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

问题 I created a Xamarin iOS binding project that requires the following frameworks: SystemConfiguration.framework CoreTelephony.framework libz.dylib libsqlite3.dylib I added the following line in my iOS binding project to the linkwith.cs file: Frameworks = "SystemConfiguration CoreTelephony" This seems to work correctly and tell that project to include these frameworks when binding.

问题 I've developed a cross platform for iOS and android using Xamarin Forms. My app uses several screens and some tjird party dependencies such as Facebook, google maps and firebase. Everything works good until I went to compile it in release mode. Assuming I want to support both armv7 and arm64, these are the app size: * without linking and optimization: 103mb. * with full optimization (link all + LLVM): 73mv. With the optimization and without armv7 I'm getting 40mb - that's my desired result

问题 I'm struggling adding the Facebook Android package (tried both with Nuget and component manager) to the Droid solution on my Xamarin.Forms project. It seems there's some kind of incompatibility between the package Xamarin.Forms and its dependencies and Facebook SDK package dependencies.

They work correctly and so does the navigation. I added another page and linked them up the same way as the first two and it does not work. I click the button to navigate to the view and nothing happens. I wire up both of the views like such btnPurchase.Clicked += (s, e) => this.Navigation.PushAsync(new PurchasePage()); btnContactUs.Clicked +
