Utilizing C++ in iOS and Mac OS X applications
提问by Kris
I'm somewhat moderate in my C++ knowledge but know next to nothing regarding Objective-C. I am planning (and even starting to) learn Objective-C so I can attempt to write a few iOS and even Mac OS X applications but I'm very curious about something I haven't been able to find yet.
我的 C++ 知识有点中庸，但对 Objective-C 几乎一无所知。我正在计划（甚至开始）学习 Objective-C，这样我就可以尝试编写一些 iOS 甚至 Mac OS X 应用程序，但我对尚未找到的东西很好奇。
Is it possible to write an iOS and / or a Mac OS X application entirely with C++ including the UI components? If it isn't possible to do it entirely in C++ then to what degree is it possible to use mostly C++?
是否可以完全使用 C++ 编写 iOS 和/或 Mac OS X 应用程序，包括 UI 组件？如果不可能完全用 C++ 来完成，那么主要使用 C++ 的程度有多大？
I haven't seen any examples that demonstrate either of these items. I am planning on writing a few mobile applications for iOS and Android and, where possible, I'd like to contain most of my logic inside of C++ code for maximum portability. I already know I can do this but I am unsure of the degree.
我还没有看到任何演示这些项目的示例。我计划为 iOS 和 Android 编写一些移动应用程序，并且在可能的情况下，我希望将我的大部分逻辑包含在 C++ 代码中，以实现最大的可移植性。我已经知道我可以做到这一点，但我不确定学位。

Short answer, yes.
简短的回答，是的。
For pure C++, you should take a look at the QT framework.
Otherwise, you'll have hard time for the UI part.
对于纯 C++，你应该看看QT 框架。
否则，您将很难处理 UI 部分。
But also remember that Objective-C can be mixed with C++.
That's called Objective-C++(.mm files).
但也要记住，Objective-C 可以与 C++ 混合使用。
这就是所谓的Objective-C++（.mm 文件）。
You can then write code that mix C++ and Objective-C code. With this, you can have the UI parts in Objective-C (may be better, as it will use the native frameworks for the UI components), and the other things in C++.
然后，您可以编写混合 C++ 和 Objective-C 代码的代码。有了这个，你可以在 Objective-C 中拥有 UI 部分（可能更好，因为它将使用 UI 组件的本机框架），而在 C++ 中拥有其他东西。
If you've decided to learn Objective-C, but still want to code in C++ for some parts, I would recommend this approach, instead of pure C++.
如果您决定学习 Objective-C，但仍想用 C++ 编写某些部分的代码，我会推荐这种方法，而不是纯 C++。
On iOS, this is also the only way. While you can code in C++, you have to use Objective-C for the UI part.
在iOS 上，这也是唯一的方法。虽然您可以使用 C++ 进行编码，但您必须将 Objective-C 用于 UI 部分。

I don't know about Mac OS, but in IOS applications you can use C++ in logic but you have to write user interface on Objective-C.
我不了解 Mac OS，但在 IOS 应用程序中，您可以在逻辑中使用 C++，但您必须在 Objective-C 上编写用户界面。

I think it is possible to use pure c++ if you want to depend on some 3rd part lib, then yes.
我认为如果您想依赖某些第三部分库，可以使用纯 C++，然后可以。
Without that 3rd part lib you have to write all the UI using objective-c the rest you can use c++ as much as you like.
如果没有第三部分库，您必须使用objective-c 编写所有UI，其余的您可以随心所欲地使用c++。

You could use Cocos2d-x engine and write pure C++ for your iOS app, including UI (cocos has basic ui classes like buttons, scroll views, table views, etc - but you need to develop your own Controllers, and Models using various C++ libraries like Hiberlite, or raw SQLite etc)
您可以使用 Cocos2d-x 引擎并为您的 iOS 应用程序编写纯 C++，包括 UI（cocos 具有基本的 ui 类，如按钮、滚动视图、表格视图等 - 但您需要使用各种 C++ 库开发自己的控制器和模型如 Hiberlite 或原始 SQLite 等）
Cocos has its own interface with iOS/MacOS (a few basic .mm objective-c classes to setup Application run cycle - like app delegate, or runloop and drawing cycle)
Cocos 有自己的 iOS/MacOS 接口（一些基本的 .mm 目标 c 类来设置应用程序运行周期 - 如应用程序委托，或运行循环和绘图周期）
So you just write your user code with C++
所以你只需用 C++ 编写你的用户代码
