使用 Firebreath 框架将 cocoa 应用程序转换为 NPAPI 插件

我最近发现 Apple 在上一个版本的 Lion 和 Safari 中将不支持 webkit 模型，并且每个人都在迁移到 Firebreath 项目以使用 NPAPI。

我有一个基本的 Cocoa 应用程序，它与以下本机框架链接：

CoreGraphics
CoreData
IOKit
PFEventTaps （这是一个 3 方框架：Pfiddlesoft.com）

我从未使用过插件，所以这对我来说有点新，我从MAC 教程由 Richard bateman 编写，在遵循指导原则后，我最终为我的个人项目提供了一个 firebreath 项目模板。我所做的下一步只是将所有 Objective-C 类放入源文件文件夹中，添加与 4 个框架的链接，最后我将需要在插件中公开的新公共方法添加到 MyProjectPluinApi.h 例如（ registerMethod("MyMethod", make_method(this, &WilmerPlugInAPI::MyMethod ));

当我构建 firebreath 项目时，我收到很多编译错误，其中之一非常重复是： NSString 未在此范围内声明。 错误指向 NSObjCRuntime.h

到目前为止，我无法使用 XCODE 3.2.6 成功构建此版本，

这里出了什么问题？我需要改变我的所有代码来完成这个模板项目中的CPP风格吗？或者我可以以某种方式链接我的框架？有一些样本我可以看看吗？

更多详细信息：2011 年 11 月 7 日：我试图用一个简单的项目进行测试：

首先我创建项目 testOfFB
- 它在 /users/Me/Firebreath-dev/build/projects/testofFB 中生成
，然后我修改类 testFBApi.cpp 并将其重命名为 testFBApi.mm。
我编写了一个名为 testMath.m 的 Objective-c 类，并将其重命名为 testMath.mm
我添加了一个带有签名的方法 Add：
```
-(long) 添加:(long)a:(long)b:(long)c;
```

最后我用以下内容修改了文件 testFBApi.mm：

registerMethod("add", make_method(this, &testFBAPI::add ));

在 add 方法的实现中，我创建了 Objective-C 类方法“add”的实例来测试对我的 Objective-的调用 - c 方法。我做了包含并以这种方式更改了文件 /Mac/projectDef.cmake：
```
target_link_libraries(${PROJECT_NAME}
    ${PLUGIN_INTERNAL_DEPS}
    ${Cocoa.framework} // 添加的行
    ${Foundation.framework} //添加的行
）
```

我运行 prepmac.sh 脚本，然后构建 xcode 解决方案，出现相同的错误，而且还没有声明其他一些错误，例如 testFBApi 。

原文

I found recently that webkit model will be unsupported by Apple in Lion and Safari last release and that everybody is migrating to Firebreath project in order to use NPAPI.

I have a basic Cocoa Application which links with the following native frameworks:

CoreGraphics
CoreData
IOKit
PFEventTaps ( this is a 3 party framework by: Pfiddlesoft.com)

I've never used PlugIns so this is a little new for me, I started with the MAC tutorial written by Richard bateman and after following the guidelines I ends up with a firebreath project template for my personal project. the next step I made was just puting all my Objective-C classes into the Source Files folder adding the linking with the 4 frameworks, finally I added the new public methods I need to expose in the plug-In into the MyProjectPluinApi.h e.g.( registerMethod("MyMethod", make_method(this, &WilmerPlugInAPI::MyMethod ));

When I build the firebreath project I get a lot of compile errors, one of them very repetitive is:
NSString was not declared in this scope. The error points to NSObjCRuntime.h

Until now I can't get this build succesfully with XCODE 3.2.6

what is wrong here? I need to change all my code to accomplish the CPP style in this template project? Or I can link my frameworks in some way?
Is there some sample I can see?

MORE DETAILS: Nov 7 2011:
I was trying to test with a simple project:

First I create the project testOfFB
- it is generated in /users/Me/Firebreath-dev/build/projects/testofFB
then I modify the class testFBApi.cpp and rename it to testFBApi.mm.
I wrote an Objective-c class named testMath.m and rename it to testMath.mm
I add a method Add with the signature:
```
-(long) Add:(long)a:(long)b:(long)c;
```

Finally I modify the file testFBApi.mm with this:

registerMethod("add", make_method(this, &testFBAPI::add ));

In the implementation of add method I create an instance of the objective-c class method "add" to test the calling to my objective-c method. I did the includes and I changed the file /Mac/projectDef.cmake in this way:
```
target_link_libraries(${PROJECT_NAME}
    ${PLUGIN_INTERNAL_DEPS}
    ${Cocoa.framework} // added line
    ${Foundation.framework} //added line
)
```

I run the prepmac.sh script and then build the xcode solution and same errors appear plus some others like testFBApi has not been declared.
