【问题描述】：
在我将 xcode 升级到新版本 (6.0.1) 后，我在运行我的应用程序时遇到了 NSUnknownKeyException。
四处寻找解决方案，我发现这个问题通常出现在 xib 中的“死”出口引用，但在我的情况下，当我从 sqlite 数据库获取数据时发生。我使用 FMDB 和 BZObjectStore 库来处理我的数据库。
这是我的控制台输出：

提前感谢您的帮助。
【问题讨论】：
-
感谢您的崩溃日志。但是代码在哪里？
-
您是否有名为
hash或类似名称的列？ -
@Kampai 我没有粘贴代码，因为崩溃不在我的代码中，而是在库中。
-
@Tommy 是的，有一个“哈希”列。我会对此进行调查
-
已解决。这是 bzobjectstore 库中的一个错误
