ios7.0后ios支付成功返回的票據Receipt的獲取方式有了新的方式，
原來的SKPaymentTransaction中的transactionReceipt屬性獲取票據的方式已經過期，雖然還能使用，但是蘋果官方建議使用新的
新版的獲取Receipt的方式是通過新接口如下
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
當然，低于ios7.0的還是需要使用老版本接口，對兩種版本進行適配的代碼如下：
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]; } }}判斷是否是沙盒支付，新版本可以直接判斷receiptURL中是否存在“sandbox“
老版本receipt可以解析NSData 查看environment是否為Sandbox來判斷
+ (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; }}客戶端receipt驗證方式：
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"];//根據是否是沙盒支付驗證取正確的地址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：

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;}...... 可能存在多條);"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，新版中數據結構中的in_app字段，可能包含多個transaction的receipt。當完成transaction后，還沒有成功調用讀取過receipt的接口，那下一次讀取recept時會把所有的都讀取出來，從而出現多條數據。
一般開發商app支付都有自己的支付系統，可能每次下單之前都會創建自己的訂單號，需要與ios支付后返回的receipt一一對應，這種情況下如何處理還需要注意。
