Mono + Xcode:如何使用Xamarin Studio在C#中编写一个库，并在Xcode的CocoaTouch项目中使用它? [英] Mono + Xcode: How to author a library in C# using Xamarin Studio, and consume it in a CocoaTouch project within Xcode?

问题描述

对于最终将移植到Android/Winphone的iOS应用，我希望能够用c#编写一些可重用的库，但是希望使用传统的Obj-C编写iOS UI并引用用c#编写的库从Xcode中提取并从Obj-C中使用.

For an iOS app that will eventually be ported to Android/Winphone, I would love to be able to write some re-usable libraries in c#, but author the iOS UI in traditional Obj-C and reference the library written in c# from Xcode and consume it from Obj-C.

我发现很多文档都在谈论通过绑定的另一种方式(Obj-C-> C#)，但是与我的问题无关.另外，在4年前在这里提出了类似的问题，但是生态系统发生了很多变化，信息似乎已过时，答案中的某些链接现在重定向到其他地方:

I've found lots of docs that talk about going the other way via bindings (Obj-C -> C#), but not much pertaining to my question. Also, a similar question was asked 4 years ago here, but a lot has changed in the ecosystem, the info seems out of date, and some of the links in the answers now redirect elsewhere:

• 有没有办法混合MonoTouch和Objective -C?

那么，这可能吗?如果是这样，那么如何?今天实现它的最佳方法是什么? (或者，这是一个坏主意，应该放弃吗?)

So, is this possible? If so how, and what's the best way to achieve it today? (Or alternately, is this a bad idea and should be abandoned?)

推荐答案

否，当前无法从Objective-C使用C#库.

No, it is not currently possible to consume a C# library from Objective-C.

请注意，通常可以通过一些独创性的方法来完成此操作-唯一的实际要求是该应用程序必须是Xamarin.iOS应用程序，而入口点必须是托管的Main方法.在您的Main方法中，您可以调用本机(C/Objective-C)代码，并在其中拥有所有逻辑.

Note that it is usually possible to do it the other way with some ingenuity - the only real requirement is that the app must be a Xamarin.iOS app and the entry point the managed Main method. In your Main method you can call into native (C/Objective-C) code and have all your logic there.
