      class DJIWaypointMissionOperator

      @interface DJIWaypointMissionOperator : NSObject
      Header:DJIWaypointMissionOperator.h
      Inherits From:NSObject
      Description:

      The waypoint operator is the only object that controls, runs and monitors Waypoint Missions. It can be accessed from DJIMissionControl.

      Preparation

      Operator
      method
      loadMission
      method loadMission
      -(NSError * _Nullable)loadMission:(DJIWaypointMission *)mission
      Header:DJIWaypointMissionOperator.h
      Description:

      Loads a waypoint mission into the operator. A mission can be loaded only when the DJIWaypointMissionState is one of the following:

      Calling loadMission when the current state is DJIWaypointMissionStateReadyToExecute will change the state to DJIWaypointMissionStateReadyToUpload. After calling loadMission, latestExecutionProgress will be reset to nil.

      Input Parameters:
      DJIWaypointMission * missionWaypoint mission to load.
      Return:
      NSError * _NullableReturns an error when mission data is invalid or the mission cannot be loaded in the current state.
      property loadedMission
      @property (readonly, nonatomic, nullable) DJIWaypointMission *loadedMission
      Header:DJIWaypointMissionOperator.h
      Description:

      Gets the currently loaded mission of the operator. There are two ways to load a mission. 1. A mission can be loaded by user through loadMission. 2. If the aircraft is already executing a waypoint mission when SDK is re-connected, the operator will download part of the mission's information from the aircraft and load it automatically. In that case, the loaded mission will only contain the summary of the executing mission but information for each waypoint is absent. User can call downloadMissionWithCompletion to get all the information for the loaded mission. The loadedMission will be reset to nil when the execution of the loadedMission is stopped, finished or interrupted.

      Get Previous Interruption
      method
      getPreviousInterruptionWithCompletion
      method getPreviousInterruptionWithCompletion
      - (void)getPreviousInterruptionWithCompletion:(void(^)(DJIWaypointMissionInterruption *_Nullable interruption, NSError *_Nullable error))completion
      Header:DJIWaypointMissionOperator.h
      Description:

      Gets the interruption of the last waypoint mission. If a waypoint mission is interrupted before the completion, the aircraft will record the interruption information. This information is only available when the last waypoint mission is incomplete and the first waypoint of the mission has been reached. The interruption will also be recorded if the mission is stopped by the user. The interruption information is recorded in the aircraft and the information persists even after the aircraft's reboot.

      Input Parameters:
      DJIWaypointMissionInterruption *_Nullable interruptionThe interruption information to get. Returns NULL if there is any error.
      NSError *_Nullable errorError retrieving the value.
      void(^)(DJIWaypointMissionInterruption *_Nullable interruption, NSError *_Nullable error) completionCompletion block to receive the result.
      Mission Upload to Aircraft
      method
      uploadMissionWithCompletion
      method uploadMissionWithCompletion
      - (void)uploadMissionWithCompletion:(DJICompletionBlock)completion
      Header:DJIWaypointMissionOperator.h
      Description:

      Starts to upload the loadedMission to the aircraft. It can only be called when the loadedMission is complete and the currentState is DJIWaypointMissionStateReadyToUpload. If a timeout error occurs during the previous upload, the upload operation will resume from the previous break-point. After a mission is uploaded successfully, the DJIWaypointMissionState will become DJIWaypointMissionStateReadyToExecute.

      Input Parameters:
      DJICompletionBlock completionCompletion block that will be called when the upload operation succeeds or fails to start. If it is started successfully, use addListenerToUploadEvent:withQueue:andBlock to receive the detailed progress.
      Mission Download from Aircraft
      method
      downloadMissionWithCompletion
      method downloadMissionWithCompletion
      - (void)downloadMissionWithCompletion:(DJICompletionBlock)completion
      Header:DJIWaypointMissionOperator.h
      Description:

      Downloads information of each waypoint from aircraft and save it to loadedMission. If a download operation is started, the operator will download the information of waypoints missing in loadedMission one-by-one in ascending order. If loadedMission is already complete (containing all the waypoints), this method will call completion immediately without error. It can only be called when the currentState is one of the following: - DJIWaypointMissionStateExecuting - DJIWaypointMissionStateExecutionPaused

      Input Parameters:
      DJICompletionBlock completionCompletion block that will be called when the download operation succeeds or fails to start. If it is started successfully, use addListenerToDownloadEvent:withQueue:andBlock to receive the detailed progress.

      - (void)resumeMissionWithCompletion:(DJICompletionBlock)completion
      Header:DJIWaypointMissionOperator.h
      Description:

      Resumes the paused mission. It can only be called when the currentState is DJIWaypointMissionStateExecutionPaused. After a mission is resumed successfully, the currentState will become DJIWaypointMissionStateExecuting.

      Input Parameters:
      DJICompletionBlock completionCompletion block that will be called when the operator succeeds or fails to resume the mission. If it fails, an error will be returned.

      Description:

      Set the flight speed while the mission is executing automatically (without manual joystick speed input). This is the only property or method in this class that can communicate with the aircraft during a mission. All other properties and methods are used offline to prepare the mission which is then uploaded to the aircraft.

      Input Parameters:
      float speedAuto flight speed to be set. The absolute value of the auto flight speed should be less than or equal to the maxFlightSpeed. Its range is [-maxFlightSpeed, maxFlightSpeed] m/s.
