xamarin - 部署到 iPhone 时如何在 Xamarin IOS 中禁用 AOT

Question

我的解决方案包含 3 个项目:

1. 我的后端项目与程序集 My_Test_App(可移植)

2. My_Test_App.Android

3. My_Test_App.iOS

我使用VS2015开发，使用mac构建部署。它在 iOS 模拟器中运行良好。我的 iOS 项目不使用链接器。我还没有选中 LLVM 和增量构建。

但是当我尝试调试 iPhone 设备时，出现了这个错误:

Severity    Code    Description Project File    Line    Suppression State
Error       Could not AOT the assembly/Users/myMacName/Library/Caches/Xamarin/mtbs/builds/My_Test_App.iOS/c7eaf4168fcb1f8aaecd3a6cbb0f37ee/obj/iPhone/Release/mtouch-cache/64/Build/My_Test_App.dll'    My_Test_App.iOS 

我的问题是:

1. 如何在 Xamarin.iOS 项目中禁用 AOT？查看iOS项目的csproj文件，droid项目中没有like。

2. 禁用 AOT 是解决问题的正确方法吗？

感谢您的回答!

Answer 1

1. 您不能在 iOS 上禁用 AOT，您的项目将无法运行，因为 iDevices 不允许 JIT'ing
2. 很遗憾没有。

我们需要更长的构建日志(添加“-v -v -v”作为“mtouch”参数)，但它可能会发生，因为程序集太大。您可能希望在 iOS 项目设置中启用链接所有程序集。
