In general, the function of SCCaptureDeviceAuthorizationChecker is to speed up the checking of AVMediaTypeVideo
|
|
authorization. It would cache the authorization value. 'preloadVideoCaptureAuthorization' would be called very early
|
|
after the app is launched to populate the cached value. 'authorizedForVideoCapture' could be called to get the value
|
|
synchronously.
