写在前面：对于开发企业级应用的开发者而已，以资源文件的形式来加载动态库就显得尤为重要，因为，给不同的客户打不同的IPA包，里面的有些功能是不一样，比如说有一个动态库是专门为一个客户制定的，那么在给其他客户打包时就不应该把这个动态库打进去。所以，为了解决这个问题，我们可以使用下面的这种加载方式。
1.添加动态库到资源

然后，选择你刚才放在主工程目录下的动态库。这时项目目录下多了一个动态库。倘若你之前直接拖进来时目录下就已经存在，请先右键删除引用。
2.动态加载动态库
直接上我项目中实际使用的代码：
这个动态库主要实现的是一个视频会议的功能
这个TBConfMeetingApi类是我处理这个创建会议和加入会议的一个工具类
