ios - 无法重现 iOS App Review 团队崩​​溃。使用 Vuforia 的 Unity 应用程序

Question

我们最近提交了两个应用程序(一个新应用程序，一个是已发布应用程序的更新)，但由于以下原因，这两个应用程序被 iOS 应用程序审查小组拒绝了:

Guideline 2.1 - Performance Your app crashed on iPad or iPhone running iOS 11.2.5 connected to an IPv6 network during our review.

在提交应用程序之前，我们使用 testflight 在 4 种不同的设备和 iOS 版本上对它们进行了广泛的测试，并且没有遇到任何崩溃。我们无法重现 iOS 应用审查团队的崩溃体验

我们的开发环境对于这两个应用程序是相同的，这可能是崩溃的原因:Unity 2017.2.1f1 与 Vuforia(这是一个增强现实应用程序)，Xcode 9.2(最新版本)

之后你会发现新应用程序的崩溃日志，(更新后的应用程序有相同的崩溃日志......)，它们非常相似:

The two crashlogs are very similar :

由于我们无法重现崩溃，因此很难修复。在此崩溃日志中有一些关于 SplashScreenController 的内容，以防万一我们删除了启动画面，并将 Unity 版本更改为 2017.3.1 并重新提交了应用程序...

真的很感激任何帮助，也许我们在崩溃日志中遗漏了一些有用的信息？

我们遇到了同样的问题(同样的异常和应用商店拒绝)。我们遇到了这个似乎是罪魁祸首的 Unity 错误。

https://issuetracker.unity3d.com/issues/ios-11-build-crashes-on-remotear-unityupdatedisplaylist-when-launching-app-from-url-with-airplay-connected

当用户流式传输他们的设备屏幕(AirPlay 等)时，有一个错误会导致崩溃。我假设测试人员有时会使用 AirPlay 导致崩溃，而开发人员却没有发现任何问题。

幸运的是，此错误已在 Unity 中得到纠正，并已向后移植到多个 Unity 补丁版本:

固定在:2018.1.0b1

反向移植到:2017.3.0p22017.2.1p22017.1.3p1

从2017.2.1更新到2017.2.1p2后，我们的应用被接受了。
