In app purchases restore Button

I use a variation of this:

//inside of an IBaction[[SKPaymentQueue defaultQueue] addTransactionObserver:self];[[SKPaymentQueue defaultQueue]restoreCompletedTransactions];// Then this is called- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {    NSLog(@"%@",queue );    NSLog(@"Restored Transactions are once again in Queue for purchasing %@",[queue transactions]);      NSMutableArray *purchasedItemIDs = [[NSMutableArray alloc] init];    NSLog(@"received restored transactions: %i", queue.transactions.count);    for (SKPaymentTransaction *transaction in queue.transactions) {        NSString *productID = transaction.payment.productIdentifier;        [purchasedItemIDs addObject:productID];        NSLog (@"product id is %@" , productID);        // here put an if/then statement to write files based on previously purchased items        // example if ([productID isEqualToString: @"youruniqueproductidentifier]){write files} else { nslog sorry}    }  }

Sorry, I'm on my iPad if this makes no sense.

Alex, i've been rejected for the same reason last week, and this is right what Apple wanted - after adding such a Restore button they didn't ask any other question on this subject.

Of course, you need not only to call [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];, but implement the restoring itself too (i mean, providing the content to user).

This is because you can be signed in with the same Apple ID on different iOS devices.

For example, let's say I'm logged into test@iCloud.com on an iPad. When I download your application, I realize that I would like to remove the ads, so I pay 99¢ to remove them.

A year later, I decide to buy an iPhone, and sign into test@iCloud.com on that account, and I download your app again. However, the ads are still there, even though I already paid to remove them on my iPad. That's where the restore feature comes in. Using that, I can restore the purchases that I made on my iPad, and make them work on my iPhone.

To restore the purchase, you could use:

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

This causes the

(void) paymentQueueRestoreCompletedTransactionsFinished: (SKPaymentQueue *)queue

method to be called. Inside of that, you need to provide the user with the content that they bought.
