应用程序拒绝 - 崩溃报告说:未能及时创建场景(badf00d)有什么问题？

Question

我的应用程序刚被苹果拒绝,我可以帮助找出问题所在.该应用程序在我的所有设备上运行正常,并且不会崩溃.该应用程序在启动时与iCloud同步.这在我的设备上工作正常,但也许有些东西可以解决.

这是第一个崩溃报告(符号化):

如果您需要其他信息,请告诉我们.

Answer 1

问题很简单.您只需花费太多时间在启动画面上加载您的应用,iOS设备就会停止您的应用.它只发生在评论中,而不是在测试它的原因是因为你总是从Xcode运行它,并且从Xcode运行时它不会有这种行为.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.假设您在特定运行中花费了太多时间加载.

编辑:此外,我发现你被困在一个信号量,并没有使用太多的CPU,这可能意味着你有一个死锁,在审稿人的设备上停止应用程序,这就是为什么它花费太多时间加载和设备停止你的应用程序 不确定...
