遇到的问题 ( What's the issue? )

有一个对象，在单元测试的时候插入和读取数据都没有问题，在第三方调用的时候，每次都崩溃。调用堆栈如下：
`* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x0)

检查下 podfile 有没有加 use_framework!
然后麻烦提供下完整的 crash 堆栈 或 能够重现 crash 的代码

[xmkevin]

找到问题的原因了，是因为我在一个 Workspace 下，有三个项目。A-->B--->C-->WCDB，A 是一个 iOS App, B 是一个静态库，C 是一个动态库，因为 B 和 C 是一个慢慢融合的过程，现在 B 和 C 都依赖 WCDB，导致我在Pod 中 A 依赖的WCDB， C 也依赖了 WCDB，这样就出问题了。

[RingoD]

@xmkevin 所以这就是我不那么推荐 cocoapods 的原因，静态库比较容易出问题
