应用程序内购买 – 如何在Swift中使用Xcode 7和SpriteKit修复iOS

我已经为Xcode 7.0,iOS 9.0和Swift 2.0添加了我的默认IAP,使用正确的字符串更改“com.dname.YourApp.removeAds”:)

//  IAPViewController.swift

import UIKit
import StoreKit

class IAPViewController: UIViewController,SKProductsRequestDelegate,SKPaymentTransactionObserver{

    let userDefaults = NSUserDefaults.standardUserDefaults()

    //@IBOutlet var lblAd: UILabel!
   // @IBOutlet var lblCoinAmount: UILabel!

    @IBOutlet var removeAds: UIButton!
    //@IBOutlet var outAddCoins: UIButton!
    //var coins = 50

    // 1
    override func viewDidLoad() {
        super.viewDidLoad()
        removeAds.enabled = false
       // outAddCoins.enabled = false

        // Set IAPS
        if(SKPaymentQueue.canMakePayments()) {
            print("IAP is enabled,loading")
            let productID:NSSet = NSSet(objects: "com.dname.YourApp.removeAds")
            let request: SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>)
            request.delegate = self
            request.start()
        } else {
            print("please enable IAPS")
        }

    }

    // 2
    @IBAction func btnRemoveAds(sender: UIButton) {
        for product in list {
            let prodID = product.productIdentifier
            if(prodID == "com.dname.YourApp.removeAds") {
                p = product
                buyProduct()
                break;
            }
        }

    }
