一.內購了解
1.內購的概述
內購分成:在訂閱者使用付費服務的首年內，您的收益率為 70%。當訂閱者為同一訂閱群組中的訂閱產品累積一年的付費服務后，您的收益率將提高至 85%。同一群組中的升級訂閱、降級訂閱和跨級訂閱不會中斷付費服務的天數。轉換至不同群組的訂閱將重置付費服務的天數。賺取 85% 訂閱價格這一規則適用於2016年6月之后生效的訂閱續期。
消耗型項目
用戶可以購買各種消耗型項目 (例如游戲中的生命或寶石) 以繼續 app 內進程。消耗型項目只可使用一次，使用之后即失效，必須再次購買。
非消耗型項目
用戶可購買非消耗型項目以提升 app 內的功能。非消耗型項目只需購買一次，不會過期 (例如修圖 app 中的其他濾鏡)。
自動續期訂閱
用戶可購買固定時段內的服務或更新的內容 (例如雲存儲或每周更新的雜志)。除非用戶選擇取消，否則此類訂閱會自動續期。
非續期訂閱
用戶可購買有時限性的服務或內容 (例如線上播放內容的季度訂閱)。此類的訂閱不會自動續期，用戶需要逐次續訂。
3.內購流程圖
4.協議、稅務和銀行業務 信息填寫
這一塊內容主要是在你的開發者賬號上查看協議，輸入聯系人信息，輸入銀行信息和提交報稅表。具體可以查看一下鏈接
https://help.apple.com/app-store-connect/?lang=zh-cn#/devb6df5ee51
二.開發部分
1.創建內購商品
首先點管理，點擊+號創建你業務邏輯需要的產品類型，如上圖。
填寫完信息后，就是這樣子，我這邊都是消耗性產品類型，如上圖。這樣子產品就創建好了。
2.添加沙箱測試人員
首先選擇用戶與訪問，第二步找到測試員，第三部選擇添加+，填寫你的測試賬號信息，最后就生成了下圖4的測試賬號信息了。（注意：測試賬號信息是和開發者賬號相關聯的）
3.代碼實踐部分
首先說兩個點，為了防止丟單，一般采用單例(整個應用都存在)和把單據信息存儲本地策略（只要沒有驗證成功就不清除本地緩存）。好了上代碼
3.1.單例類
#import <Foundation/Foundation.h>
#import <StoreKit/StoreKit.h>
NS_ASSUME_NONNULL_BEGIN
typedef enum {
IAPPurchSuccess = 0,//購買成功
IAPPurchFailed = 1, //購買失敗el
IAPPurchCancel = 2, //取消購買
IAPPurchVerFailed = 3, //訂單校驗失敗
IAPPurchVerSuccess = 4, //訂單校驗成功
IAPPurchNotArrow = 5, //不允許內購
}IAPPurchType;
typedef void(^IAPCompletionHandleBlock)(IAPPurchType type, NSData *data);
@interface JLKJApplePay : NSObject
@property(nonatomic,copy)NSString*idNo;
+ (instancetype)shareIAPManager;
//添加內購產品
- (void)addPurchWithProductID:(NSString *)product_id completeHandle:(IAPCompletionHandleBlock)handle;
@end
NS_ASSUME_NONNULL_END
/*注意事項：
1.沙盒環境測試appStore內購流程的時候，請使用沒越獄的設備。
2.請務必使用真機來測試，一切以真機為准。
3.項目的Bundle identifier需要與您申請AppID時填寫的bundleID一致，不然會無法請求到商品信息。
4.如果是你自己的設備上已經綁定了自己的AppleID賬號請先注銷掉,否則你哭爹喊娘都不知道是怎么回事。
5.訂單校驗 蘋果審核app時，仍然在沙盒環境下測試，所以需要先進行正式環境驗證，如果發現是沙盒環境則轉到沙盒驗證。
識別沙盒環境訂單方法：
1.根據字段 environment = sandbox。
2.根據驗證接口返回的狀態碼,如果status=21007，則表示當前為沙盒環境。
蘋果反饋的狀態碼：
21000App Store無法讀取你提供的JSON數據
21002 訂單數據不符合格式
21003 訂單無法被驗證
21004 你提供的共享密鑰和賬戶的共享密鑰不一致
21005 訂單服務器當前不可用
21006 訂單是有效的，但訂閱服務已經過期。當收到這個信息時，解碼后的收據信息也包含在返回內容中
21007 訂單信息是測試用（sandbox），但卻被發送到產品環境中驗證
21008 訂單信息是產品環境中使用，但卻被發送到測試環境中驗證
