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:requestContents
options:0
error:&error];
if (!requestData) {
return;
}
// Create a POST request with the receipt data.
NSURL *storeURL = [NSURL URLWithString:@"https://www.easck.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:queue
completionHandler:^(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 ... */
}
}];
