                break;

            case SKPaymentTransactionStatePurchased:

                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                // remove wait view and unlock feature 2

附上案例

示例：

    switch (transaction.transactionState)
    {
        case SKPaymentTransactionStatePurchasing:
            {
                //[self completeTransaction:transaction];
                // show wait view here
                statusLabel.text = @"Processing...";
                break;
            }
        case SKPaymentTransactionStateFailed:
            {
                // another case contents
                break;
            }
    }
