C ++从SpeakHere在iPhone应用程序 [英] C++ from SpeakHere in iPhone app

问题描述

我制作了一个模板应用程序，在那里我抓住了SpeakHere示例的记录部分，并删除了文件处理部分，但我努力让C ++部分的应用程序工作正常。一旦它进入C ++类，它会得到语法错误。如果我不导入头文件从C ++（当然不使用代码）到我的Objective C类，一切正常。我看不出我之间的区别，我的例子是做它。你能看到差别吗？

I've made a template app where I've grabbed the recording part of the SpeakHere example and removed the file handling part, but I'm struggeling to get the C++ part of the app working right. As soon as it enters the C++ class, it gets syntax errors. If I don't import the header files from C++ (and then of course don't use the code) into my Objective C classes, all works fine. I cannot see the difference between how I'm doing it and the example is doing it. Can you see the difference?

有什么想法吗？

推荐答案

头文件变成纯Objective-C代码（ .m ） - 这将无法工作，你必须使用 Objective-C ++ （ .mm ）或封装C ++使用不透明指针的Objective-C类中的类。

You are indirectly including the C++ headers into plain Objective-C code (.m) - that won't work, you have to use Objective-C++ (.mm) all the way or encapsulate the C++ classes in Objective-C classes using opaque pointers.

一个有问题的链：

• 类/ MainViewController.m ，纯Objective-


• RecorderLink.h 包括


• AQRecorder.h ，这是C ++

• Classes/MainViewController.m, plain Objective-C, includes
• RecorderLink.h, includes
• AQRecorder.h, which is C++
