AVPlayerItemMBS.requestContentAuthorizationAsynchronously(timeoutInterval as Double, tag as Variant = nil)

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	❌ No	Desktop, Console & Web

Causes appropriate action to be taken to allow the user to authorize the content for playback.

timeoutInterval: The maximum amount of time in seconds to wait for the user to authorize the content before calling the handler block with a timeout result.

Calling this method will present the user with the opportunity to authorize the content (for example, by launching iTunes and prompting the user to enter their Apple ID and password).

When the user has taken action (or the timeout has elapsed), the AVFoundationMBS.requestContentAuthorizationCompleted event is invoked. You determine the status of the authorization attempt by checking the value of the contentAuthorizationRequestStatus property.

Even if the status indicates a completed authorization, the content may still not be authorized (for example, if the user authorizes an Apple ID other than that associated with the content). You should re-check the value of contentAuthorizationRequestStatus to verify whether the content has actually been authorized before continuing. It is not necessary to call this method if the value of contentAuthorizationRequestStatus is already true.

With tag you can pass any value you like to the event later. This can be for example an object reference or a number in an array. Be aware that the reference to this tag value is kept until the event is called and can cause memory reference cycles.
