Question

当我尝试编译我的项目时，我收到错误。我添加了所有必需的框架 - AVFoundation，opencv和许多其他框架，但它对我没有帮助。这个错误有几行：

     Undefined symbols for architecture i386:

  "_OBJC_CLASS_$_AVCaptureDevice", referenced from:
      objc-class-ref in MACaptureSession.o

Answer 1

添加 <{1}}和CoreMedia.framework到您的项目。

得到。

项目 - ＆gt;目标 - ＆gt;构建阶段 - ＆gt;链接二进制文件库 - ＆gt; ＆＃34; +＆＃34; - ＆GT;选择你的框架

Answer 2

检查一下 MACaptureSession MAImagePickerFinalViewController MAImagePickerControllerAdjustViewController MAImagePickerController.m 已添加到目标并检入相应的m文件，实现名称是正确的。

Answer 3

正如Mani所建议的，添加必需的框架。如果您已添加这些框架但仍然收到错误，请在项目的构建设置下将Build Active Architecture Only设置为NO。
