问题
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.
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 Also, a similar question was asked 4 years ago here, but a lot has changed in the ecosystem, the info seems out of date, and some of the links in the answers now redirect elsewhere:
- Is there a way to mix MonoTouch and Objective-C?
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?)
回答1:
No, it is not currently possible to consume a C# library from Objective-C.
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.
