在我们的测试设备(iPhone 4S、5 和 6 Plus)上，应用程序运行良好，但是当我将构建发送到客户端时，应用程序开始在 4 台设备中的 2 台上崩溃。
下面我粘贴了曲棍球的崩溃日志，但我无法找到崩溃的原因。
请帮我找出崩溃的原因。
谢谢

最佳答案
从跟踪来看，当您在 8.1.2 OS 版本的 iPhone 5S ( as per the hockey docs ) 上执行一些通讯录操作时，应用程序似乎崩溃了
您可能会询问客户端它在哪个模块上崩溃以及产生崩溃的步骤是什么。
始终向客户端提供在您支持的最新和最低版本的操作系统上测试的构建，使用更好的崩溃报告库，它提供崩溃的完整详细信息，如 crashlytics (只是一个例子)。
当设备内存不足时，我们可能会出现奇怪的崩溃，这也可能是原因之一。
