This class defines an actuator for DJIWaypointV2Action. It determines how the action is performed when a waypoint mission is executed. You can add multiple actions with uploadWaypointActions:withCompletion. There are two scenarios for it. Parallel execution: In parallel scenario, You can excute multiple actions with one trigger at the same time, the actions must be sent to different modules. For example, since gimbal and camera are different modules, you can use a trigger to rotate gimbal pitch and you can also use another triger with identical parameters as the previous triger to take photos in order to execute these two actions at the same time. You can not use two triggers with identical parameters to take photos and record videos at the same time, because these two actions are excuted with the same mudule. Serial execution: In serial scenario, You can excute multiple actions one by one. For example, if you want to add actions for camera to take photo and record video, you should add action with DJIWaypointV2AssociateTriggerParam. and set the associated action ID with previous action, the actionAssociatedType should be DJIWaypointV2TriggerAssociatedTimingTypeAfterFinished.
