我使用Crashlytics 3.6.0并且我最近收到了一些我无法阅读/理解的崩溃报告。它们似乎只发生在iOS 8上（但不能确认这100％）。

有人可以帮我识别错误吗？我无法重现错误 - 它不会发生在我的设备或模拟器上。但是在过去的几天里，我从测试用户那里得到了相当多的崩溃报告。
答案 0 :(得分：0)
这是仅在iOS 8上发生的错误。要重现错误，我下载了iOS 8.1模拟器并发现错误。为了获得确切的错误消息，我去了Edit Scheme和Enabled Zombie Objects。这向我展示了确切的错误信息：
*** -[NamedUISwitch _sendActionsForEvents:withEvent:]: message sent to deallocated instance
