iPhone:如何找到不常见的设备崩溃？

我的源代码项目很少发生崩溃.虽然我试图重复这么多次,但我找不到完全可重复的步骤.在dubug上设备变得非常难以重现它,因为它发生在某个地方,有时候.在iPhone Xcode开发中,是否有任何日志打印,同时崩溃设备(或)任何其他工具/方式以确切地找出它可能发生的位置？

感谢并感谢您对此的帮助.

这是我的应用程序最新崩溃:有人找到任何理由吗？

您应该能够获得崩溃日志.

在崩溃日志中,您将获得应用程序崩溃时发生的事件的堆栈跟踪.

查看堆栈跟踪,了解您正在做的最后一件事.跟踪中的最后一件事可能在您调用的框架方法中,因此将回调跟踪回代码并将其作为起点.

一旦你知道代码在崩溃发生的位置,试着想一想可能导致崩溃的原因.如果您在查看可能导致崩溃的原因时遇到问题,请在此处发布导致崩溃的行(以及环绕声代码),我们可能会对导致崩溃的原因有所了解.
