如何通过应用内购买删除广告？ [英] How do I remove ads with In-App Purchase?

问题描述

我无法找到购买后我的iAd未被删除的原因。

I am having trouble finding out why my iAd is not being removed after a purchase.

以下是我在iAd文件中尝试的内容：

Here is what I am trying in the file that has the iAd:

#define kInAppPurchaseUpgradeProductId @"kInAppPurchaseUpgradeProductId"

NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
BOOL adsAreOff = [defaults boolForKey:kInAppPurchaseUpgradeProductId];

if (!adsAreOff)
{
    adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
    adView.frame = CGRectOffset(adView.frame, 0, -50);
    adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifierPortrait];
    adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
    CGRect adFrame = adView.frame;
    adFrame.origin.y = self.view.frame.size.height-adView.frame.size.height;
    adView.frame = adFrame;
    adView.backgroundColor = [UIColor clearColor];
    [self.view addSubview:adView];
    adView.delegate=self;
    self.bannerIsVisible=NO;
}
else 
{
    [adView removeFromSuperview];
}

以下是我在应用内购买代码中尝试的内容：

Here is what I am trying in my In-App Purchase code:

-(void)purchaseUpgrade
{
    SKPayment * payment = [SKPayment paymentWithProductIdentifier:kInAppPurchaseUpgradeProductId];
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

-(IBAction)purchaseButtonTapped
{
    NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:adView forKey:kInAppPurchaseUpgradeProductId];

    // I tried this first, didn't work
    //[defaults setBool:TRUE forKey:kInAppPurchaseUpgradeProductId];

    [defaults synchronize];

    [self purchaseUpgrade];
}

这是在正确的地方处理，还是应该在 paymentQueue 方法？

Is this handled in the right place, or should it be in the paymentQueue method?

推荐答案

确保您正在同步 NSUserDefaults 在购买应用程序后设置密钥时：

Make sure that you're synchronizing your NSUserDefaults when you set the key after the application is purchased:

// After a purchase is made:
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:SOMETHING forKey:kInAppPurchaseUpgradeProductId]
[defaults synchronize];
