我需要一些关于此崩溃日志的帮助。我已经看到有关此错误的其他帖子与看门狗超时有关，但我无法弄清楚这一点。

吃坏食物（ 0x8badf00d ）是指看门狗杀死你的应用程序，因为它需要太长时间才能启动。您的应用程序：didFinishLaunchingWithOptions：方法必须在不到5秒内完成，否则Watch Dog会咬你。 注意：当您在调试器中运行时，看门狗被禁用。在提交到App Store之前，您必须在设备上测试发布版本。要修复此错误，您需要使用Time Profiler在Instruments中的设备上运行App。
你应该观看WWDC 2012 Session 225 Up and Running - 每次发布都会给人留下深刻的印象。它演示了如何修复此错误。 https://developer.apple.com/videos/wwdc/2012/?id=225
