如何保持 iwatch 应用程序处于活动状态以传输运动和健康数据

Question

我正在开发一个需要加速度计、陀螺仪和计步器数据以及心率的应用程序。我正在将此数据从 iwatch 传输到 iPhone，然后从 iPhone 我需要通过 MQTT 协议同步此数据。现在我的问题是，一旦 iwatch 窗口禁用，我的应用程序就会终止。我正在使用核心运动和现场锻炼课程。 任何人都可以帮助我如何保持 iwatch 应用程序处于活动状态或从非活动模式传输上述数据？

1. 设置HKWorkoutSession和CoreMotion监听器

   import WatchKit
   import Foundation
   import CoreMotion
   import HealthKit
   
   enum VelocityVector: Int {
       case x, y, z
   }
   
   class InterfaceController: WKInterfaceController {
   
       @IBOutlet weak var labelVelocity: WKInterfaceLabel!
       let coreMotion = CMMotionManager.init()
       let pool = OperationQueue.init()
       let currentSession: HKWorkoutSession?
       let healthKit = HKHealthStore()
       
       override func awake(withContext context: Any?) {
           coreMotion.accelerometerUpdateInterval = 0.1
           coreMotion.startAccelerometerUpdates(to: pool) { data, err in
               guard let _data = data else { return }
               DispatchQueue.main.async {
                   self.labelVelocity.setText(String.init(format: "G-Force (x:y:z) %.3f:%.3f:%.3f", arguments: [_data.acceleration.x, _data.acceleration.y, _data.acceleration.z]))
               }
           }
           
           let config = HKWorkoutConfiguration.init()
           config.activityType = .other
           config.locationType = .unknown
           
           do {
               self.currentSession = try HKWorkoutSession.init(healthStore: self.healthKit, configuration: config)
               self.currentSession?.startActivity(with: Date())
           } catch error {
               print(error?.localizedDescription)
           }        
       }
   
       private func stopHKWorkoutSession() {
           self.currentSession?.stopActivity(with: Date())
           self.currentSession?.end()
       }
       
       override func willActivate() {
           // This method is called when watch view controller is about to be visible to user
       }
       
       override func didDeactivate() {
           // This method is called when watch view controller is no longer visible
       }
   
   }
   

   2. 在后台模式下启用“锻炼处理”：

是否可以直接从手表将 heartkit 数据发送到服务器，而无需伴侣（iphone）......？
