Question

我正在为我的iOS应用程序购买应用程序。由于没有恢复购买的产品，Apple拒绝了我的二进制文件。在我的应用程序中，一旦用户点击产品图标，如果项目被锁定，他/她将指向inApp购买流程，否则产品将开启。没有可视购买按钮。现在苹果说要提供恢复按钮？谁能告诉我如何处理这个问题？我试过了

- (void) checkPurchasedItems
{
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}// Call This Function

//Then this delegate Function Will be fired
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
    alreadyPurchasedItems = [[NSMutableArray alloc] init];

    NSLog(@"received restored transactions: %i", queue.transactions.count);
    for (SKPaymentTransaction *transaction in queue.transactions)
    {
        NSString *ID = transaction.payment.productIdentifier;
        [alreadyPurchasedItems addObject:ID];
    }

}

在应用程序启动时，从不调用paymentQueueRestoreCompletedTransactionsFinished方法，以便我可以获取已购买项目的列表，然后直接通知用户他/她是否已购买此项目。

如何设置[SKPaymentQueue defaultQueue]的代理？我猜你已经像smt一样：

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

之后[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];会导致以下方法被触发。因此，SKPaymentTransactionStateRestored就是您实现它的地方：

-(void) paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction * transaction in transactions) {
        switch (transaction.transactionState)
        {
            case SKPaymentTransactionStatePurchased:                
                ...
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:                
                ...
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:                
                ...
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            default:
                break;
        }
    };
}
