【问题描述】：
我收到报告称，当用户尝试更新我在应用商店中的应用时，该应用尝试使用新版本打开，但随后崩溃。重复此过程，直到用户从手机中删除该应用程序并进行全新安装。我已经掌握了其中一个崩溃日志，但是后面的跟踪让我几乎没有继续下去。
更新不应该像全新安装应用程序一样吗？更新如何导致崩溃但全新安装不会？以前版本中不应有可能导致崩溃的残留数据。
我看到另一个有类似问题的人：iOS crash log, backtrace not available

【问题讨论】：
-
您是否有机会使用 CoreData 并且您是否更改了模型？还要添加崩溃日志的任何信息，否则应该如何帮助您？
-
1) 是的，有CoreData，是的，模型已经改变。但是如何防止在更新时发生崩溃？ 2）我将编辑我的问题以涉及崩溃日志
-
“不应该有以前版本的残留数据”——这完全不正确！所有用户的数据，包括他们的
NSUserDefaults以及您放在 Documents 目录中的任何内容，都会从一个版本保存到另一个版本。
