支持多平台的Assetbundle的应用示例，贴代码，供学习！

这里不同平台的StreamingAssets是不同的，所以我们要写预处理！

using UnityEngine;
using System.Collections;

public class RunScript : MonoBehaviour
{
	

	    //不同平台下StreamingAssets的路径是不同的，这里需要注意一下。
	    public static readonly string PathURL =
#if UNITY_ANDROID
		"jar:file://" + Application.dataPath + "!/assets/";
#elif UNITY_IPHONE
		Application.dataPath + "/Raw/";
#elif UNITY_STANDALONE_WIN || UNITY_EDITOR
	"file://" + Application.dataPath + "/StreamingAssets/";
#else
        string.Empty;
#endif
	
	void OnGUI()
	{
		if(GUILayout.Button("Main Assetbundle"))
		{
			//StartCoroutine(LoadMainGameObject(PathURL + "Prefab0.assetbundle"));
			//StartCoroutine(LoadMainGameObject(PathURL +  "Prefab1.assetbundle"));
		
			StartCoroutine(LoadMainCacheGameObject(PathURL + "Prefab0.assetbundle"));
			StartCoroutine(LoadMainCacheGameObject(PathURL +  "Prefab1.assetbundle"));
		}
		
		if(GUILayout.Button("ALL Assetbundle"))
		{
			StartCoroutine(LoadALLGameObject(PathURL + "ALL.assetbundle"));
		}
		
		if(GUILayout.Button("Open Scene"))
		{
			StartCoroutine(LoadScene());
		}
		
	}
	
	//读取一个资源
	
	private IEnumerator LoadMainGameObject(string path)
	{
		 WWW bundle = new WWW(path);
		 
		 yield return bundle;
		 
		 //加载到游戏中
		 yield return Instantiate(bundle.assetBundle.mainAsset);
		 
		 bundle.assetBundle.Unload(false);
	}
	
	//读取全部资源
	
	private IEnumerator LoadALLGameObject(string path)
	{
		 WWW bundle = new WWW(path);
		 
		 yield return bundle;
		 
		 //通过Prefab的名称把他们都读取出来
		 Object  obj0 =  bundle.assetBundle.Load("Prefab0");
		 Object  obj1 =  bundle.assetBundle.Load("Prefab1");
		
		 //加载到游戏中	
		 yield return Instantiate(obj0);
		 yield return Instantiate(obj1);
		 bundle.assetBundle.Unload(false);
	}
	
	private IEnumerator LoadMainCacheGameObject(string path)
	{
		 WWW bundle = WWW.LoadFromCacheOrDownload(path,5);
		 
		 yield return bundle;
		 
		 //加载到游戏中
		 yield return Instantiate(bundle.assetBundle.mainAsset);
		 
		 bundle.assetBundle.Unload(false);
	}
	
	
	private IEnumerator LoadScene()
	{
		 WWW download = WWW.LoadFromCacheOrDownload ("file://"+Application.dataPath + "/MyScene.unity3d", 1);
		  yield return download;
		  var bundle = download.assetBundle;
  		  Application.LoadLevel ("Level");
	}
	
}
