:account];
    }

    [account requestAuthWithViewController:self success:^{
        [[[UIAlertView alloc] initWithTitle:@"Success" message:@"GameCenter account connected" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
    } failure:^(NSError *error) {

   }];

       id<LKAccount> account = [[LKTwitterAccount alloc] initWithUserRecord:[LeaderboardKit shared].userRecord];
       [account requestAuthWithViewController:self success:^{
           [[LeaderboardKit shared] setAccount:account forIdentifier:LKAccountIdentifierTwitter];
