如何获取iPhone视图的当前方向或设备的最后方向？

import CoreMotion

let motionManager = CMMotionManager()

if motionManager.isDeviceMotionAvailable {
    motionManager.deviceMotionUpdateInterval = 0.1
    motionManager.startDeviceMotionUpdates(to: OperationQueue.main) { (motion, error) in
        guard let motion = motion else {
            // 处理错误
            return
        }
        
        let attitude = motion.attitude
        let pitch = attitude.pitch
        let roll = attitude.roll
        let yaw = attitude.yaw
        
        // 根据需要处理设备的方向
        
        // 停止陀螺仪更新
        motionManager.stopDeviceMotionUpdates()
    }
}

let currentOrientation = UIApplication.shared.statusBarOrientation
