ios - AdMob Interstitial 每五场比赛一次

Question

我在我的项目中实现了 AdMob Interstitial 广告，效果很好。现在我希望 AdMob Interstitial 广告只在每五场比赛中出现一次，而不是在每场比赛之后出现。有人可以帮助我吗？

这是我的 GameViewController 中的 Admob 代码:

- (void)viewDidLoad {
[super viewDidLoad];

    //addInterstitial
    self.interstitial = [[GADInterstitial alloc] initWithAdUnitID:@"ca-app-pub-XXXXXXXXXX/XXXXXXXXXX"];

    GADRequest *request = [GADRequest request];
    request.testDevices = @[@"XXXXXXXXXXXXXXXXXXXXXXXXXX"];
    [self.interstitial loadRequest:request];

    [[NSNotificationCenter defaultCenter]addObserver:self 

    selector:@selector(handleNotification:) name:@"showAd" object:nil]; }



    - (void)handleNotification:(NSNotification *)notification
    {
        if ([notification.name isEqualToString:@"showAd"]) {
            if ([self.interstitial isReady]) {
                [self.interstitial presentFromRootViewController:self]; }

更新:

我在 GameViewController 中有这段代码:

- (void)viewDidLoad {
    [super viewDidLoad];

    //addInterstitial
    if ([[NSUserDefaults standardUserDefaults] objectForKey:GAME_AMOUNT_KEY] == nil){
        NSNumber *number = [NSNumber numberWithInt:0];
        [[NSUserDefaults standardUserDefaults] setObject: number forKey: GAME_AMOUNT_KEY];
        [[NSUserDefaults standardUserDefaults] synchronize];

    }

    if ([[[NSUserDefaults standardUserDefaults] objectForKey:GAME_AMOUNT_KEY] intValue] >= 5){
        [self callAd];
        self.interstitial = [self createAndLoadInterstitial];

        NSNumber *number = [NSNumber numberWithInt:0];
        [[NSUserDefaults standardUserDefaults] setObject: number forKey: GAME_AMOUNT_KEY];
        [[NSUserDefaults standardUserDefaults] synchronize];
    }
- (void)handleNotification:(NSNotification *)notification {
    if ([notification.name isEqualToString:@"showAd"]) {
        if ([self.interstitial isReady]) {
            [self.interstitial presentFromRootViewController:self];
        }
    }
}

- (void) callAd{

    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(handleNotification:) name:@"showAd" object:nil];
}


- (GADInterstitial *)createAndLoadInterstitial {
    self.interstitial = [[GADInterstitial alloc] initWithAdUnitID:MyAdUnitID2];
    self.interstitial.delegate = self;
    GADRequest *request2 = [GADRequest request];
    request2.testDevices = @[@"XXXXXXXXXXXXXXXXXXXXXX"];
    [self.interstitial loadRequest:request2];
    return self.interstitial;
}

- (void)interstitialDidDismissScreen:(GADInterstitial *)interstitial {
    self.interstitial = [self createAndLoadInterstitial];
}

在 GameScene.m 中，这段代码:

    - (void)showGameOver{

        //addInterstitial
        int score = [[[NSUserDefaults standardUserDefaults] objectForKey:GAME_AMOUNT_KEY] intValue]+1;
            NSNumber *newNumber = [NSNumber numberWithInt:score];
        [[NSUserDefaults standardUserDefaults] setObject:newNumber forKey:GAME_AMOUNT_KEY];
        [[NSUserDefaults standardUserDefaults] synchronize];

        [[NSNotificationCenter defaultCenter] postNotificationName:@"showAd" object:nil];

使用 NSUserDefaults:

- (void) callAd
{
  // Code to call your ad here
}

- (void) viewDidLoad
{
// If you haven't played yet, sets to 0

  if ([[NSUserdefaults standardUserDefaults] objectForKey:GAME_AMOUNT_KEY] == nil){
    NSNumber *num = [NSNumber numberWithInt:0];
    [[NSUserDefaults standardUserDefaults] setObject: num forKey: GAME_AMOUNT_KEY];
    [[NSUserDefaults standardUserDefaults] synchronize];

  }

// If you have played

  if ([[[NSUserdefaults standardUserDefaults] objectForKey:GAME_AMOUNT_KEY] intValue] >= 5){
     [self callAd];  // ad is called


   NSNumber *num = [NSNumber numberWithInt:0];
        [[NSUserDefaults standardUserDefaults] setObject: num forKey: GAME_AMOUNT_KEY];
        [[NSUserDefaults standardUserDefaults] synchronize]; // resets to zero
  }
}

每当游戏结束时:

int score = [[[NSUserdefaults standardUserDefaults] objectForKey:GAME_AMOUNT_KEY] intValue] 
+ 1;
NSNumber *newNumber = [NSNumber numberWithInt:score];
[[NSUserDefaults standardUserDefaults] setObject:newNumber forKey: GAME_AMOUNT_KEY];
[[NSUserDefaults standardUserDefaults] synchronize]; // Sets to new value

key 实际上可以是任何东西。在 .m 文件的顶部放置:

#define GAME_AMOUNT_KEY @"Game Amount Key"

改变:

- (void)handleNotification:(NSNotification *)notification
    {
        if ([notification.name isEqualToString:@"showAd"]) {
            if ([self.interstitial isReady]) {
                [self.interstitial presentFromRootViewController:self]; 
}

收件人:

- (void)handleNotification:(NSNotification *)notification
    {
        if ([notification.name isEqualToString:@"showAd"]) {
            if ([self.interstitial isReady]) {


    if ([[[NSUserDefaults standardUserDefaults] objectForKey:GAME_AMOUNT_KEY] intValue] >= 5){
                    [self.interstitial presentFromRootViewController:self]; 

                NSNumber *number = [NSNumber numberWithInt:0];
                [[NSUserDefaults standardUserDefaults] setObject: number forKey: GAME_AMOUNT_KEY];
                [[NSUserDefaults standardUserDefaults] synchronize];
            }

    }

并更改(在 ViewDidLoad 中):

if ([[[NSUserDefaults standardUserDefaults] objectForKey:GAME_AMOUNT_KEY] intValue] >= 5){
        [self callAd];
        self.interstitial = [self createAndLoadInterstitial];

        NSNumber *number = [NSNumber numberWithInt:0];
        [[NSUserDefaults standardUserDefaults] setObject: number forKey: GAME_AMOUNT_KEY];
        [[NSUserDefaults standardUserDefaults] synchronize];
    }

到

        [self callAd];
        self.interstitial = [self createAndLoadInterstitial];
