ios - SpriteKit 中的 AdMob 插页式广告

Question

我之前曾使用 AdMob 展示横幅广告，并且在这个项目中发挥了作用。
现在我不会在游戏结束后显示 AdMob 广告。
这是用 SpriteKit 编写的游戏。

游戏失败后在我的 GameScene 中:

GameOverScene* gameOverScene = [[GameOverScene alloc] initWithSize:self.frame.size playerScore:_topPoints playerTime:elapsedTime];
SKTransition *transition = [SKTransition fadeWithDuration:2.5];
[self.view presentScene:gameOverScene transition:transition];

这工作正常。

在 GameOverScene.m 中我有:

@interface GameOverScene ()
@property(nonatomic, strong) GADInterstitial *interstitial; // for Ads
@end

@implementation GameOverScene

-(id)initWithSize:(CGSize)size playerScore:(NSUInteger)score playerTime:(CFTimeInterval)elapsedTime;
{
    self = [super initWithSize:size];

    if (self)
    {
        // code for hight score just text label, not important

        // for adds
        [self performSelector:@selector(showBanner) withObject:nil afterDelay:1.5];
    }

    return self;
}

- (void) showBanner
{
    self.interstitial = [[GADInterstitial alloc] init];
    self.interstitial.adUnitID = @"ca-app-pub-3940256099942544/4411468910";

    GADRequest *request = [GADRequest request];
    // Requests test ads on simulators.
    request.testDevices = @[ GAD_SIMULATOR_ID ];
    [self.interstitial loadRequest:request];

    [self performSelector:@selector(showBanner1) withObject:nil afterDelay:1.5];
}

- (void) showBanner1
{
    if ([self.interstitial isReady])
    {
        NSLog(@"EEEEEEEEEEEEEEEEE");

        [self.interstitial presentFromRootViewController:(UIViewController *)self];
    }
    else
    {
        NSLog(@"NO NO NO NO AD");
        [self.interstitial presentFromRootViewController:self];
    }
}

这段代码正在执行，但我有以下问题:

[self.interstitial presentFromRootViewController:(UIViewController *)self];

是否运行时错误:

-[GameOverScene presentViewController:animated:completion:]: unrecognized selector sent to instance 0x7fee8b8ceb80

据我所知，我认为存在一些问题，因为 self.interstitial presentFromRootViewController: 需要 RootViewController 但我的 GameOverScene 是 SKScene。

问题
如何在 SKScene 中显示 AdMob 插页式广告？

Answer 1

您的 GameOverScene 不是 UIViewController。这样做。

@interface AppDelegate 
{
    ViewController *viewController;
} 
@property (strong, nonatomic) ViewController *viewController;

在 ViewController.m 中赋值。

@implementation ViewController

- (void)viewWillLayoutSubviews
{
     AppDelegate *app = ((AppDelegate *)[[UIApplication sharedApplication] delegate])
     app.viewController = self;
}

//在任何地方

-(void)SetupAdmob  //call only first time
{
       mInterstitial_ = [[GADInterstitial alloc] init];
    mInterstitial_.adUnitID = ADMOB_FULL_SCREEM;
    [mInterstitial_ loadRequest:[GADRequest request]];

    [self performSelector:@selector(showAdmobInterstitial) withObject:nil afterDelay:1.5];
}

-(void)showAdmobInterstitial  //call this to show fullScreen ads
{
    AppDelegate *app = ((AppDelegate *)[[UIApplication sharedApplication] delegate])

    [mInterstitial_ presentFromRootViewController: app.viewController];

    mInterstitial_ = nil;

    mInterstitial_ = [[GADInterstitial alloc] init]; //Cache new ads for next time
    mInterstitial_.adUnitID = ADMOB_FULL_SCREEM;
    [mInterstitial_ loadRequest:[GADRequest request]];

}
