一、分步骤说明

1、获取商品列表

由于苹果服务器返回很慢，并且一般我们都会有一个自己的商店界面，就不必向苹果服务器去请求商品列表了。
购买时传要购买商品的ID（在App Store Connect 创建的产品ID）就可以了。

/// 请求苹果的服务器能够销售的商品
/// @param products 【产品ID】
- (void)requestProductsWithProductArray:(NSArray *)products
{NSSet *set = [[NSSet alloc] initWithArray:products];// "异步"请求苹果能否销售SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:set];request.delegate = self;// 启动请求[request start];
}

2、苹果服务器返回的可购买商品

#pragma mark - SKProductsRequestDelegate/// 获取请求结果，把商品加入到自己的商品列表
/// @param request 请求
/// @param response 返回结果
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{if (self.productDict == nil) {self.productDict = [NSMutableDictionary dictionaryWithCapacity:response.products.count];}NSMutableArray *productArray = [NSMutableArray array];for (SKProduct *product in response.products) {//NSLog(@"%@", product.productIdentifier);[self.productDict setObject:product forKey:product.productIdentifier];[productArray addObject:product];}// 通知代理[self.delegate IAPToolGotProducts:productArray];
}

3、下单购买商品

拿到了苹果服务器返回的可购买商品后，下单进行购买。

/// 下单购买商品
/// @param productID 商品ID
- (void)buyProduct:(NSString *)productID
{// 从自己的商品列表中取出要购买的商品SKProduct *product = self.productDict[productID];// 要购买的产品生成单据SKPayment *payment = [SKPayment paymentWithProduct:product];// 加入队列准备付款购买[[SKPaymentQueue defaultQueue] addPayment:payment];
}

4、购买队列状态变化，判断购买状态是否成功

typedef NS_ENUM(NSInteger, SKPaymentTransactionState) {SKPaymentTransactionStatePurchasing,    //交易被添加到服务器队列中SKPaymentTransactionStatePurchased,     // 交易正在排队，用户已被收费。客户应完成交易SKPaymentTransactionStateFailed,        // 交易在添加到服务器队列之前被取消或失败SKPaymentTransactionStateRestored,      // 交易已从用户的购买历史中恢复SKPaymentTransactionStateDeferred,   // 等待外部操作
};

#pragma mark - SKPaymentTransaction Observer
#pragma mark 购买队列状态变化，判断购买状态是否成功/// 当交易数组发生更改(添加或状态更改)时发送。客户端应该检查交易的状态并适当地完成
/// @param queue 队列
/// @param transactions 交易
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{// 处理结果for (SKPaymentTransaction *transaction in transactions) {NSLog(@"队列状态变化 %@", transaction);// 如果收据状态是购买完成switch (transaction.transactionState) {case SKPaymentTransactionStatePurchased: { // 完成交易//NSLog(@"购买完成 %@", transaction.payment.productIdentifier);if (self.CheckAfterPay) {// 需要向苹果服务器验证一下// 通知代理[self.delegate IAPToolBeginCheckingdWithProductID:transaction.payment.productIdentifier];// 验证购买凭据[self verifyPruchaseWithID:transaction.payment.productIdentifier];} else {// 不需要向苹果服务器验证// 验证凭据，获取到苹果返回的交易凭据// appStoreReceiptURL iOS7.0增加的，购买交易完成后，会将凭据存放在该地址NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];// 从沙盒中获取到购买凭据NSData *receiptData = [NSData dataWithContentsOfURL:receiptURL];NSString *encodeStr = [receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];// 通知代理[self.delegate IAPToolBoughtProductSuccessedWithProductID:transaction.payment.productIdentifierandInfo:nil receipt:encodeStr];}// 将交易从交易队列中删除[[SKPaymentQueue defaultQueue] finishTransaction:transaction];}break;case SKPaymentTransactionStateRestored: { // 恢复购买//NSLog(@"恢复成功 :%@", transaction.payment.productIdentifier);// 通知代理[self.delegate IAPToolRestoredProductID:transaction.payment.productIdentifier];// 将交易从交易队列中删除[[SKPaymentQueue defaultQueue] finishTransaction:transaction];}break;case SKPaymentTransactionStateFailed: { // 加入队列之前取消或失败// 将交易从交易队列中删除[[SKPaymentQueue defaultQueue] finishTransaction:transaction];//NSLog(@"交易失败");[self.delegate IAPToolCanceldWithProductID:transaction.payment.productIdentifier];}break;case SKPaymentTransactionStatePurchasing: { // 交易被添加到服务器队列中NSLog(@"正在购买");}break;default: {NSLog(@"state:%ld",(long)transaction.transactionState);// 将交易从交易队列中删除[[SKPaymentQueue defaultQueue] finishTransaction:transaction];}break;}}
}

