方法一:
只能录制iOS页面,unity页面为黑屏
方法二:
类似于方法一
方法三:
Unity3D研究院之IOS截屏 话筒录音 录制截屏视频保存沙盒（另类实现方法）
OC的代码截图只有UI部分，U3D截图只有3D部分。为了解决这个问题截屏时我们需要把这两张图片合成为一张全新的图片。这里再说一下用苹果私有API截图是可以同时将UI部分U3D部分保存为一张图片，不过有可能APPStore不能审核通过所以大家还是老老实实用合并的方法来做。
unity脚本,如图所示.添加

然后我们将这个Unity3D工程导出成IOS的项目 。Unity会生成对应的XCODE工程。我们写一个全新的ViewController覆盖在U3D生成的OPGL viewController之上，用于写UI高级控件，接着打开UnityAppController.mm文件。

YourViewController * myView = [[YourViewController alloc] init];
[UnityGetGLViewController().view addSubview:myView.view];
