Poco C++是一个强大的跨平台C++库，你可以在iPhone程序中使用它，如果：

你打算使你的程序跨平台。
你喜欢使用C++或希望使用Poco C++中的功能如：XML，Zip等。

目前，最新Poco C++版本为1.3.6P1，根据文档，它可以编译为iPhone静态库。但是我试用了一下，无法使用在iPhone Xcode项目中链接，不知何故。所以我自己创建了下列Xcode项目：

Poco Foundation
Poco Util
Poco Net
Poco XML
Poco Zip

另外，由于Crypto，Data，NetSSL_OpenSSL库需要外部库而且目前我不需要使用，所以没有包括。另外我增加了一个目录iPhoneSamples，它目前包括了一个示例程序HelloPoco，演示了怎样在iPhone项目中使用Poco C++库（此演示程序十分简单，它调用Poco中的UUID功能，产生一个UUID，显示与屏幕上）。下面是包括了此展示程序以及各Xcode文件的Poco包的下载：

Hi! Awesome work!
你好！很了不起的作品！

I’ve been trying to include the poco library in a iPhone XCode template for OpenFrameworks but I always get multiple errors.

我已经试着把POCO库文件合并进 iPhone XCODE 用来打开 OpenFrameworks 但是我总是碰到多重错误。

It’s possible to include POCO in a OpenFrameworks iPhone XCode project?
可能把POCO库文件合并进 iPhone XCODE 程序么？

Any answer will be highly appreciated.

任何回答我都会高兴。

Sorry, I haven’t tried it with OpenFrameworks. But theoretically it should be no problem at all.

Have you tried my Xcode project for POCO C++? What are the error messages you have when you’re compiling your code?

Hi! Thanks for the answer! I’m just a beginner in Xcode/C++ and maybe I don’t explain myself correctly. Sorry about that.

Yes, I checked your Xcode project for Poco C++ and it worked perfect with no errors.

As you said (I understood), there’s a problem linking the libraries binaries and you have to compile POCO as dependency to be included in a xcode project. Am I right?.

My problem is when I try to do that on an existing OpenFrameworks/Xcode project. I don’t know how to include POCO as depency in a Openframeworks Iphone project.

Thanks in advance for your time.

I see. The steps is :

1. Open your Xcode project.
2. Add existing files. Add Poco C++ library i.e. PocoFoundation projects and other projects, for example PocoXml projects.
3. Right click your project Target, and select “Get Info”, then add dependency.
4. Drag .a files for examples PocoFoundation.a and PocoXml.a into “Copy library files” under your project Target.
5. Add you Poco C++ header file paths to your “Search Path”.

If you still have problem, please send your sample project file to me and I’ll add Poco C++ dependency for you.
