Validating Receipts With the App Store

// Load the receipt from the app bundle.
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
if (!receipt) { /* No local receipt -- handle the error. */ }

/* ... Send the receipt data to your server ... */

Apple Developer

For an application purchased from the App Store, use this application bundle property to locate the receipt. This property makes no guarantee about whether there is a file at the URL—only that if a receipt is present, that is its location.
