Purchase

[[IAPShare sharedHelper].iap buyProduct:product
                                    onCompletion:^(SKPaymentTransaction* trans){
}];

Check Receipt with shared secret

For checking receipt , recommend to use only for server side. I am not recommend to use from client side directly check it. However, sometime we want to use only on client side for some reason. Use with your own risk.

Please check Apple guide .

[[IAPShare sharedHelper].iap checkReceipt:[NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]] AndSharedSecret:@"your sharesecret" onCompletion:^(NSString *response, NSError *error) {

}];

Check Receipt without shared secret

Please check Apple guide .

[[IAPShare sharedHelper].iap checkReceipt:[NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]] onCompletion:^(NSString *response, NSError *error) {

}];

Saving Product Identifier

[[IAPShare sharedHelper].iap provideContentWithTransaction:transaction];

Check for Previous Purchase

if([[IAPShare sharedHelper].iap isPurchasedProductsIdentifier:@"com.comquas.iap.test"]
	{
		// require saving product identifier first
	}

Purchased Products

NSLog(@"%@",[IAPShare sharedHelper].iap.purchasedProducts);

Clear Purchases

[[IAPShare sharedHelper].iap clearSavedPurchasedProducts];
[[IAPShare sharedHelper].iap clearSavedPurchasedProductByID:@"com.myproduct.id"];

Restore Purchase

[[IAPShare sharedHelper].iap restoreProductsWithCompletion:^(SKPaymentQueue *payment, NSError *error) {

		//check with SKPaymentQueue

		// number of restore count
		int numberOfTransactions = payment.transactions.count;

		for (SKPaymentTransaction *transaction in payment.transactions)
		{
            NSString *purchased = transaction.payment.productIdentifier;
	        if([purchased isEqualToString:@"com.myproductType.product"])
        	{
				//enable the prodcut here
	        }
    	}

}];
