我试图将此project包含在我的swift中。这个项目使用ffmpeg播放器。所以我把整个文件拖到我的项目下面。我有很多编译时错误，我解决了它们。最后我收到链接器错误。这些是错误：

据我所知，这些是.a文件中的错误。当我运行原始项目时运行正常，但当我将其包含在我的项目中时，我收到了这些错误。我该如何解决这些错误？

需要添加一些dylib框架。 添加＆＃34; libz.dylib＆＃34;来自目标的框架 - ＆gt; Build Phases选项卡 - ＆gt;链接二进制文件与库， 你可以通过错误键搜索框架 希望这对你有用。

如果有人在Unity 2019.3+中构建到Xcode 11.5+，并且出现Mach-O-Link错误或_inflate错误或链接失败，则将对其进行修复。但是，请记住将libz.tbd添加到UnityFramework Targets条目中，然后转到BuildPhases>'Link Binary with Libraries'。然后在顶部添加libz.tbd文件，将其添加到UnityFramework Target中。这对我来说是固定的。
