我在我的项目中使用 AFNetworking 和另外 2 个使用 cocoapods 的框架，现在我想在同一个项目中添加 opencv2.framework
这样做有什么不同的技术吗？ 因为当我在我的项目(已经使用 cocoapods)中添加 opencv2.framework 时，它显示错误:

但是当我在没有 cocoapods 的新项目中使用 opencv2.framework 时它工作正常
最佳答案
将您的项目链接到 CoreMedia 框架。而且似乎还必须添加 AVFoundation
关于ios - 使用 Cocoapods 添加另一个框架，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35846637/
