Question

处理我的第一款游戏并尝试在其中实施广告。

我在viewController.h中声明了以下内容

#import <UIKit/UIKit.h>
#import <SpriteKit/SpriteKit.h>
#import <iAd/iAd.h>

@interface ViewController : UIViewController <ADBannerViewDelegate>

在我的实现文件中，我得到了以下内容（因为我需要横向布局而使用）

- (void)viewWillLayoutSubviews
{


        [[NSUserDefaults standardUserDefaults] setInteger:0 forKey:@"Result"];
    [super viewWillLayoutSubviews];
    NSError *error;
    NSURL * backgroundMusicURL = [[NSBundle mainBundle] URLForResource:@"background-music-aac" withExtension:@"caf"];
    self.backgroundMusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:&error];
    self.backgroundMusicPlayer.numberOfLoops = -1;
    [self.backgroundMusicPlayer prepareToPlay];
    [self.backgroundMusicPlayer play];

    // Configure the view.

    SKView * skView = (SKView *)self.view;
    if (!skView.scene) {
      skView.showsFPS = YES;
      skView.showsNodeCount = YES;

      // Create and configure the scene.
      SKScene * scene = [MyScene sceneWithSize:skView.bounds.size];
      scene.scaleMode = SKSceneScaleModeAspectFill;

      // Present the scene.
      [skView presentScene:scene];
        self.canDisplayBannerAds = YES;

    }
}

然而，当我运行应用程序立即崩溃（记录下面） - 如果我改变self.canDisplayBannerAdds = NO;该应用程序运行正常 - 我有一种感觉这是非常简单但我看不到它 - 任何人都有任何想法？

当canDisplayBannerAdds设置为YES时，您需要使用控制器上的originalContentView来抓住您的视图。

尝试使用以下代码来掌握您的观点：

SKView * skView = self.originalContentView;

canDisplayBannerAds = YES导致Sprite Kit应用程序崩溃
