一秽荞、后臺(tái)商品配置

1. 進(jìn)入蘋果開發(fā)者后臺(tái)扬跋，填寫稅務(wù)信息钦听，銀行信息（不填會(huì)出現(xiàn)購(gòu)買失斊由稀）卒煞；
2. 選擇你要添加內(nèi)購(gòu)的應(yīng)用畔裕，找到 In-App Purchases 選項(xiàng)扮饶，點(diǎn)擊 Manage；
   
   選擇你要添加內(nèi)購(gòu)的應(yīng)用
3. 點(diǎn)擊添加商品靠粪，然后完善商品信息；

注意：這里要填寫所以信息昔善，包括截圖畔乙，直到狀態(tài)為 Ready to Submit 為止牲距，不然也會(huì)出現(xiàn)購(gòu)買失敗

添加商品

二牍鞠、unity API接入

1. 點(diǎn)擊 manage service 打開services面板萤晴；

   
   
   Services
2. 選擇一個(gè)組織店读，沒(méi)有的話創(chuàng)建一個(gè)屯断；

3. 根據(jù)提示打開Purchasing殖演，導(dǎo)入包紧武，如果需要更新阻星，請(qǐng)點(diǎn)擊update妥箕；

   
   
   導(dǎo)入

4. 購(gòu)買功能可以通過(guò)unity提供的組件實(shí)現(xiàn)，也可以用代碼實(shí)現(xiàn)缆蝉，我們選擇用代碼實(shí)現(xiàn)。

   
   
   Unity IAP

三诸尽、代碼部分

using UnityEngine;
using UnityEngine.Purchasing;
using System;

public class PurchasingManager : IStoreListener
{
    public static readonly PurchasingManager Instance = new PurchasingManager();
    private IStoreController storeController;
    private static IExtensionProvider extensionProvider;
    private static IAppleExtensions appleExtension;
    //private static IGooglePlayStoreExtensions googleExtension;

    private Action<string> failedCallback;
    private Action<Product> successedCallback;

    PurchasingManager()
    {
        
    }

    /// <summary>

        if (!IsInitialized())
        {
            OnFailedCallback("Not initialized.");
            return;
        }

        var product = storeController.products.WithID(_productId);
        if (product == null || !product.availableToPurchase)
        {

四、打包測(cè)試

1. 包名一定和你后臺(tái)的包名對(duì)應(yīng)仲闽；

2. 商品ID和類型也要和后臺(tái)對(duì)應(yīng)蔼囊；

3. 在蘋果開發(fā)者后臺(tái)的用戶和訪問(wèn)菜單中找到沙盒畏鼓，添加沙盒測(cè)試人員壶谒；

   
   
   添加測(cè)試員

4. 在App Store登陸該測(cè)試賬號(hào)让禀；

5. 點(diǎn)擊要購(gòu)買的商品巡揍，輸入密碼腮敌，彈出以下彈窗的時(shí)候說(shuō)明購(gòu)買成功了

   
   
   購(gòu)買成功

走到這里說(shuō)明你接成功了糜工，恭喜你捌木。

暫時(shí)寫這么多刨裆，有不懂的或者需要補(bǔ)充的請(qǐng)私信我。
