ios - 如何在 Objective c 中隐藏谷歌广告

Question

在我的项目中，我实现了 Google-Mobile-Ads SDK。我已经按照谷歌网站上写的所有步骤进行操作。我可以在我的所有 View Controller 中访问谷歌广告，因为我已经在我的 AppDelegate 中对其进行了编码。

现在，我想让它从第一个 View Controller 中隐藏它(就像我们可以隐藏导航栏一样)，如何实现它？

在 AppDelegate 的 DidFinishLaunchingMethod 中为谷歌广告编码:-

 bannerView=[[GADBannerView alloc] initWithFrame:CGRectMake(0, self.window.frame.size.height-50, self.window.frame.size.width, 50)];
[self.window addSubview:bannerView];

bannerView.adUnitID = @"ca-app-pub-8809802355107737/4999307809";
bannerView.rootViewController = self.window.rootViewController;
bannerView.delegate=self;
GADRequest *request = [GADRequest request];
request.testDevices = @[ @"eba07768136b615eee7c1f8acde25c1b",kGADSimulatorID ];
[bannerView loadRequest:request];

[self.window makeKeyAndVisible];

return YES;

---

我在 appDelegate 类中也有这个方法:-

 - (void)adViewDidReceiveAd:(GADBannerView *)view;
  {
  if (container.view.frame.size.height==self.window.frame.size.height-50) {

   }
else
{
CGRect navFrame = container.view.frame;
navFrame.size.height -= 50;
container.view.frame = navFrame;
}
NSLog(@"asdhaskda");
  }

在 firstViewController 中:

-(void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    [[NSNotificationCenter defaultCenter] postNotificationName:@"HIDEBANNER" object:nil];
}

-(void)viewDidDisappear:(BOOL)animated{
    [super viewDidDisappear:animated];
    [[NSNotificationCenter defaultCenter] postNotificationName:@"SHOWBANNER" object:nil];
}

在 AppDelegate.m 文件中，在 didFinishLaunchingWithOptions 中:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(hideBanner) name:@"HIDEBANNER" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(showBanner) name:@"SHOWBANNER" object:nil];

同时实现这两个功能。我不确定这些功能中到底必须包含什么。也许是这样的:

 -(void)showBanner{
    [bannerView setHidden:NO];
    //this is from your code
if (container.view.frame.size.height==self.window.frame.size.height-50) {

   }
else
{
CGRect navFrame = container.view.frame;
navFrame.size.height -= 50;
container.view.frame = navFrame;
}
}

-(void)hideBanner{
    [bannerView setHidden:YES];
    CGRect navFrame = container.view.frame;
    navFrame.size.height = self.window.frame.size.height;
    container.view.frame = navFrame;
}
