Question

我已经成功使用AWS SDK框架，现在我正在尝试将静态库导入为自制框架，与我的其他几个项目共享代码。

问题是：为了导入我的静态库，我need to add -ObjC链接器标志以便导入库，但每当我添加该链接器标志时，AWS 就吓坏了并且给了我40多个红色编译错误。

我对链接器标志和库导入完全不熟悉，所以老实说我真的不知道从哪里开始。我已经完成了一些研究，但我能找到的最好的主要建议是我可以使用-force_load而不是-ObjC，但这似乎需要在Build中手动添加每个“.m”文件阶段部分，我的库包含数百个这样的文件。

是否有一个更简单的解决方案来解决这个问题，而不是添加其中的每个文件，以便我可以使用-force_load？我怎样才能获得AWK SDK以及导入我的库以便一起玩的需要？

编辑：根据评论中的建议，这是我添加-ObjC链接器标志时出现的错误。如果没有该标志（并且没有添加静态库），该应用程序将成功编译AWSiOSSDKv2框架。但添加链接器标志（据我所知，静态库需要，但即使在添加该库之前）也会立即导致：

[已删除代码以符合字符数限制]

编辑2：根据松田洋介的回答，我添加了libsqlite3.dylib，我失踪了。现在先前的错误已经消失，但我有几十（数百？）个“重复符号”行，以单个红色“链接器命令失败并退出代码1”错误结束。（我会把它们全部包括在内，但是，他们非常热闹，我的帖子是73,111个字符，超过了30,000个字符限制。）

有趣的是，它们似乎来自框架本身要求引起的冲突（例如，AWS框架中的AWSCore需要Bolts框架，但它们似乎与一堆冲突重复的符号？）。

而且，和以前一样，只需从链接器标志中删除-ObjC即可让应用程序正常并成功编译。

适用于iOS的AWS Mobile SDK依赖于libsqlite3.dylib，libz.dylib和SystemConfiguration.framework，但您未提供这些内容。这是错误消息的原因。 AWS Mobile SDK for iOS Developer Guide的这一部分列出了必要的依赖关系。
