我在Swift项目中添加了FMDB并遵循FMDB Swift指令（即复制相关的.h / m。文件并创建包含import语句的桥接头）。当我尝试编译时，我得到了大量的错误，所有这些都是Apple Match-O-Linker错误......

我添加的FMDB文件是：
FMDatabase.h
FMDatabase.m
FMDatabaseAdditions.h
FMDatabaseAdditions.m
FMDatabasePool.h
FMDatabasePool.m
FMDatabaseQueue.h
FMDatabaseQueue.m
FMDB.h
FMResultSet.h
FMResultSet.m
有人可以告诉我我做错了吗？

没关系任何人！我解决了我必须通过项目设置中的Build Phases页面将libsqlite3.dylib链接到我的项目中。到目前为止，我的项目中没有框架组，因此有点令人困惑。
答案 1 :(得分：0)
您的项目 - ＆gt;一般 - ＆gt;链接的框架和库您可以添加此libsqlite3.0.tbd。 现在可以构建您的项目和框架。
