在XCode中使用Pascal库(Using a Pascal Library in XCode)

 我正在开发一个iOS应用程序（OSX 10.7.4，XCode 4.3.3，目标iOS版本5.1）。 我已经构建了接口，但应用程序将使用的核心功能是用Pascal编写的。 我没有将Pascal函数移植到C（并且必须维护两个副本），而是在寻找一种方法来创建一个可以导入到XCode并由Objective-C代码调用的Pascal库。 
 
 Pascal函数只不过是计算（没有接口代码等）。 我希望它如何工作的一个例子就是：用户按下一个按钮，Objective-C代码收集输入的数据，调用相应的Pascal计算函数，然后返回并显示结果--Pascal仅用于提供结果。 
 
 我找到了FreePascal ，我假设这是我要开始的地方，但是我无法找到关于如何完成我想做的事情的任何明确信息。 我也发现了这个演练 ，但最终结果是你可以使用Pascal来实际编写你的应用程序 - 与我需要的东西相比，这似乎有些过分。 
 
 我的问题是：在我已经构建的iOS应用程序中使用我的核心Pascal函数的最简单方法是什么？ 是将FreePascal集成到XCode中并将我当前的应用程序故事板和代码导入绝对必要的Pascal模板之一，还是可以使用其他方法创建兼容的Pascal库并从我的代码中引用它？ 
 
 我非常感谢所提供的任何帮助（即使只是一个链接）。 我已经做了很多搜索，并且真的希望解决这个问题。 

I am developing an iOS app (OSX 10.7.4, XCode 4.3.3, and targeting iOS version 5.1). I have the interface already built, but the core functions the app will be using are written in Pascal. Rather than porting the Pascal functions to C (and having to maintain two copies), I was looking for a way to create a Pascal library that can be imported into XCode and called by the Objective-C code. 
 
The Pascal functions are nothing more than calculations (no interface code, etc.). An example of how I would like it to work would go something like: the user pushes a button, the Objective-C code collects the entered data, the appropriate Pascal calculating function is called, and then the result is returned and displayed--Pascal only being used to provide the result.
 
I found FreePascal, and am assuming that is where I would start, but I have not been able to find any clear information regarding how to accomplish what I want to do. I also found this walkthrough, but the end result is that you can use Pascal to actually write your applications--which seems like overkill compared to what I need.
 
My question is: what is the the easiest way to use my core Pascal functions within my already built iOS app? Is integrating FreePascal into XCode and importing my current application storyboard and code into one of the Pascal templates absolutely necessary, or is it possible to create a compatible Pascal library using another method and reference it from my code? 
 
I would very grateful for any help provided (even just a link). I've done a lot of searching, and would really like to get this problem solved.
