执行本机代码时收到 SIGABRT xamarin.ios
Got a SIGABRT while executing native code xamarin.ios
我构建了一个 xamarin.ios 应用程序。该应用程序一直运行良好。没有代码更改，而且出乎意料的是，应用程序现在在访问相机时崩溃了。我不知道为什么会这样，任何人都可以阐明这个问题吗？我已经 google 解决了这个错误并尝试了各种方法，包括删除各种包。我最近更新到 ios 10，但应用程序在更新后仍然运行良好。错误如下：

application.
这是因为您的 iOS 10 更新。您现在需要请求相机的权限。下面的博客 post 解释了如何设置这些权限，现在。
https://devblogs.microsoft.com/xamarin/new-ios-10-privacy-permission-settings/
Starting in iOS 10, nearly all APIs that require requesting authorization and other APIs, such as opening the camera or photo gallery, require a new key value pair to describe their usage in the Info.plist. This is very similar to the requirement for NSLocationWhenInUseUsageDescription or NSLocationAlwaysUsageDescription to be put into the Info.plit when using Geolocation and iBeacon APIs. The difference now is that the application will crash when the app attempts authorization without these keys set.
