Question

在我的项目中我需要外国SDK。第一个sdk始终使用标志-ObjC和-all_load，第二个不需要这些标志。如果我为第二个sdk设置了两个标志，我会收到一些重复符号消息。如果我删除了标记，则第一个sdk会将错误无法识别的选择器发送给实例。

如何解决此问题？有没有办法说标志-ObjC和-all_load从第二个sdk中排除？

编辑：第一个sdk是dropbox iOS sdk，它安装在pod上，需要标志-ObjC和-all_load。

第二个sdk有一些.h和.m文件和一个链接库libMTProtocol.a。

如果在其他链接器标志中启用了标志，则会收到以下重复消息：

duplicate symbol _OBJC_CLASS_$_MTExchangeDataThermoFrameFactory in:

duplicate symbol _OBJC_IVAR_$_MTExchangeDataThermoOutputMessage._mode in:
ld: 26 duplicate symbols for architecture arm64

所有重复的符号都是libMTProtocol.a库中的引用。

两个sdk的不同的其他链接器标志
