iAd Banner implementation on Game Over Class - ios

Question

So I have a game that has a game over class. I also have an iAd banner at the bottom of the screen, but it stays there for the entire length of the game. I want the banner to appear when the game ends, and disappear when the user presses the restart game button.
In my RootViewController.mm I have the following code
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
ADBannerView *adView = [[ADBannerView alloc] initWithFrame: CGRectMake(0,self.view.frame.size.height - 50, 320, 50)];
[self.view addSubview:adView];
}
How would I go about only displaying an iAd banner when the game ends?

Answer 1

You should create a Shared iAd Banner in your AppDelegate and then present the ADBannerView on which ever ViewController you like. This implementation takes into account that an ADBannerView will not always receive an ad from the iAd network. The ADBannerView's alpha property is set depending on whether it receives an ad or not using the ADBannerView's delegate methods. This way, you can just display and hide the ADBannerView when the game ends and when you reset it knowing that the ADBannerView will only be visible if it has an ad to present.
AppDelegate.h
#import <UIKit/UIKit.h>
#import iAd; // Import iAd
#interface AppDelegate : UIResponder <UIApplicationDelegate, ADBannerViewDelegate> // Include delegate
#property (strong, nonatomic) UIWindow *window;
#property (strong, nonatomic) ADBannerView *adView;
AppDelegate.m
#import "AppDelegate.h"
#interface AppDelegate ()
#end
#implementation AppDelegate
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Create our one ADBannerView
_adView = [[ADBannerView alloc]init];
// Set delegate and hide banner initially
_adView.delegate = self;
_adView.hidden = YES;
return YES;
}
// iAd delegate methods
-(void)bannerViewDidLoadAd:(ADBannerView *)banner {
NSLog(#"bannerViewDidLoadAd");
_adView.alpha = 1.0;
}
-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
NSLog(#"didFailToReceiveAdWithError: %#",error);
_adView.alpha = 0.0;
}
ViewController.m
#import "ViewController.h"
#import "AppDelegate.h"
#interface ViewController () {
AppDelegate *appDelegate;
}
#end
#implementation ViewController
-(void)viewDidLoad {
[super viewDidLoad];
// Create reference to our app delegate
appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
// Position
appDelegate.adView.center = CGPointMake(self.view.center.x,
self.view.frame.size.height - appDelegate.adView.frame.size.height / 2);
// Add to view
[self.view addSubview:appDelegate.adView];
// I'm just calling the gameOver function for example
// You should add the contents of the function to something more suitable
[self gameOver];
}
-(void)gameOver {
// Unhide the ADBannerView in which ever function is called first in the gameover view
// I'm guessing you have a UIButton that this would work in
appDelegate.adView.hidden = NO;
}
-(void)gameReset {
// When you reset the game hide the ADBannerView
// I'm guessing you have a UIButton that this would work in also
appDelegate.adView.hidden = YES;
}

Answer 2

You can try this bit of code:
When your game ends: [self showiAdBanner];
When your game begins: [self hideiAdBanner];
If you use this code, you'll want to replace this:
ADBannerView *adView = [[ADBannerView alloc] initWithFrame: CGRectMake(0,self.view.frame.size.height - 50, 320, 50)];
[self.view addSubview:adView];
with this:
[self showiAdBanner];
Two methods to show iad and hide iad:
- (void)showiAdBanner {
if( !_adView ) { // only add to view if it's not already there
_adView = [[ADBannerView alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height - 50, 320, 50)]; //initialize it
_adView.delegate = self; // set delegate
}
_adView.hidden = NO; //reveal it
_bannerIsVisible = YES; //set bool to yes
}
- (void)hideiAdBanner {
_adView.hidden = YES; //hide it
_bannerIsVisible = NO; // set bool to no
}
Remember to add this part as well:
#interface RootViewController () <ADBannerViewDelegate>
#property (nonatomic, strong) ADBannerView *adView;
#property (nonatomic) BOOL bannerIsVisible;
#end
If you want to get fancy, instead of hiding it, you can animate/fade it out.
