Application.RequestUserAuthorization

Description

Request authorization to use the webcam or microphone on iOS.

The call of Application.RequestUserAuthorization requests permission for microphone and camera. The application shows a dialog box to the user and waits for operation to complete before being able to use these features.

Note: Use Application.HasUserAuthorization to query the result of the operation.

function Start() {
    // Request permission to use both webcam and microphone.
    yield Application.RequestUserAuthorization (UserAuthorization.WebCam | UserAuthorization.Microphone);

    if (Application.HasUserAuthorization(UserAuthorization.WebCam | UserAuthorization.Microphone))
    {
        // we got permission. Set up webcam and microphone here.
    }
    else
    {
        // no permission. Show error here.
    }
}

// Show WebCams and Microphones on an iPhone/iPad.
// Make sure NSCameraUsageDescription and NSMicrophoneUsageDescription
