【中文标题】应用程序拒绝 - 崩溃报告说：未能及时创建场景 (badf00d) 出了啥问题？【英文标题】：App rejection - Crash report says: failed to scene-create in time (badf00d) What is wrong?应用程序拒绝 - 崩溃报告说：未能及时创建场景 (badf00d) 出了什么问题？ 【发布时间】：2015-01-05 19:30:34 【问题描述】：我的应用刚刚被苹果拒绝，我可以通过一些帮助来找出问题所在。该应用程序在我所有的设备上都可以正常运行，并且不会崩溃。该应用程序在启动时立即与 iCloud 同步。这在我的设备上运行良好，但也许有问题。
这是第一个崩溃报告（符号）：

【问题讨论】：
我尝试上传到 Test Flight 的应用程序遇到了完全相同的问题。在我尝试的每台设备上都可以正常工作，但被 Apple 拒绝并且崩溃日志显示“未能及时创建场景” - 我尝试在我的设备上以飞行模式运行，但它仍然可以正常启动。 你也用icloud吗？ 是的，使用 Tim Roadley Core Data 教程（所以大部分代码都来自那本书）。我确实将 CJPAdController 框架更新到 1.6.1（其中特别提到了线程更新），并且该应用刚刚获得批准！ 酷。我认为我的问题是我刚刚将 xcode 更新到 6.0 并将我的设备更新到 8.0。这也让我使用了仅适用于 8.0 的 cloudkit，但我的开发目标是 7.1，因此它不起作用。我认为这就是它崩溃的原因，我正在等待审核我的新版本。 【参考方案1】：问题很简单。 你只是花太多时间在启动屏幕上加载你的应用程序，ios 设备就会停止你的应用程序。 它只发生在审查中而不是在您测试时发生的原因是因为您总是从 Xcode 运行它，而从 Xcode 运行它不会有这种行为。 如果您将直接从设备运行您的应用程序（通过点击其图标），您将看到它也会在那里发生。假设您在该特定运行上花费了太多时间。
编辑：我还看到您被困在信号量上并且没有使用太多 CPU，这可能意味着您遇到了死锁，导致应用程序在审阅者的设备上停止运行，这就是它花费太多时间加载的原因并且设备会停止您的应用程序。不确定...

【讨论】：
正如我上面写的，我想我找到了问题所在。我在仅适用于 ios 8.0 的应用程序中使用 cloudkit。我的应用程序针对 7.1。当我在装有 ios 7.1 的设备上运行该应用程序时，它没有启动。 问题是您的应用程序在加载屏幕中停顿的时间过长。但是您可能已经找到了导致该停顿的原因。无论如何，您在日志中遇到的错误表明您的应用由于停顿时间过长而被踢到了加载屏幕 以上是问题所在。刚刚获得批准！ 谢谢@user1097185，您提到的链接帮助我从设备获取日志文件，使用它我了解启动屏幕所需的 CPU 时间并减少进程，现在可以正常工作:) @user1097185 您提供的链接已失效。以上是关于应用程序拒绝 - 崩溃报告说：未能及时创建场景 (badf00d) 出了啥问题？的主要内容，如果未能解决你的问题，请参考以下文章
