LYIAP

• iOS IAP by Swift 3.0
• Really Really Easy to use

Easy use

Firstly config()

LYIAPHelper.shared.config()

Request products

LYIAPHelper.shared.requestProductsWithIds(NSSet(array: ["PRODUCT_IDENTIFIER"]), completion: {Void in
            // Do something when products have been loaded.
        })

Purchse

LYIAPHelper.shared.purchaseProductWithId(productId: "PRODUCT_IDENTIFIER", completion: {transaction in
            // Identifier of the product that has been purchased
            debugPrint(transaction.payment.productIdentifier)
        })

Restore

LYIAPHelper.shared.restoreWithCompletion(
       success: {transaction in
              // Identifier of the product that has been restored
              // You must add restore function to your app accroding to APPLE's provisions
       			debugPrint(transaction.payment.productIdentifier)
          	},
           finish: {isSucceess in
                // It is called when restore is finished.
                // isSuccess will be true when some products have been restored successfully.
        })

# Basic use - If you want to customize something more to support you App, try to do these below.

Step1

• Conforming to LYIAPDelegate protocol（遵守LYIAPDelegate协议）

	class ViewController: UIViewController, LYIAPDelegate {
		override func viewDidLoad() {
       	super.viewDidLoad()
    	}
	}

Step2

• Set delegate and send product request（设置代理并发送商品请求）

	 override func viewDidLoad() {
        super.viewDidLoad()
        LYIAP.setRequestWithProducts(NSSet(array: ["PRODUCT_IDENTIFIER"]), delegate: self)
        LYIAP.startRequest()
    }

Step3

• Implement delegate function（实现代理方法）

    func requestFinished() {
        // Do something when products have been loaded.
    }

    func transactionPurchased(_ queue: SKPaymentQueue, transaction: SKPaymentTransaction) {
        // Identifier of the product that has been purchased
        debugPrint(transaction.payment.productIdentifier)
        
        LYIAP.verifyPruchase(completion: {(receipt,error) in
            // You can verify the transaction. 
            // In this callback, you will get the receipt if the transaction is verified by the APPLE. 
            // You can compare some tranction infomation with the receipt.
            debugPrint(receipt)
        })
    }
    
    func transactionRestore(_ queue: SKPaymentQueue, transaction: SKPaymentTransaction) {
        // Identifier of the product that has been restored
        // You must add restore function to your app accroding to APPLE's provisions
        debugPrint(transaction.payment.productIdentifier)
    }
