Purpose

FMPurchaseManager is a wrapper on the StoreKit framework that makes the whole purchase process easier.

*NOTE: the supported build target is iOS 5.1 (Xcode 4.4)

Installation

Add the <StoreKit/StoreKit.h> framework and drag the FMPurchaseManager class files into your project.

Usage

(see sample Xcode project /Demo)

First of all you must setup the two blocks that are called during the purchase process.

1. Handle the product request completion

   [FMPurchaseManager setProductRequestCompletion:
   ^(NSArray *products, NSArray *invalidProductIdentifiers) {
   	//you receive an array of SKProduct objects
   	//and a list of invalid product identifiers
   }];

2. Handle the purchase completion

   [FMPurchaseManager setProductPurchaseCompletion:
   ^(SKPaymentTransaction *transaction, NSString *productIdentifier, NSError *error) {
   	if (error == nil)
   	{
   		//the purchase has completed, do whatever you want with the transaction
   	}
   	else
   	{
   		//something went wrong with your purchase or the user cancelled it
   	}
   }];

Once you prepared the completion blocks you can:

• request the products with the related identifiers [FMPurchaseManager requestProducts:someProducts]
• buy a product with its identifier [FMPurchaseManager buyProduct:anIdentifier]
• restore the previously purchased products [FMPurchaseManager restorePurchases]
