Unity3d接入IOS內購__IOS

利用Unity3d製作完畢遊戲發布到appstore，有時會做遊戲內購買虛擬物品，也就是內購。

在Ios開發中叫做：In App Purchase，簡稱IAP

那麼如何在unity3d內嵌入IPA呢。幾經輾轉，多方搜尋，摸索出點經驗，分享給大家，如有疏漏，還請指教。

當然也有人們寫好的外掛程式可用，我覺得自己寫的才用著順手。

 

一、準備條件：

1、 申請蘋果開發人員帳號。後台先建立認證，在建立應用，填寫應用詳情，建立測試用的帳號，建立內購項目。

這雷根據需要建立consumable（每次都需要購買）或者non-consumable的（購買一次一直可用，就是如果買過可以恢複購買）內購項目。

如下我們建立了non-consumable類型，名稱“Package_2”,這個名稱僅能使用一次，即使刪除了也不能夠再次利用。

 

建立測試人員帳號，可以免費測試購買本開發人員帳號下面所有應用的物品：

 

2、簡單瞭解ios開發的Object-C語言，主要是用來做內購，詳細請百度：

3、簡單瞭解IPA

詳細請參見：StoreKit Guide(In App Purchase)翻譯

http://yarin.blog.51cto.com/1130898/549141

4、瞭解unity3d與ios通訊，詳細參見：為iOS建立外掛程式 Building Plugins for iOS

http://game.ceeger.com/Manual/PluginsForIOS.html

 

二、下面我們單獨建立一個例子來示範：

1、 建立工程，切換到ios平台、建立空gameobject，改名為Main，建立點擊按鈕觸發購買的指令碼，掛在Main上面。建立平台檔案，下面建立子檔案夾IOS。

2、 在設定裡面修改包名，改為你自己在appstore後台建立的名稱

IPADemo裡面編寫與ios通訊代碼以及購買代碼，其中內購商品名稱修改為自己appstore後台定義的：private stringproduct = "Package_2";

 

using UnityEngine;

using System.Collections;

using System.Collections.Generic;

using System.Runtime.InteropServices;

 

public class IPADemo : MonoBehaviour {

 

         publicList<string> productInfo = new List<string>();

 

         privatestring product = "Package_2";

        

         [DllImport("__Internal")]

         privatestatic extern void TestMsg();//測試資訊發送

        

         [DllImport("__Internal")]

         privatestatic extern void TestSendString(string s);//測試發送字串

        

         [DllImport("__Internal")]

         privatestatic extern void TestGetString();//測試接收字串

        

         [DllImport("__Internal")]

         privatestatic extern void InitIAPManager();//初始化

        

         [DllImport("__Internal")]

         privatestatic extern bool IsProductAvailable();//判斷是否可以購買

        

         [DllImport("__Internal")]

         privatestatic extern void RequstProductInfo(string s);//擷取商品資訊

        

         [DllImport("__Internal")]

         privatestatic extern void BuyProduct(string s);//購買商品

        

         //測試從xcode接收到的字串

         voidIOSToU(string s)

         {

                   Debug.Log("[MsgFrom ios]"+s);

         }

        

         //擷取product列表

         voidShowProductList(string s){

                   productInfo.Add(s);

         }

        

         //擷取商品回執

         voidProvideContent(string s)

         {

                   Debug.Log("[MsgFrom ios]proivideContent : "+s);

         }

         voidStart ()

         {

                   InitIAPManager();

         }

         voidUpdate ()

         {                          

         }

        

         voidOnGUI()

         {                

                   if(Btn("GetProducts")){

                            if(!IsProductAvailable())

                                     thrownew System.Exception("IAP not enabled");

                            productInfo= new List<string>();

                            RequstProductInfo(product);

                   }

                  

                   GUILayout.Space(40);

                  

                   for(inti=0; i<productInfo.Count; i++){

                            if(GUILayout.Button(productInfo[i],GUILayout.Height (100), GUILayout.MinWidth (200))){

                                     string[]cell = productInfo[i].Split('\t');

                                     Debug.Log("[Buy]"+cell[cell.Length-1]);

                                     BuyProduct(cell[cell.Length-1]);

                            }

                   }

         }

        

         boolBtn(string msg){

                   GUILayout.Space(100);

                   return       GUILayout.Button (msg,GUILayout.Width(200),GUILayout.Height(100));

         }

}

 

還需要在xcode裡面編寫內購代碼然後複製到平台下，ios檔案夾下：

只能在真機上才能出現內購窗，Unity中運行效果如下：

 

3、匯出ios工程，在mac上xcode中開啟：

4、加入依賴項，libz，storekit：

5、在真機上運行，首先獲得商品列表，然後點擊購買，然後在彈出的帳號密碼框裡面修改為沙箱測試帳號。即可測試購買成功。
