ios - Objective-C NSUnknownKeyException setValue :forUndefinedKey:

Question

在我将 xcode 升级到新版本 (6.0.1) 之后，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”导出引用，但在我的情况下，当我从 sqlite 数据库获取数据时会发生。我使用 FMDB 和 BZObjectStore 库来处理我的数据库。

这是我的控制台输出:

Answer 1

我已经发布了 BZObjectStore 1.3.13。

你能运行'pod update'然后重试吗？

谢谢
