Using Protocol Buffers with Objective-C
提问by Richard Stelling
Has anyone used Google's Protocol Bufferswhen developing applications in Objective-C?
有没有人在 Objective-C 中开发应用程序时使用过Google 的 Protocol Buffers？
Are there any current projects for compiling .protofiles into Objective-C, all the Google docs simply refer to Java, C++ or Python.
当前是否有任何将.proto文件编译为 Objective-C 的项目，所有的 Google 文档都只是指 Java、C++ 或 Python。

I've been working on an fork of Cyrus' project. It's based on protobuf 2.3 and works as a protocplugin (protoc-gen-objc) instead of requiring a modified protobuf distribution.
我一直在研究 Cyrus 项目的一个分支。它基于 protobuf 2.3 并作为protoc插件 ( protoc-gen-objc) 工作，而不需要修改 protobuf 发行版。
You can find it as the protobuf-objproject on GitHub.
你可以在 GitHub 上找到它作为protobuf-obj项目。

The Third Partypage lists this Objective-C port. Unfortunately the project appears to be empty at the moment, but it's encouraging to see it anyway. I had heard internal rumours of the project, but hadn't seen it as an open source project before today.
该第三方网页列出了这个Objective-C的端口。不幸的是，该项目目前似乎是空的，但无论如何看到它还是令人鼓舞的。我听说过这个项目的内部传闻，但在今天之前并没有将它视为一个开源项目。
You could get in touch with the project owner (Cyrus Najmabadi) to ask about it though...
您可以与项目所有者 (Cyrus Najmabadi) 取得联系，询问有关它的问题...
(Small piece of trivia - Cyrus used to work on the C# team in Microsoft before he joined Google.)
（小知识 - Cyrus 在加入 Google 之前曾在 Microsoft 的 C# 团队工作。）

This may or may not be helpful, but Apache Thrift(originally developed at Facebook) supports Cocoa, and seems to have people attempting to use it in the iPhone.
这可能有帮助，也可能没有帮助，但Apache Thrift（最初由 Facebook 开发）支持 Cocoa，并且似乎有人试图在 iPhone 中使用它。
Thrift officially supports more languages. But Protocol Buffers have 5x the Stack Overflow interest, so who knows if it's a good replacement in terms of maintenance—not to mention compatibility with your own project! Still, maybe it's worth consideration.
Thrift 正式支持更多语言。但是 Protocol Buffers 对 Stack Overflow 的兴趣是 Stack Overflow 的 5 倍，所以谁知道它在维护方面是否是一个很好的替代品——更不用说与您自己的项目的兼容性了！不过，也许值得考虑。
I just asked a related question you may find helpful if it gets good answers: Any success using Apache Thrift on iPhone?
我刚刚问了一个相关问题，如果得到好的答案，您可能会觉得有帮助：在 iPhone 上使用 Apache Thrift 是否成功？

To generate Objective-C code from a .protofile call the compiler with the objc_outoption:
要从文件中生成 Objective-C 代码，.proto请使用以下objc_out选项调用编译器：
protoc --proto_path=src --objc_out=build/gen src/foo.proto src/bar/baz.proto