5、交易验证

// 发送网络POST请求，对购买凭据进行验证
// 沙盒测试 https://sandbox.itunes.apple.com/verifyReceipt
// 正式环境 https://buy.itunes.apple.com/verifyReceipt

当SKPaymentTransactionStatePurchased 完成交易时，我们需要验证一下。
a、拿到收据上传到自己的服务器进行验证。

NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];// 从沙盒中获取到购买凭据NSData *receiptData = [NSData dataWithContentsOfURL:receiptURL];NSString *encodeStr = [receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];

b、如果是单机就本地向苹果服务器请求验证。

/// 验证购买凭据
/// @param ProductID 商品ID
- (void)verifyPruchaseWithID:(NSString *)ProductID
{// 验证凭据，获取到苹果返回的交易凭据// appStoreReceiptURL iOS7.0增加的，购买交易完成后，会将凭据存放在该地址NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];// 从沙盒中获取到购买凭据NSData *receiptData = [NSData dataWithContentsOfURL:receiptURL];// 发送网络POST请求，对购买凭据进行验证//In the test environment, use https://sandbox.itunes.apple.com/verifyReceipt//In the real environment, use https://buy.itunes.apple.com/verifyReceipt// Create a POST request with the receipt data.NSURL *url = [NSURL URLWithString:checkURL];NSLog(@"checkURL:%@",checkURL);// 国内访问苹果服务器比较慢，timeoutInterval需要长一点NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:20.0f];request.HTTPMethod = @"POST";NSString *encodeStr = [receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];NSString *payload = [NSString stringWithFormat:@"{\"receipt-data\" : \"%@\"}", encodeStr];NSData *payloadData = [payload dataUsingEncoding:NSUTF8StringEncoding];request.HTTPBody = payloadData;// 提交验证请求，并获得官方的验证JSON结果[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {NSData *result = data;// 官方验证结果为空if (result == nil) {//NSLog(@"验证失败");//验证失败,通知代理[self.delegate IAPToolCheckFailedWithProductID:ProductIDandInfo:result];}NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:resultoptions:NSJSONReadingAllowFragments error:nil];//NSLog(@"RecivedVerifyPruchaseDict：%@", dict);if (dict != nil) {// 验证成功,通知代理[self.delegate IAPToolBoughtProductSuccessedWithProductID:ProductIDandInfo:dict receipt:encodeStr];} else {//验证失败,通知代理[self.delegate IAPToolCheckFailedWithProductID:ProductIDandInfo:result];}}] resume];
}

6、拿到的收据信息是，此App所有购买的记录

{environment = Sandbox;receipt =     {"adam_id" = 0;"app_item_id" = 0;"application_version" = 5;"bundle_id" = "com.fly.app";"download_id" = 0;"in_app" =         ({"is_trial_period" = false;"original_purchase_date" = "2020-07-04 12:56:09 Etc/GMT";"original_purchase_date_ms" = 1587214569000;"original_purchase_date_pst" = "2020-07-04 05:56:09 America/Los_Angeles";"original_transaction_id" = 1000000653555670;"product_id" = VIP1;"purchase_date" = "2020-07-04 12:56:09 Etc/GMT";"purchase_date_ms" = 1587214569000;"purchase_date_pst" = "2020-07-04 05:56:09 America/Los_Angeles";quantity = 1;"transaction_id" = 1000000653555670;},{"is_trial_period" = false;"original_purchase_date" = "2020-07-04 14:38:05 Etc/GMT";"original_purchase_date_ms" = 1587220685000;"original_purchase_date_pst" = "2020-04-18 07:38:05 America/Los_Angeles";"original_transaction_id" = 1000000653568586;"product_id" = VIP2;"purchase_date" = "2020-07-04 14:38:05 Etc/GMT";"purchase_date_ms" = 1587220685000;"purchase_date_pst" = "2020-07-04 07:38:05 America/Los_Angeles";quantity = 1;"transaction_id" = 1000000653568586;});"original_application_version" = "1.0";"original_purchase_date" = "2013-08-01 07:00:00 Etc/GMT";"original_purchase_date_ms" = 1375340400000;"original_purchase_date_pst" = "2013-08-01 00:00:00 America/Los_Angeles";"receipt_creation_date" = "2020-07-04 07:08:53 Etc/GMT";"receipt_creation_date_ms" = 1593832014000;"receipt_creation_date_pst" = "2020-07-04 00:08:53 America/Los_Angeles";"receipt_type" = ProductionSandbox;"request_date" = "2020-07-04 07:08:55 Etc/GMT";"request_date_ms" = 1593832035030;"request_date_pst" = "2020-07-04 00:08:55 America/Los_Angeles";"version_external_identifier" = 0;};status = 0;
}

7、恢复商品

非消耗型项目一定要有恢复商品的功能，不会被拒绝哦～

/// 恢复商品
- (void)restorePurchase
{// 恢复已经完成的所有交易.（仅限永久有效商品）[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
