关于AppStore IAP的新旧Receipt
iOS7.0后，SKPayment的property transactionReceipt变成了DEPRECATED。
建议使用新接口来实现receipt的获取。
[[[NSBundle mainBundle] appStoreReceiptURL] dataWithContentsOfURL:receiptURL];
如果使用了IAP，Apple官方的建议是使用下列代码来处理：
NSData *receipt = nil;
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
// Load resources for iOS 6.1 or earlier
receipt = transaction.transactionReceipt;
} else {
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
receipt = [NSData dataWithContentsOfURL:receiptURL];
}
上面的代码很容易以为，新旧接口取得的receipt格式是一致的。其实不然。
在NtUniSdk里面,iOS官方渠道的易信和网易通行证使用了IAP,然后使用了上述Apple官方建议的代码，结果就是receipt格式不一致，计费验证不通过，把接入SDK的G3坑了一顿。
原来旧接口返回的receipt如下：
2014-07-24 15:53:51.284 [NetEase]iOSNtUniSdkFrameworkDemo[22831:4107] [NtUniSdk] IAP jsonResponse: {

};

}
而新接口返回的receipt：

}
新旧receipt在验证API接口方面无变化，变化主要在于返回的jsonResponese格式。 新的jsonResponese格式官网文档如下：
Receipt Fields https://developer.apple.com/library/ios/releasenotes/General/ValidateAppStoreReceipt/Chapters/ReceiptFields.html#//apple_ref/doc/uid/TP40010573-CH106-SW1
下面是程序中实际输出jsonResponese的Log，值得注意的有receipt字段中的in_app字段可能包含多个transaction的receipt。 客户端APP中的新接口每次读取将读取出还没读取过的所有receipt，当上一次transaction完成后，但没有成功调用到读取receipt接口时，即将出现多条，如下第二条Log所示。

Apple的IAP一直存在一个比较蛋疼的问题，在IAP的交易订单上没有填写额外信息的地方。由于存在网游的账号和AppStore支付账号两套系统，道具发放一直存在着可能在支付过程意外中断而导致漏洞的情况。iOS7.0在SKPayment中提供了一个applicationUsername属性用于填写用户信息，不过鉴于iOS7.0－的系统中没有该属性，在短时间内对这种意外情况改善也不大。
