You can use quantity property in SKPayment... Read how many items you want from user then pass this value to payment.quantity(By default it is 1).

SKPayment *payment = [SKPayment paymentWithProductIdentifier:inProductID];
payment.quantity = mNoOfItemsYouWant;
[[SKPaymentQueue defaultQueue]addTransactionObserver:mTransactionObserver];
[[SKPaymentQueue defaultQueue] addPayment:payment];

Each purchase needs authorization from the user, so I don't think you can do what you want to.

However, you can make a single in-app purchase which is priced and behaves like multiple items clubbed together. For instance:

• Item 1 - $.99
• Item 2 - $.99
• Item 3 - $.99
• Bundle (includes 1, 2, 3) - $1.99
