SBInAppPurchasing
SBInAppPurchasing makes In-App Purchasing easier. Written in Swift.
Features:
- Checking if device is able to make payments
- Requesting list of IAPs
- Making purchases
- Restoring Purchases
- Callbacks and notifications
Note that I haven't done any testing with Consumable IAPs at the current time.
Installation
SBInAppPurchasing is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "SBInAppPurchasing"Usage
####Use the SBInAppPurchasing Singleton:
import SBInAppPurchasing
let purchaser = SBInAppPurchasing.shared####To check if a device can make payments:
Some devices make not be able to make payments, for instance, if not permitted by parental controls. You should always check if the device can make payments before making a purchase
if (purchaser.canMakePayments){
// Make a purchase
}
else{
// Alert user IAPs are disabled
}####To request list of products:
// Products from previous requests are cached.
//Check the products optional if you do not want to refresh
if let products = purchaser.products{
// Products already downloaded
return
}
// The identifiers you set up in iTunes Connect
let identifiers = Set(["com.some.iap", "com.some.other.iap"])
purchaser.requestProducts(identifiers) { (products, error) in
if let error = error{
print("An error occurred: \(error.localizedDescription)")
return
}
if let products = products{
// Array of SKProduct received
}
}####To make a purchase with SKProduct
If you have called requestProducts() already, you can make a purchase using one of the returned products
purchaser.purchase(product: someProduct) {
(success: Bool) in
if success {
// Unlock IAP
}
else{
// Show error
}
}####To make a purchase with identifier
It is also possible to make a purchase without calling requestProducts() by using the product identifier
purchaser.purchase(productWithIdentifier: "com.some.iap") {
(success: Bool) in
if success {
// Unlock IAP
}
else{
// Show error
}
}####To restore Purchases
SBInAppPurchasing.shared.restorePurchases {
(identifer: String) in
if identifer == "com.some.iap" {
// Unlock IAP
}
}####Delegate Callbacks
Using the passed in closures is the easiest way to repond to purchase events, but an object implementing the SBInAppPurchasingDelegate protocol can recieve also receive callbacks for purchasing events, if required.
purchaser.delegate = someObject
// Recieves the following callbacks:
func purchaseCompleted(identifier: String)
func purchaseRestored(identifier: String)
func purchaseFailed(errorDescription: String)####Notifications
Alternatively, objects can listen to notifications via NSNotificationCenter
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(purchaseCompleted), name: .inAppPurchaseCompleted, object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(purchaseRestored), name: .inAppPurchaseRestored, object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(purchaseFailed), name: .inAppPurchaseFailed, object: nil)
func purchaseCompleted(notification: NSNotification){
let identifier = notification.object
}
func purchaseRestored(notification: NSNotification){
let identifier = notification.object
}
func purchaseFailed(notification: NSNotification){
let error = notification.object
