在ipad中，我写入下列代码

我通过横屏进入时，打印下列值：

{

1. SDKVersion:"2.6.4"

2. albumAuthorized:true

3. batteryLevel:43

4. bluetoothEnabled:false

5. brand:"iPhone"

6. cameraAuthorized:true

7. deviceOrientation:"landscape"

8. errMsg:"getSystemInfo:ok"

9. fontSizeSetting:17

10. language:"zh_CN"

11. locationAuthorized:true

12. locationEnabled:true

13. microphoneAuthorized:true

14. model:"iPad Air 2 (WiFi)<iPad5,3>"

15. notificationAlertAuthorized:true

16. notificationAuthorized:true

17. notificationBadgeAuthorized:true

18. notificationSoundAuthorized:true

19. pixelRatio:2

20. platform:"ios"

21. screenHeight:768

22. screenWidth:1024

23. statusBarHeight:20

24. system:"iOS 12.1.4"

25. version:"7.0.3"

26. wifiEnabled:true

27. windowHeight:698

28. windowWidth:1024

}

然后我隐藏，通过竖屏进入时，返回的对象完全相同，也就是说`windowHeight`和`windowWidth`在屏幕方向改变时并不会变化，`deviceOrientation`也是，似乎这些信息在载入小程序后就完全固定了
