ios - 应用关闭后如何在应用购买中保留删除广告

Question

我已通过应用内购买成功地从应用中删除了广告。

问题是，如果我关闭应用程序并重新打开。广告再次开始。

我有两个主要场景。 GameOverScene 和 GameScene。应用内购买发生在 GameOverScene 中。

GameOverScene.m :

- (void)OnRemoveADS {
    [self showPurchaseAlert: IAP_Q_RemoveADS  :0];

    g_bRemoveADS = [[NSUserDefaults standardUserDefaults] boolForKey: @"REMOVEADS"];

    // For HZInterstitialAd, HZVideoAd, and HZIncentivizedAd, just check the BOOL to see if an ad should be shown
    if (!g_bRemoveADS) {
        [HZInterstitialAd show];

        [self removeBannerAds];
        [self disableAds];
        NSLog(@"Disable ads is called");
    }
}

- (void)removeBannerAds {
    HZBannerAdOptions *options = [[HZBannerAdOptions alloc] init];

    [HZBannerAd placeBannerInView:self.view
                         position:HZBannerPositionBottom
                          options:options
                          success:^(HZBannerAd *banner) {
                              if (g_bRemoveADS) { // case (2)
                                  // Just discard the banner
                                  [banner setHidden: YES];
                                  [banner removeFromSuperview];
                                  banner = nil;

                                  //_currentBannerAd = banner;

                                  NSLog(@"Banner ad removed!GameOverScene");
                              } else {
                                  // Keep a reference to the current banner ad, so we can remove it from screen later if we want to disable ads.
                                  _currentBannerAd = banner;
                              }
                              NSLog(@"Ad Shown! GameOverScene");
                          } 
                          failure:^(NSError *error) {
                              NSLog(@"Error = %@",error);
                          }];
}

- (void)disableAds {
    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"REMOVEADS"];
    [_currentBannerAd removeFromSuperview]; // case (3)
}

游戏场景.m:

-(id) init {
    if (self = [super init]) {
        if (!g_bRemoveADS) {
            g_bRemoveADS=FALSE;
            [[NSUserDefaults standardUserDefaults] setBool:g_bRemoveADS forKey:@"REMOVEADS"];
            [[NSUserDefaults standardUserDefaults] synchronize];
        } else {
            g_bRemoveADS=TRUE;
            [[NSUserDefaults standardUserDefaults] setBool:g_bRemoveADS forKey:@"REMOVEADS"];
            [[NSUserDefaults standardUserDefaults] synchronize];
        }
    }
}

我尝试解决它的方法是在 AppDelegate.m 中使用来自 GameOverScene.m 的相同代码，这样当应用程序启动时它会删除广告。

AppDelegate.m :

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    g_bRemoveADS = [[NSUserDefaults standardUserDefaults] boolForKey: @"REMOVEADS"];

    if (!g_bRemoveADS) {

        [HZInterstitialAd show];

        [self disableAds];
        NSLog(@"Disable ads is called");
    }
}

Answer 1

从我的角度来看，你有一个否定。

if (!g_bRemoveADS) { 在 GameOverScene.m 中应替换为 if (g_bRemoveADS) {。

if (g_bRemoveADS) {
    [HZInterstitialAd show];

    [self removeBannerAds];
    [self disableAds];
    NSLog(@"Disable ads is called");
}

g_bRemoveADS 在设置相应的用户默认值时评估为 TRUE。设置后，您将调用 removeBannerAds 之类的东西，这似乎是停用操作。
