我通过 Testflight 分发了我的应用程序：该应用程序在运行 iOS 9.2.1 的 iPhone 6s 上启动几秒钟后崩溃。
但是在 iPhone 6s - 9.2.1 设备上使用 Xcode 安装应用程序时，一切正常。
当使用 Xcode 启动应用程序并通过 Testflight 在运行最新 10.3.2 的其他 iPhone 6s 上分发我的应用程序时，一切正常。
如果我测试 wia testflight ios 9.2.1 应用程序每次都会随机 崩溃。崩溃日志在每次崩溃时向我显示绝对不同的原因
我们正在使用 Crashlytics，它报告了超过800次崩溃，每一次都是单个崩溃，指向内部苹果框架或私有 API。我们的代码上有一些崩溃点。
大多数生成的错误是：
