购买非消耗类型的物品后，调用初始化后.就会进入交易成功.

购买非消耗类型的物品后，重新启动应用。 调用初始化后.就会进入交易成功的状态是为什么？

[itenfay]

付款完成，交易票据验证通过拿到server响应后，客户端要调用以下方法关闭此次交易，不然每次启动苹果server会通知客户端还有交易未完成，另外非消耗产品需要提供额外的恢复购买的按钮提供用户使用。

// Completes a pending transaction.
[DllImport("__Internal")]
private static extern void DYFFinishTransaction(string transactionId, string originalTransactionId);

// Completes a pending transaction.
[DllImport("__Internal")]
private static extern void DYFFinishTransaction_(string transactionId);

我在验证成功之后调用的关闭交易，调用了关闭交易还是存在这个问题。 无法正确的关闭时因为transactionId不正确么，我在恢复购买后，进行验证。然后再下行信息里拿到的transactionId和 初始化后弹出的交易里的transactionId并不一样。但是他们的originalTransactionId是一样的。当然他们都是同一个商品。

你看一下 UnityIAPConnector.mm 文件这段代码。因为非消耗型产品，在恢复购买后，transactionId与之前不一样，但originalTransactionId是一样的，导致传新的transactionId找不到Restored transaction。

/// Completes a pending transaction.
void DYFFinishTransaction(const char* transactionId, const char* originalTransactionId)
{
    NSString *transactionIdentifier = __OBJC_STRING(transactionId);
    NSString *orgTransactionIdentifier = __OBJC_STRING(originalTransactionId);

    DYFStore *store = DYFStore.defaultStore;
    SKPaymentTransaction *pt = [store extractPurchasedTransaction:transactionIdentifier];
    if (pt) {
        [DYFStore.defaultStore finishTransaction:pt];
    } else {
        SKPaymentTransaction *rt = [store extractRestoredTransaction:transactionIdentifier];
        [DYFStore.defaultStore finishTransaction:rt];
    }
    DYFStoreUserDefaultsPersistence *persister = [[DYFStoreUserDefaultsPersistence alloc] init];
    [persister removeTransaction:transactionIdentifier];

    if (orgTransactionIdentifier) {
        [persister removeTransaction:orgTransactionIdentifier];
    }
}

[itenfay]

- (SKPaymentTransaction *)extractRestoredTransaction:(NSString *)transactionIdentifier
{
    __block SKPaymentTransaction *transaction = nil;
    if (!transactionIdentifier || transactionIdentifier.length == 0) {
        return transaction;
    }

    [self.restoredTranscations enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        SKPaymentTransaction *tempTransaction = obj;
        NSString *id = tempTransaction.transactionIdentifier;
        NSString *originalId = tempTransaction.originalTransaction.transactionIdentifier;
        DYFStoreLog(@"index: %zi, transactionId: %@, originalTransactionId: %@", idx, id, originalId);

        if ([id isEqualToString:transactionIdentifier]) {
            transaction = tempTransaction;
        }
    }];

    return transaction;
}

你过滤一下日志，看一下这段代码的日志打印的是什么，在这里回复我一下，我看到后分析定位问题所在，然后进行修复。

这里是log，初始化后processPurchaseNotification这里收到的是DYFStorePurchaseStateSucceeded，而不是Restore

1. 红框标记和下面遍历Purchased Transcations都对得上。
2. 看完log，发现调用完成交易的方法传入的交易id是null或是空的，你看下C#那边传的参数什么？

3. 调用完成交易会进入下面的方法，检查一下交易id和原始交易id。

   /// Completes a pending transaction.
   void DYFFinishTransaction(const char* transactionId, const char* originalTransactionId)
   {
   NSString *transactionIdentifier = __OBJC_STRING(transactionId);
   NSString *orgTransactionIdentifier = __OBJC_STRING(originalTransactionId);
   
   DYFStore *store = DYFStore.defaultStore;
   SKPaymentTransaction *pt = [store extractPurchasedTransaction:transactionIdentifier];
   if (pt) {

    }
}

调用传入的transactionIdentifier是正确的，最后的log是在这里输出的。 这里使用的值是 传入的SKPaymentTransaction中的字段 ，如果在上一步没有找到正确的SKPaymentTransaction这里就会出现空的字符串。和C# 传入的值没关系。
