应用内购买:删除广告横幅和插页式广告 - 代码帮助
In-App Purchase : Remove Ad Banners & Interstitial Ads - Code Assistance
我有一个简单的单视图应用程序项目 - 一个向用户显示一些随机文本的一 (1) 页应用程序。
我已成功整合广告横幅和插页式广告。
我已经设置了另一个视图控制器 (InAppViewController.swift
) 来处理允许用户进行应用内购买以删除所有广告(广告横幅和插播广告)的弹出页面。
在我的第二个视图控制器 (InAppViewController.swift
) 中,我有以下代码:
修改后的代码:
// InAppPViewController.swift
import UIKit
import StoreKit
import iAd
class InAppPViewController: UIViewController, SKProductsRequestDelegate, SKPaymentTransactionObserver {
let defaults = NSUserDefaults.standardUserDefaults()
var product_id: NSString?;
@IBOutlet weak var unlockAction: UIButton!
@IBOutlet var adBannerView: ADBannerView?
override func viewDidLoad() {
product_id = "holymoly.iap.removeads";
super.viewDidLoad()
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
//Check if product is purchased
if (defaults.boolForKey("purchased")){
self.adBannerView?.hidden = true
}
else if (!defaults.boolForKey("stonerPurchased")){
print("false")
self.adBannerView?.hidden = false
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func unlockAction(sender: AnyObject) {
print("About to fetch the products");
// We check that we are allow to make the purchase.
if (SKPaymentQueue.canMakePayments())
{
let productID:NSSet = NSSet(object: self.product_id!);
let productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>);
productsRequest.delegate = self;
productsRequest.start();
print("Fething Products");
}else{
print("can't make purchases");
}
}
func buyProduct(product: SKProduct){
print("Sending the Payment Request to Apple");
let payment = SKPayment(product: product)
SKPaymentQueue.defaultQueue().addPayment(payment);
}
//Delegate Methods for IAP
func productsRequest (request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
let count : Int = response.products.count
if (count>0) {
let validProduct: SKProduct = response.products[0] as SKProduct
if (validProduct.productIdentifier == self.product_id) {
print(validProduct.localizedTitle)
print(validProduct.localizedDescription)
print(validProduct.price)
buyProduct(validProduct);
} else {
print(validProduct.productIdentifier)
}
} else {
print("nothing")
}
}
func request(request: SKRequest, didFailWithError error: NSError) {
print("Error Fetching product information");
}
func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
print("Received Payment Transaction Response from Apple");
for transaction:AnyObject in transactions {
if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction{
switch trans.transactionState {
case .Purchased:
print("Product Purchased");
SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
defaults.setBool(true , forKey: "purchased")
self.adBannerView?.hidden = true
break;
case .Failed:
print("Purchased Failed");
SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
self.adBannerView?.hidden = false
break;
case .Restored:
print("Already Purchased");
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
default:
self.adBannerView?.hidden = true
break;
}
}
}
}
}
并且在我的 'original' 视图控制器 (ViewController.swift
) 中添加了以下代码:
// ViewController.swift
import UIKit
import MessageUI
import Social
import iAd
class ViewController: UIViewController, MFMailComposeViewControllerDelegate, MFMessageComposeViewControllerDelegate, ADBannerViewDelegate, ADInterstitialAdDelegate
{
var interstitialAd:ADInterstitialAd!
var interstitialAdView: UIView = UIView()
@IBOutlet var adBannerView: ADBannerView?
@IBAction func someFunkyButton(sender: AnyObject) {
//Interstitial Ad:
let rand = Int(arc4random_uniform(4))
print(rand)
let adNo = 2
if(adNo == rand)
{
loadInterstitialAd()
}
}
let defaults = NSUserDefaults.standardUserDefaults()
override func viewDidLoad() {
super.viewDidLoad()
//Check if product is purchased
if (defaults.boolForKey("purchased")){
// Advertising Banner:
self.canDisplayBannerAds = true
self.adBannerView?.delegate = self
self.adBannerView?.hidden = true
}
else if (!defaults.boolForKey("stonerPurchased")){
print("false")
// Advertising Banner:
self.canDisplayBannerAds = true
self.adBannerView?.delegate = self
self.adBannerView?.hidden = false
}
代码显示没有错误。
它在我的实际 iPhone(模拟器)上运行,并且应用内购买有效。
但广告横幅仍然显示。我正在尝试 显示 广告横幅:
(i) 在 ViewController.swift 中:
self.canDisplayBannerAds = true
self.adBannerView?.delegate = self
self.adBannerView?.hidden = false
(ii) InAppViewController.swift:
self.adBannerView?.hidden = false
和不显示广告横幅:
(i) 在 ViewController.swift 中:
self.canDisplayBannerAds = true
self.adBannerView?.delegate = self
self.adBannerView?.hidden = true
(ii) InAppViewController.swift:
self.adBannerView?.hidden = true
但是显然不行。
问题:
如何修改我的代码并停止显示这些广告横幅?
我如何也停止展示我的插页式广告?
我觉得我很接近,非常接近...但是那支雪茄还没有落地!
首先 removeAds
在里面 btnRemoveAds
所以把它移到外面。其次,一种方法是将已购买产品的产品标识符保存在 UserDefaults 中,这样在应用程序退出和启动时,广告将不会出现,因为用户已经购买了 inapp。因此,您将在 viewDidLoad
上做的是检查产品标识符是否已购买(来自 NSUserDefaults
,如果早先购买,则会设置),如果已购买,则从一开始就禁用广告,否则显示广告.购买商品后,在 NSUserDefaults
中设置状态并相应地更新 UI。
如果您要实现自己的 ADBannerView
,则需要删除 self.canDisplayBannerAds = true
。
self.canDisplayBannerAds = true
可用于在您的应用程序中轻松实现 iAd 横幅。这将为您创建一个 ADBannerView
,并根据它是否从 iAd 网络收到广告来显示或隐藏视图底部的 ADBannerView
。
您可以实现自己的 ADBannerView
或使用 self.canDisplayBannerAds = true
,但不能同时使用。
