上代码：

using UnityEngine;
 
[RequireComponent(typeof(Camera))]
public class SpriteAdapter : MonoBehaviour {
 
    [System.Serializable]
    public class SpriteInfo
    {
        public SpriteRenderer Value = null;
        public EFillModel Model = EFillModel.ShowAll;
    }
 
    public enum EFillModel

        /// <summary>

        WithHeight,
        /// <summary>

        WithWidth
        
    }
 
    public enum EUpdateType
    {
        /// <summary>

        /// </summary>
        UpdateOnAwake,

        /// </summary>
        UpdateOnViewportChanged
    }
 
    public EUpdateType TickType = EUpdateType.UpdateOnAwake;
    public SpriteInfo[] Members;

    float ScreenRatio;
 
    void Awake () {
        Viewport = GetComponent<Camera>();
        UpdateAll();
    }
 
    private void LateUpdate()
    {
        if (TickType != EUpdateType.UpdateOnViewportChanged) return;
        if (ScreenRatio != Viewport.aspect)
        {
            UpdateAll();
        }
    } 
 
    /// <summary>

    /// </summary>
    void UpdateAll()
    {
        for (int i = 0; i < Members.Length; i++)
        {
            AdaptSpriteRender(Members[i]);
        }
 
        ScreenRatio = Viewport.aspect;
    }
 
    /// <summary>
    /// 使sprite铺满整个屏幕
    /// </summary>
    private void AdaptSpriteRender(SpriteInfo _spriteInfo)
    {
        SpriteRenderer spriteRenderer = _spriteInfo.Value;
        Vector3 scale = spriteRenderer.transform.localScale;
        float cameraheight = Viewport.orthographicSize * 2;
        float camerawidth = cameraheight * Viewport.aspect;
        float texr = (float)spriteRenderer.sprite.texture.width / spriteRenderer.sprite.texture.height;
        float viewr = camerawidth / cameraheight;
        switch (_spriteInfo.Model)
        {
            case EFillModel.WithHeight:
                //> 根据图片高度进行填充
                scale *= cameraheight / spriteRenderer.bounds.size.y;
                break;
            case EFillModel.WithWidth:
                //> 根据图片宽度进行填充
                scale *= camerawidth / spriteRenderer.bounds.size.x;
                break;
            case EFillModel.Full: 
                //> 填满整个屏幕
                if (viewr >= texr)
                {
                    if(viewr >= 1 && texr >= 1 || texr < 1)
                        scale *= camerawidth / spriteRenderer.bounds.size.x;
                    else
                        scale *= cameraheight / spriteRenderer.bounds.size.y;
                }
                else
                {
                    if (viewr <= 1 || texr > 1)
                        scale *= cameraheight / spriteRenderer.bounds.size.y; 
                    else
                        scale *= camerawidth / spriteRenderer.bounds.size.x;
                }
                break;
            default:
                //> 在屏幕上显示图片的全部内容
                if (viewr >= texr)
                {
                    scale *= cameraheight / spriteRenderer.bounds.size.y;
                }
                else
                {
                    scale *= camerawidth / spriteRenderer.bounds.size.x;
                }
                break;
        }
        spriteRenderer.transform.localScale = scale; 
    } 
}

如何使用：

1.把脚本挂在Camera上

2.把需要进行屏幕适配的SpriteRender对象放在Member队列中

3.选择更新类型EUpdateType、选择适配类型EFillModel即可
