我正在使用这段代码进行应用内购买,它来自RaywernderLich的教程。
// Encode the receiptData for the itms receipt verification POST request.
NSString *jsonObjectString = [self encodeBase64:(uint8_t *)transaction.transactionReceipt.bytes
length:transaction.transactionReceipt.length];
现在Xcode提示:
'transactionReceipt' 已弃用:自iOS 7.0起首次弃用
如何修复?
