App rejected for not having "Restore" Purchases feature

Question

My app was rejected for not implementing "Restore Purchases" feature.

Apple says

We found that your app offers In-App Purchase/s that can be restored but it does not include a "Restore" feature to allow users to restore the previously purchased In-App Purchase/s. To restore previously purchased In-App Purchase products, it would be appropriate to provide a "Restore" button and initiate the restore process when the "Restore" button is tapped.

So I finally decided to add that and I found we have to use

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

But it doesn't help! I searched for similar questions but found none working for my app. These are the following links that I have stacked so far :

Restore already bought in-app-purchases on iPhone?

iOS6 - In app purchase with download from Apple server

Please help!! Thanks in advance..

Answer 1

Try the following :

On Restore button click -->

- (IBAction)retoreinApp:(id)sender
{
    //set  addTransactionObserver to self. 
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

}

This will call

- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {

    UIAlertView *alert ;
    if(queue.transactions.count >0)
    {
        for (SKPaymentTransaction *transaction in queue.transactions)
        {
            NSString *productId = transaction.payment.productIdentifier;

          NSLog(@" ProductIdentifier is %@",productId);
            if([productId isEqualToString:@"com.xy.yourProductId"])
            {//add code to add it to your account
             }
          alert = [[UIAlertView alloc ] initWithTitle:@"Restore Transactions" message:@"All your previous transactions are restored successfully." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];

  }
    else
    {
        alert = [[UIAlertView alloc ] initWithTitle:@"Restore Transactions" message:@"No transactions in your account to be restored." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];

    }
    [alert show];

}
