Invalid transaction receipt returned by appStoreReceiptURL (NSData), in iOS 7

Question

I\'m using following method to get the receipt data:

// Use this method instead of accessing transaction.transactionReceipt directly!
- (NSData *)appStoreRec         


        

Answer 1

iOS 7 has changed how receipt validation is done. I went through the exact path you're down and got the same results. What I found was that the receipt from [[NSBundle mainBundle] appStoreReceiptURL] requires a different method for decoding than the previous transaction.transactionReceipt.

Here is a snippet from Apple's docs:

The outermost portion is a PKCS #7 container, as defined by RFC 2315, with its payload encoded using ASN.1 (Abstract Syntax Notation One), as defined by ITU-T X.690. The payload is composed of a set of receipt attributes. Each receipt attribute contains a type, a version, and a value.
