Unity 3D：加入IOS内购（In-App Purchasing）

编写 内购类，在需要的的地方调用相应方法。

 

using UnityEngine;
using UnityEngine.Purchasing;

public class InAppPurchasing : MonoBehaviour,IStoreListener
{
    //IAP组件相关的对象，m_Controller里存储着商品信息
    private static IStoreController m_Controller;//存储商品信息
    private static  IAppleExtensions m_AppleExtensions;

    private static bool PurchaseAvailable = true;//IAP可用状态
    private static bool InternetAvailable;//是否初始化成功

    public static InAppPurchasing instance;
    void Awake()
    {
        instance = this;
    }
    void OnEnable()
    {
        //如果没有连击网络，关闭IAP功能
        if (Application.internetReachability == NetworkReachability.NotReachable)
        {
            PurchaseAvailable = false;
        }
        else
        {
            PurchaseAvailable = true;
            //如果没有初始化成功
            if (InternetAvailable == false)
            {
                InitUnityPurchase();//初始化
            }
        }
    }
    // Use this for initialization
    void Start()
    {
       
    }
    // Update is called once per frame
    void Update()
    {

    }

    public void InitUnityPurchase()//初始化方法
    {
        var module = StandardPurchasingModule.Instance();//标准采购模块
        var builder = ConfigurationBuilder.Instance(module);//配置模式
        //添加多个ID到builder里，ID命名方式建议字母+数字结尾，比如ShuiJing_1,ShuiJing_2，
        //注意ProductType的类型，Consumable是可以无限购买(比如水晶)，NonConsumable是只能购买一次(比如关卡)，Subscription是每月订阅(比如VIP)
        for (int i = 0; i < 商品数量; i++)
        {
            builder.AddProduct("你的商品ID_" + i.ToString(), ProductType.Consumable);
        }
        //开始初始化
        UnityPurchasing.Initialize(this, builder);
    }
    public void OnInitialized(IStoreController controller, IExtensionProvider extensions)//初始化成功回调
    {
        m_Controller = controller;
        m_AppleExtensions = extensions.GetExtension();
        m_AppleExtensions.RegisterPurchaseDeferredListener(OnDeferred);//登记 购买延迟 监听器
        InternetAvailable = true;//初始化成功
        Debug.Log("IAP初始化成功");
    }
    public void OnInitializeFailed(InitializationFailureReason error)//初始化失败回调
    {
        InternetAvailable = false;
        if (error == InitializationFailureReason.PurchasingUnavailable)
        {
            print("手机设置了禁止APP内购");
        }
        Debug.Log("IAP初始化失败");
    }
    public void OnPurchaseFailed(Product item, PurchaseFailureReason r)//购买失败回调
    {
        print("购买失败");
    }

    public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs e)//购买成功回调
    {
        return 0;//complete 购买完成
        return 1;//pending 未购买
    }

    private void OnDeferred(Product item)//购买延迟提示
    {
        print("网速慢");
    }

    public void OnPurchaseClicked(int ButtonId)//发起购买函数，在你的商品按钮上拖这个方法进入
    {
        m_Controller.InitiatePurchase("你的商品ID_" + ButtonId.ToString());
    }
}
