Classes and Protocols

The most important class is InAppPurchase. All the functions you need are defined in this class.

If you have consumable and/or non-renewing subscription products in your application, you must have a class that adopts the IAPPurchaseDelegate protocol.

Products

• Input: the library requires an array of IAPProduct when it is initialized.

• Output: the library will returns SKProduct extended with helpful methods. See the SKProduct extension.

Callbacks

refresh(), purchase() and restorePurchases() are asynchronous functions. You must provide a callback that will allow you to perform actions depending on the result.

• For refresh() and restorePurchases() functions, the result will be IAPRefreshResult.

• For purchase() function, the result will be IAPPurchaseResult.

Errors

When calling refresh(), purchase() or restorePurchases(), the callback can return an IAPError if the state is failed. Look at IAPErrorCode to see the list of error codes you can receive.
