Disable Add Call option from CallKit

问题:

Is there a way to disable Add Call option from Callkit when receiving a VoIP call?

I couldn't find any api to disable this. But WhatsApp disabled this feature.

回答1:

Set the supportsGrouping, supportsUngrouping and supportsHolding properties to false in the CXCallUpdate for the call.

You need to set both supportsGrouping, supportsUngrouping and supportsHolding properties to false in the CXCallUpdate, and set maximumCallGroups and maximumCallsPerCallGroup to 1 in your CXProviderConfiguration.
