在这篇文章的基础上进行适配：

1.异形屏适配

通过PackageManager搜索并安装Device Simulator(需要unity版本2019.3以上)

通过菜单栏Window/General/Device Simulator打开

Game视图：

iPhoneX：

解决思路：

调整界面根节点的anchor，使其处于安全区域内

 1 using UnityEngine;
 2 
 3 [DisallowMultipleComponent]
 4 [RequireComponent(typeof(RectTransform))]
 5 public class SafeAreaRect : MonoBehaviour
 6 {
 7     private RectTransform rectTransform;
 8     private ScreenOrientation lastScreenOrientation;
 9 
10     private void Awake()
11     {
12         rectTransform = GetComponent<RectTransform>();
13         lastScreenOrientation = Screen.orientation;
14         ChangeRect();
15     }
16 
17     void Update()
18     {
19         if (lastScreenOrientation != Screen.orientation)
20         {
21             lastScreenOrientation = Screen.orientation;
22             ChangeRect();
23         }
24         //print(Screen.safeArea);
25         //print(Screen.orientation);
26         //print(Application.isMobilePlatform);
27         //print(Screen.width + "_" + Screen.height);
28     }
29 
30     private void ChangeRect()
31     {
32         ScreenOrientation screenOrientation = Screen.orientation;
33         Rect safeArea = Screen.safeArea;
34         if (screenOrientation == ScreenOrientation.Portrait || screenOrientation == ScreenOrientation.PortraitUpsideDown) //竖屏
35         {
36             rectTransform.anchorMin = new Vector2(safeArea.x / Screen.width, safeArea.y / Screen.height);
37             rectTransform.anchorMax = new Vector2((safeArea.x + safeArea.width) / Screen.width, (safeArea.y + safeArea.height) / Screen.height);
38         }
39         else //横屏
40         {
41             rectTransform.anchorMin = new Vector2(safeArea.x / Screen.width, safeArea.y / Screen.height);
42             rectTransform.anchorMax = new Vector2((safeArea.x + safeArea.width) / Screen.width, (safeArea.y + safeArea.height) / Screen.height);
43         }
44     }
45 }

2.屏幕旋转

可以这样设置：

对应的代码设置：

1 private void Awake()
2     {
3         Screen.autorotateToLandscapeLeft = true;
4         Screen.autorotateToLandscapeRight = true;
5         Screen.autorotateToPortrait = false;
6         Screen.autorotateToPortraitUpsideDown = false;
7         Screen.orientation = ScreenOrientation.AutoRotation;
8     }
