Method Detail

userActivityDidReceiveInputStreamOutputStream

default void userActivityDidReceiveInputStreamOutputStream(NSUserActivity userActivity,
                                                           NSInputStream inputStream,

If supportsContinuationStreams is set to YES the continuing side can request streams back to this user activity. This delegate callback will be received with the incoming streams from the other side. The streams will be in an unopened state. The streams should be opened immediately to start receiving requests from the continuing side.

default void userActivityWasContinued(NSUserActivity userActivity)

The user activity was continued on another device.

userActivityWillSave

default void userActivityWillSave(NSUserActivity userActivity)

The user activity will be saved (to be continued or persisted). The receiver should update the activity with current activity state.
