How to hide google ads in Objective c - ios

Question

In my project , i have implemented Google-Mobile-Ads SDK. I have followed all the steps with are written in the google site. I am able to access the google ad in all my view controllers as i have coded it in my AppDelegate.
Now , i want it to hide it from the first view controller (like we can hide navigationbar), how to implement this ?
In have coded this for google ads in AppDelegate`s DidFinishLaunchingMethod:-
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;
I have this method also in appDelegate class :-
- (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");
}

in firstViewController:
-(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];
}
In AppDelegate.m file, in didFinishLaunchingWithOptions:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(hideBanner) name:#"HIDEBANNER" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(showBanner) name:#"SHOWBANNER" object:nil];
Also implement those 2 functions. I'm not sure what exactly must be in those functions. Maybe something like this:
-(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;
}

There are many methods to do that. You can use, for example, NSNotificationCenter.
In your AppDelegate.m file in didFinishLaunchingWithOptions function:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(hideBanner) name:#"HIDEBANNER" object:nil];
Also in AppDelegate.m add the following function:
-(void)hideBanner{
[bannerView setHidden:YES];
}
And somewhere in you project, when you need to hide banner just call this:
[[NSNotificationCenter defaultCenter] postNotificationName:#"HIDEBANNER" object:nil];

AdMob Integration Full Code.
AppDelegate.h
// Write This Code in AppDelegate.h File Start
#import GoogleMobileAds;
#pragma mark - Admob
#property (strong, nonatomic) GADBannerView *bannerView;
-(void)loadAdmob:(UIViewController *)vc;
// End
AppDelegate.m
// Write This Code in AppDelegate.m File Start
#pragma mark - Admob Methods
-(void)loadAdmob:(UIViewController *)vc{
self.bannerView = [[GADBannerView alloc] initWithFrame:CGRectMake(0, vc.view.frame.size.height-kBannerHeight, vc.view.frame.size.width, kBannerHeight)];
[vc.view addSubview:self.bannerView];
self.bannerView.hidden = YES;
//### Load Banner Ad view #####
// Replace this ad unit ID with your own ad unit ID.
self.bannerView.adUnitID = #"ca-app-pub-####"; // Botttom banner
self.bannerView.rootViewController = vc;
GADRequest *request = [GADRequest request];
// Requests test ads on devices you specify. Your test device ID is printed to the console when
// an ad request is made.
#ifdef DEBUG
request.testDevices = #[kGADSimulatorID];
//[Note: Comment this line for release build]
#endif
[self.bannerView loadRequest:request];
}
// Add this code in Viewcontroller.m file
[APP_DELEGATE loadAdmob:self];
// Add this line in PrefixHeader.pch
#define APP_DELEGATE (AppDelegate*)[[UIApplication sharedApplication] delegate]
#define kBannerHeight (IS_IPAD ? 65.0 : 49.0)
