在 Xamarin 中读取 iOS 的相机权限 [英] Read camera permission for iOS in Xamarin

问题描述

我有一个用 Xamarin 开发的 iOS 应用.当应用程序没有访问麦克风的权限时，如果用户尝试从应用程序访问麦克风，我会使用 AVAudioSession.SharedInstance().RequestRecordPermission (delegate(bool grant)) 检查设置并显示一条消息.

I have an iOS app developed in Xamarin. When the app does not have permission to access the microphone, if the user tries to access the microphone from the app, I check the settings using AVAudioSession.SharedInstance().RequestRecordPermission (delegate(bool granted)) and display a message.

如果应用程序没有访问相机的权限，我现在需要做同样的事情.我需要检查相机是否获得许可并相应地显示一条消息.我该怎么做?

Now I need to do the same if the app does not have permission to access the camera. I need to check if permission is granted for camera and display a message accordingly. How can I do this?
