iPhone應用程序崩潰日志—如何使用它們調試我的應用程序？

Question

我一般不是編程專家。 我可以在Objective-C和Xcode周圍找到自己的方式，並構建沒有大問題的可運行應用程序，但是當出現BUG時，我通常會迷失從哪里開始。

我的應用程序在SIM卡上運行正常，但比正常情況下崩潰的原因是它在設備上崩潰了。 我查看了崩潰日志，以查看是否有任何線索可以開始，但是這些東西已經超出了我的腦海。 如何在調試中開始使用THIS和將來的崩潰日志？ （下面的崩潰日志）

Answer 1

當應用在設備上崩潰時，設備將不知道代碼庫以及您使用的標識符（變量名，方法名等）。 因此，與其給您看似友好的方法名稱和發生崩潰的行號，不如給您提供相關的內存地址。

我相信有一些工具可以幫助您將內存地址反轉為可識別的地址。 看到類似問題的 Google搜索 。
