在执行本机代码xamarin.ios时获得了SIGABRT

Question

我已经构建了一个xamarin.ios应用程序.该应用程序一直工作得很好.没有代码更改,并且突然出现,应用程序现在在访问摄像头时崩溃.我不知道为什么会这样,有人能解释一下这个问题吗？我已经谷歌围绕这个错误并尝试了各种各样的东西,包括删除各种包.我最近更新到ios 10,但更新后应用程序仍然正常工作.错误如下:

这是因为您的iOS 10更新.您需要立即申请相机的许可.以下博客文章现在解释了如何设置这些权限.

https://blog.xamarin.com/new-ios-10-privacy-permission-settings/

从iOS 10开始,几乎所有需要请求授权的API和其他API(如打开相机或照片库)都需要一个新的键值对来描述它们在Info.plist中的用法.这与在使用Geolocation和iBeacon API时将NSLocationWhenInUseUsageDescription或NSLocationAlwaysUsageDescription放入Info.plit的要求非常相似.现在的区别是,当应用程序尝试授权而没有设置这些密钥时,应用程序将崩溃.
