[UGUI]图文混排(三)：资源管理

1.图文混排中的资源，主要是图片。

2.所谓的资源管理，可以分为资源对象池和资源加载这两部分。这里是为图文混排单独做一套资源管理，当然也可以改为调用项目中的资源管理。

RichTextResourceManager.cs

 1 using UnityEngine;  2 using System.Collections.Generic;  3 using UnityEngine.UI;  4 using System;  5 #if UNITY_EDITOR  6 using UnityEditor;  7 #endif  8   9 public enum RichTextResourceType 10 { 11     Image, 12 } 13  14 public class RichTextResourceManager : CSharpSingletion<RichTextResourceManager> { 15  16     private Dictionary<RichTextResourceType, List<GameObject>> typeGoDic = new Dictionary<RichTextResourceType, List<GameObject>>(); 17     private DefaultControls.Resources resources = new DefaultControls.Resources(); 18  19     public void SetPoolObject(RichTextResourceType type, GameObject go) 20     { 21         if (!typeGoDic.ContainsKey(type)) 22         { 23             List<GameObject> goList = new List<GameObject>(); 24             goList.Add(go); 25             typeGoDic.Add(type, goList); 26         } 27         else 28         { 29             typeGoDic[type].Add(go); 30         } 31         go.SetActive(false); 32     } 33  34     public GameObject GetPoolObject(RichTextResourceType type) 35     { 36         GameObject go = null; 37         if (typeGoDic.ContainsKey(type)) 38         { 39             if (typeGoDic[type].Count > 0) 40             { 41                 go = typeGoDic[type][0]; 42                 if (go) 43                 { 44                     go.SetActive(true); 45                     typeGoDic[type].Remove(go); 46                     return go; 47                 } 48             } 49         } 50         go = CreatePoolObject(type); 51         return go; 52     } 53  54     private GameObject CreatePoolObject(RichTextResourceType type) 55     { 56         GameObject go = null; 57         if (type == RichTextResourceType.Image) 58         { 59             go = CreateImage(); 60         } 61         return go; 62     } 63  64     public void LoadSprite(string path, Action<Sprite> callback) 65     { 66 #if UNITY_EDITOR 67         Sprite sprite = AssetDatabase.LoadAssetAtPath<Sprite>("Assets/" + path + ".png"); 68         if ((sprite != null) && (callback != null)) 69         { 70             callback(sprite); 71         } 72 #endif 73     } 74  75     public void LoadSprite(string path, Action<Sprite[]> callback) 76     { 77 #if UNITY_EDITOR 78         Sprite[] sprites = AssetDatabase.LoadAllAssetsAtPath("Assets/" + path + ".png") as Sprite[]; 79         if ((sprites != null) && (callback != null)) 80         { 81             callback(sprites); 82         } 83 #endif 84     } 85  86     public void SetSprite(string path, Image image) 87     { 88         LoadSprite(path, (Sprite sprite) => { image.sprite = sprite; }); 89     } 90  91     private GameObject CreateImage() 92     { 93         GameObject go = DefaultControls.CreateImage(resources); 94         go.layer = LayerMask.NameToLayer("UI"); 95         Image image = go.GetComponent<Image>(); 96         image.raycastTarget = false; 97         return go; 98     } 99 }
