I am trying to use the PHPhotoLibrary class in an iOS project, but need it in one of my mixed code Objective-C/C++ files. I am getting a build error bc apparently the needed import is not correct. The Apple docs here clearly show that @import Photos is to be used, so in my Build Settings I turned on "Enable Modules (C and Objective-C)" and added @import Photos with my other imports. That however did not fix Xcode's objection to my using @import Photos. The problem is as one of the posts for this SO question here explains, you can only use the @import Photos style of include in .mm files.
我正在尝试在一个iOS项目中使用PHPhotoLibrary类，但是在我的混合代码Objective-C/ c++文件中需要它。我得到了一个构建错误bc，显然所需的导入是不正确的。这里的Apple docs清楚地显示了将要使用的@import Photos，所以在我的构建设置中，我打开了“启用模块(C和Objective-C)”，并在我的其他导入中添加了@import Photos。然而，这并没有解决Xcode反对我使用@import Photos的问题。问题在于，作为本文的一篇文章，这里的问题解释说，您只能使用.mm文件中包含的@import Photos样式。
(I'm not using Swift, only Objective-C and in a few files mixed Objective-C and C++)
(我不使用Swift，只使用Objective-C，在一些混合Objective-C和c++的文件中)
How then can I properly import/include in my .mm file so my PHPhotoLibrary code will build?
那么，如何正确地导入/包含我的.mm文件，从而构建我的PHPhotoLibrary代码呢?
