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

using UnityEngine;

[DisallowMultipleComponent]
[RequireComponent(typeof(RectTransform))]
public class SafeAreaRect : MonoBehaviour
{
    private RectTransform rectTransform;
    private ScreenOrientation lastScreenOrientation;

    private void Awake()
    {
        rectTransform = GetComponent<RectTransform>();
        lastScreenOrientation = Screen.orientation;
        ChangeRect();
    }

    void Update()
    {
        if (lastScreenOrientation != Screen.orientation)
        {
            lastScreenOrientation = Screen.orientation;
            ChangeRect();
        }
        //print(Screen.safeArea);
        //print(Screen.orientation);
        //print(Application.isMobilePlatform);
        //print(Screen.width + "_" + Screen.height);
    }

    private void ChangeRect()
    {
        ScreenOrientation screenOrientation = Screen.orientation;
        Rect safeArea = Screen.safeArea;
        if (screenOrientation == ScreenOrientation.Portrait || screenOrientation == ScreenOrientation.PortraitUpsideDown) //竖屏
        {
            rectTransform.anchorMin = new Vector2(safeArea.x / Screen.width, safeArea.y / Screen.height);
            rectTransform.anchorMax = new Vector2((safeArea.x + safeArea.width) / Screen.width, (safeArea.y + safeArea.height) / Screen.height);
        }
        else //横屏
        {
            rectTransform.anchorMin = new Vector2(safeArea.x / Screen.width, safeArea.y / Screen.height);
            rectTransform.anchorMax = new Vector2((safeArea.x + safeArea.width) / Screen.width, (safeArea.y + safeArea.height) / Screen.height);
        }
    }
}

 

2.屏幕旋转

可以这样设置：

对应的代码设置：

private void Awake()
    {
        Screen.autorotateToLandscapeLeft = true;
        Screen.autorotateToLandscapeRight = true;
        Screen.autorotateToPortrait = false;
        Screen.autorotateToPortraitUpsideDown = false;
        Screen.orientation = ScreenOrientation.AutoRotation;
    }
