如何检测iPad上启动画面动画的应用启动方向!

import UIKit
import CoreMotion

class ViewController: UIViewController {
    let motionManager = CMMotionManager()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 检测设备方向
        detectDeviceOrientation()
    }
    
    func detectDeviceOrientation() {
        if motionManager.isDeviceMotionAvailable {
            motionManager.deviceMotionUpdateInterval = 0.1
            motionManager.startDeviceMotionUpdates(to: OperationQueue.current!) { (data, error) in
                guard let data = data else {
                    return
                }
                
                let attitude = data.attitude
                
                // 获取设备的俯仰角、滚动角和偏航角
                let pitch = attitude.pitch
                let roll = attitude.roll
                let yaw = attitude.yaw
                
                // 根据设备的方向来调整应用启动画面的方向
                if pitch > -0.5 && pitch < 0.5 {
                    // 设备处于竖直方向
                    self.setStartupAnimationOrientation(.portrait)
                } else if roll > 0.5 {
                    // 设备处于向左横屏方向
                    self.setStartupAnimationOrientation(.landscapeLeft)
                } else if roll < -0.5 {
                    // 设备处于向右横屏方向
                    self.setStartupAnimationOrientation(.landscapeRight)
                } else if yaw > 0.5 {
                    // 设备处于倒置方向
                    self.setStartupAnimationOrientation(.portraitUpsideDown)
                }
            }
        }
    }
    
    func setStartupAnimationOrientation(_ orientation: UIInterfaceOrientation) {
        // 设置启动画面的方向
        UIView.setAnimationsEnabled(false)
        UIApplication.shared.setStatusBarOrientation(orientation, animated: false)
        UIView.setAnimationsEnabled(true)
    }
}
