在 iOS 上获取 IAP 产品的空标题和描述

Question

在我的应用程序获得 App Store Connect 批准之前，一切正常。

当我的 IAP 处于“准备提交”状态时，我的产品就很好了。但现在，它处于“已批准”状态，我的产品标题和描述都是空的。价格和标识符都可以。

即使在使用 Magic Weather example app from RevenueCat 时我也遇到了同样的行为。

这是我的代码：

Future<void> _initPlatformState() async {
    await Purchases.setup("******************************", appUserId: null);
    Purchases.addPurchaserInfoUpdateListener((info) {
      _checkIfVIP(info);
    });
    try {
      purchaserInfo = await Purchases.getPurchaserInfo();
      print('PurchaserInfo: ' + purchaserInfo.toString());
      //_checkIfVIP(purchaserInfo);
    } on PlatformException catch (e) {
      print('PlatformException: ' + e.toString());
    }
    print('is user vip? ' + isVIP.toString());
  }

  void _checkIfVIP(PurchaserInfo purchaserInfo) {
    if (purchaserInfo != null && purchaserInfo.entitlements.all['vip'] != null) {
      setIsVIP(purchaserInfo.entitlements.all['vip'].isActive);
    } else {
      setIsVIP(false);
    }
    notifyListeners();
  }

  Offerings _offerings;

  Future<Offerings> getOfferings() async {
    Offerings offerings;
    if (_offerings != null)
      offerings = _offerings;
    else {
      try {
        offerings = await Purchases.getOfferings();
      } on PlatformException catch (e) {
        print(e.toString());
      }
    }
    print(offerings.toString());
    return offerings;
  }

和

Future<void> doPurchase() async {
    try {
      if (_offerings != null) {
        _toggleLoadingState();
        PurchaserInfo purchaserInfo = await Purchases.purchasePackage(_offerings.current.monthly);
        // the native purchase window should open before going forward
        if (purchaserInfo.entitlements.all["vip"].isActive) {
          MainModel mainModel = Provider.of<MainModel>(context, listen: false);
          mainModel.setIsVIP(true);
          showDialog(
            context: context,
            builder: (BuildContext context) {
              return AlertDialog(
                title: new Text(S.current.welcome_to_the_vip_group),
                content: new Text(
                  S.current.purchase_success,
                  textAlign: TextAlign.center,
                ),
                actions: <Widget>[
                  new TextButton(
                    child: new Text(S.current.close),
                    onPressed: () => {popToPreviousPage(context)},
                  ),
                ],
              );
            },
          );
        } else {
          print('purchaserInfo.entitlements.all["vip"].toString());
          _toggleLoadingState();
        }
      }
    } on PlatformException catch (e) {
      _toggleLoadingState();
      var errorCode = PurchasesErrorHelper.getErrorCode(e);
      showDialog(
        context: context,
        builder: (BuildContext context) {
          if (errorCode == PurchasesErrorCode.purchaseCancelledError) {
            return AlertDialog(
              title: new Text(''),
              content: new Text(
                S.current.purchase_canceled_error,
                textAlign: TextAlign.center,
              ),
              actions: <Widget>[
                new TextButton(
                  child: new Text(S.current.close),
                  onPressed: () => Navigator.pop(context),
                ),
              ],
            );
          } else if (errorCode == PurchasesErrorCode.storeProblemError) {
            return AlertDialog(
              title: new Text(S.current.oops),
              content: new Text(S.current.purchase_store_problem_error(Platform.isAndroid ? 'Google Play' : 'App Store')),
              actions: <Widget>[
                new TextButton(
                  child: new Text(S.current.close),
                  onPressed: () => Navigator.pop(context),
                ),
              ],
            );
          } else {
            return AlertDialog(
              title: new Text(S.current.oops),
              content: new Text(S.current.purchase_default_error),
              actions: <Widget>[
                new TextButton(
                  child: new Text(S.current.close),
                  onPressed: () => Navigator.pop(context),
                ),
              ],
            );
          }
        },
      );
      print('isLoadingSomething = ' + e.toString());
    }
  }

在 Android 上一切都很好，在 App Store Connect 上似乎一切都很好。

我也在他们的 github 页面 (here and here) 上报告了这个问题，但没有任何帮助。

知道会发生什么吗？我什至尝试更改我的产品标题以查看是否可以修复它，但没有成功。

数周以来一直在苦苦挣扎。不知道怎么办了。

Answer 1

原来 flutter SDK 上的某些内容已损坏。我删除并重新下载了flutter SDK，它成功了。

奇怪。
