I am rewriting the code I use to validate App Store receipts to use ComonCrypto instead of openssl. In my project is a folder named _MASReceipt with an example receipt that I got from Apple, called receipt. When I call the NSURL method[code]NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];[/code]I get a URL that appears to be correct: Contents/_MASReceipt/receipt.But when I use the URL to open the receipt, for example:[code]NSError *theError;NSData *receiptData = [NSData dataWithContentsOfURL: receiptURL options: NSDataReadingMappedAlways error: &theError];[/code]The NSData pointer is nil and the NSError contains this error:domain: @NSCocoaErrorDomain Code: - 260Code 260 is a file not found error.Why cant the URL I get from the mail bundle be used to open the file?
