ios7.0后ios支付成功返回的票据Receipt的获取方式有了新的方式，

原来的SKPaymentTransaction中的transactionReceipt属性获取票据的方式已经过期，虽然还能使用，但是苹果官方建议使用新的

新版的获取Receipt的方式是通过新接口如下

NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];

当然，低于ios7.0的还是需要使用老版本接口，对两种版本进行适配的代码如下：

NSData*receipt= nil；if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")){//ios after 7.0  NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];  receipt = [NSData dataWithContentsOfURL:receiptURL];  NSString *receiptURLStr = [receiptURL absoluteString];  NSRange rangeSandbox = [receiptURLStr rangeOfString:@"sandbox"];  if (rangeSandbox.location != NSNotFound){    record[kIAPEnvironment] = [NSNumber numberWithInt:1];  }}else{//ios 3.0~7.0  receipt = transaction.transactionReceipt;  NSDictionary *dict = [NSDictionary dictionaryWithContentsOfData:receipt];  if (dict){    NSString *env = [dict objectForKey:@"environment"];    if ([env isEqualToString:@"Sandbox"]) {      record[kIAPEnvironment] = [NSNumber numberWithInt:1];    } }}

判断是否是沙盒支付，新版本可以直接判断receiptURL中是否存在“sandbox“

老版本receipt可以解析NSData 查看environment是否为Sandbox来判断

+ (NSDictionary *)dictionaryWithContentsOfData: (NSData *)data{  CFPropertyListRef plist = CFPropertyListCreateFromXMLData(kCFAllocatorDefault, (__bridge CFDataRef)data,  kCFPropertyListImmutable, NULL);  if(plist == nil) return nil;  if ([(__bridge id)plist isKindOfClass:[NSDictionary class]]){  return (__bridge NSDictionary *)plist;  }else{  CFRelease(plist);  return nil;  }}

客户端receipt验证方式：

NSError *error;NSDictionary *requestContents = @{@"receipt-data": [receipt base64EncodedString]};NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestContentsoptions:0error:&error];if (!requestData) {  return;}// Create a POST request with the receipt data.NSURL *storeURL = [NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"];//根据是否是沙盒支付验证取正确的地址NSMutableURLRequest *storeRequest = [NSMutableURLRequest requestWithURL:storeURL];[storeRequest setHTTPMethod:@"POST"];[storeRequest setHTTPBody:requestData];// Make a connection to the iTunes Store on a background queue.NSOperationQueue *queue = [[NSOperationQueue alloc] init];[NSURLConnection sendAsynchronousRequest:storeRequest queue:queuecompletionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {  if (connectionError) {  /* ... Handle error ... */} else {  NSError *error;  NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data   options:0 error:&error];  if (!jsonResponse) { /* ... Handle error ...*/ }  /* ... Send a response back to the device ... */  }}];

老版本返回格式：

{bid = "com.coodezhang.test";bvrs = "1.0";"item_id" = 892617314;"original_purchase_date" = "2017-12-14 07:43:14 Etc/GMT";"original_purchase_date_ms" = 1626147394550;"original_purchase_date_pst" = "2017-12-14 12:43:14 America/Los_Angeles";"original_transaction_id" = 1000001127239959;"product_id" = "com.coodezhang.test_coins99M_Tier1";"purchase_date" = "2017-12-14 07:43:14 Etc/GMT";"purchase_date_ms" = 1626147394550;"purchase_date_pst" = "2017-12-14 12:43:14 America/Los_Angeles";quantity = 1;"transaction_id" = 1000001127239959;"unique_identifier" = 0000b0124819;"unique_vendor_identifier" = "ASDGF2DB-DSAD-5A21-9611-642A4B9CASDE7";};status = 0;}

新版本返回格式：

{environment = Sandbox;receipt =   {"adam_id" = 0;"app_item_id" = 0;"application_version" = 1;"bundle_id" = "com.coodezhang.test";"download_id" = 0;"in_app" =     ({"is_trial_period" = false;"original_purchase_date" = "2017-12-14 07:18:56 Etc/GMT";"original_purchase_date_ms" = 1513235936000;"original_purchase_date_pst" = "2017-12-13 23:18:56 America/Los_Angeles";"original_transaction_id" = 1000000359369424;"product_id" = "com.coodezhang.test_coins99M_Tier1";"purchase_date" = "2017-12-14 07:18:56 Etc/GMT";"purchase_date_ms" = 1513235936000;"purchase_date_pst" = "2017-12-13 23:18:56 America/Los_Angeles";quantity = 1;"transaction_id" = 1000000359369424;}...... 可能存在多条);"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" = "2017-12-14 07:18:56 Etc/GMT";"receipt_creation_date_ms" = 1513235936000;"receipt_creation_date_pst" = "2017-12-13 23:18:56 America/Los_Angeles";"receipt_type" = ProductionSandbox;"request_date" = "2017-12-14 07:19:23 Etc/GMT";"request_date_ms" = 1513235963829;"request_date_pst" = "2017-12-13 23:19:23 America/Los_Angeles";"version_external_identifier" = 0;};status = 0;}

值得注意的是，新版中数据结构中的in_app字段，可能包含多个transaction的receipt。当完成transaction后，还没有成功调用读取过receipt的接口，那下一次读取recept时会把所有的都读取出来，从而出现多条数据。

一般开发商app支付都有自己的支付系统，可能每次下单之前都会创建自己的订单号，需要与ios支付后返回的receipt一一对应，这种情况下如何处理还需要注意。
