IOS应用内支付返回新旧Receipt适配的方法
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=[[NSBundlemainBundle]appStoreReceiptURL]; NSData*receipt=[NSDatadataWithContentsOfURL: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")){
//iosafter7.0
NSURL*receiptURL=[[NSBundlemainBundle]appStoreReceiptURL];
receipt=[NSDatadataWithContentsOfURL:receiptURL];
NSString*receiptURLStr=[receiptURLabsoluteString];
NSRangerangeSandbox=[receiptURLStrrangeOfString:@"sandbox"];
if(rangeSandbox.location!=NSNotFound){
record[kIAPEnvironment]=[NSNumbernumberWithInt:1];
}
}else{
//ios3.0~7.0
receipt=transaction.transactionReceipt;
NSDictionary*dict=[NSDictionarydictionaryWithContentsOfData:receipt];
if(dict){
NSString*env=[dictobjectForKey:@"environment"];
if([envisEqualToString:@"Sandbox"]){
record[kIAPEnvironment]=[NSNumbernumberWithInt: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{
CFPropertyListRefplist=CFPropertyListCreateFromXMLData(kCFAllocatorDefault,(__bridgeCFDataRef)data,
kCFPropertyListImmutable,NULL);
if(plist==nil)returnnil;
if([(__bridgeid)plistisKindOfClass:[NSDictionaryclass]]){
return(__bridgeNSDictionary*)plist;
}else{
CFRelease(plist);
returnnil;
}
}
客户端receipt验证方式：
NSError*error;
NSDictionary*requestContents=@{
@"receipt-data":[receiptbase64EncodedString]
};
NSData*requestData=[NSJSONSerializationdataWithJSONObject:requestContents
options:0
error:&error];
if(!requestData){
return;
}
//CreateaPOSTrequestwiththereceiptdata.
NSURL*storeURL=[NSURLURLWithString:@"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=[NSMutableURLRequestrequestWithURL:storeURL];
[storeRequestsetHTTPMethod:@"POST"];
[storeRequestsetHTTPBody:requestData];
//MakeaconnectiontotheiTunesStoreonabackgroundqueue.
NSOperationQueue*queue=[[NSOperationQueuealloc]init];
[NSURLConnectionsendAsynchronousRequest:storeRequestqueue:queue
completionHandler:^(NSURLResponse*response,NSData*data,NSError*connectionError){
if(connectionError){
/*...Handleerror...*/
}else{
NSError*error;
NSDictionary*jsonResponse=[NSJSONSerializationJSONObjectWithData:dataoptions:0error:&error];
if(!jsonResponse){/*...Handleerror...*/}
/*...Sendaresponsebacktothedevice...*/
}
}];

}
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。
