ios - 如何使用CoreMotion框架确定设备位置？

Question

例如:应用程序运行时，我们初始化了起始坐标(x=0, y=0, z=0)并且坐标系在启动时等于设备坐标系，然后它必须被固定，即不连接到设备。我想在 MotionManager 事件触发时的每个时刻确定 x, y, z，如下所示:

motionManager.startDeviceMotionUpdates(to: OperationQueue.current!) { data, error in
    x = ...
    y = ...
    z = ...
}

但我不知道该怎么做。

提前致谢!

Answer 1

像这样使用它:

motionManger.startDeviceMotionUpdates(to: OperationQueue.current!) { (deviceMotion, deviceMotionError) in
            self.handleDeviceMotionUpdates(deviceMotion!)
}

func handleDeviceMotionUpdates(_ deviceMotion: CMDeviceMotion){

   let acceleration = deviceMotion.gravity
   print("Acceleration X>\(acceleration.x) Y>\(acceleration.y) Z>\(acceleration.z)\n")

   let userAcceleration = deviceMotion.userAcceleration
   print("User Acceleration X>\(userAcceleration.x) Y>\(userAcceleration.y) Z>\(userAcceleration.z)\n")
}
