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]; }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]; }// 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:ProductID andInfo:result]; } NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:result options:NSJSONReadingAllowFragments error:nil]; //NSLog(@"RecivedVerifyPruchaseDict：%@", dict); if (dict != nil) { // 验证成功,通知代理 [self.delegate IAPToolBoughtProductSuccessedWithProductID:ProductID andInfo:dict receipt:encodeStr]; } else { //验证失败,通知代理 [self.delegate IAPToolCheckFailedWithProductID:ProductID andInfo:result]; } }] resume]; }非消耗型项目一定要有恢复商品的功能，不会被拒绝哦～
