如何从 Objective-C 调用 PyObjC 代码？
可能的重复：
从 Objective-C 调用 Python
我是一名长期的 Python 程序员，但短期内时间可可程序员。我刚刚开始使用 PyObjC，完成工作是多么容易，真是令人惊奇。也就是说，我想尝试使用纯 ObjC 作为带有 PyObjC 模型的控制器。我可能会喜欢让 Python 成为 Python，让 Objective-C 成为 Objective-C。无论如何，我认为值得一试。
除了我无法弄清楚或找到任何关于如何从 Objective-C 调用 Python 的信息，只有相反的方式。有人可以向我指出这方面的任何资源吗？ （也许它在 PyObjC 网站上，但我只是不知道我在寻找什么？）
编辑：在基本层面上，我最感兴趣的是能够调用 Python 模块并获取一些本机 ObjC 数据类型后退。

Calling Python from Objective-C
I'm a long-time Python programmer and short-time Cocoa programmer. I'm just getting started with PyObjC and it's really amazing how easy it it is to get stuff done. That said, I wanted to try using pure ObjC for my controller with PyObjC models. I might be enjoy letting Python be Python and Objective-C be Objective-C. I figured it was worth a try, anyways.
Except I can't figure out or find anything about how to call Python from Objective-C, only the other way around. Can someone point me to any resources on this? (Maybe it's on the PyObjC site but I just don't know what I'm looking for?)
Edit: I'm most interested, at the basic level, in being able to call a Python module and get some native ObjC data types back.

有几种可能的方法。最诱人的是使用 py2app 从 Python 代码编译一个可加载包，您可以使用 NSBundle 访问主体类。不幸的是，这个用例并没有得到 py2app 开发人员的太多喜爱，而且我在 10.5 和 10.6 中发现了几个错误，包括将数据从 python 传回 Objective-C 时出现相当严重的内存泄漏。我不建议此时使用 py2app 。
第二种方法是反转嵌入。编写一个 Python cocoa 应用程序并在启动时从包中加载 Objective-C 代码（甚至在 main() 中）。如果您已经有一个大型 Objective-C 应用程序，这可能需要一些工作。据我所知，唯一的缺点是您无法在 Objective-C 代码中使用 GC，但这确实是使用 PyObjC 的普遍限制。
最后，您可以在 Objective-C 代码中实例化 python 解释器来加载 python 代码。这显然涉及更多，但如果您已经有一个大型 Objective-C 代码库并且想要向其中注入 Python 代码，这可能是最好的选择。 Xcode 中 Python-Cococa 应用程序模板中的 main.m 文件是开始查看此操作的好地方。
There are several possible approaches. The most tempting is to use py2app to compile a loadable bundle from your python code from which you can access the principal class using
NSBundle. Unfortunately, this use case hasn't gotten much love from the py2app developers, and I've found several bugs in 10.5 and 10.6, including a rather nasty memory leak when passing data from python back in to Objective-C. I wouldn't recommend using py2app at thist point.The second approach is invert the embedding. Write a Python cocoa app and load your Objective-C code from a bundle at startup (even in main()). If you already have a large Objective-C app, this may take a bit of work. The only downside, that I'm ware of, is that you won't be able to use GC in your Objective-C code, but this is really a universal limitation in working with PyObjC.
Finally, you can instantiate a python interpreter in your Objective-C code to load your python code. This is obviously more involved, but may the best option if you already have a large Objective-C codebase into which you want to inject your python code. The main.m file from the Python-Cococa application template in Xcode is a good place to start to see this in action.
