Hi，I am facing the 21002 issue.Have you went through it? If you have resolved it, please dive me a hand.
Below is my code,and I Have tested in sand box environment.
NSURL receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
if (![[NSFileManager defaultManager] fileExistsAtPath:[receiptURL path]]) {
SKReceiptRefreshRequest receiptRefreshRequest = [[SKReceiptRefreshRequest alloc] initWithReceiptProperties:nil];
receiptRefreshRequest.delegate = self;
[receiptRefreshRequest start];
return;
}
NSData data = [NSData dataWithContentsOfURL:receiptURL];
/ receipt_data/
NSString *receipt_data = [data base64EncodedStringWithOptions:0];
After I test the purchase procedure, use the above receipt-data to verify on the server https://sandbox.itunes.apple.com/verifyReceipt,which always response 21002.I have no idea to deal with it.Thanks.
