Question

我正在尝试在我的游戏中实现一个非常简单的iAd，我收到了一个错误。我是Xcode的新手，无法读取错误代码。我在一个新的SpriteKit项目中尝试了完全相同的方法，它运行得很好。我猜这必须与我的游戏有关。

错误如下。

我的ViewController.m如下

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Configure the view.
    SKView * skView = (SKView *)self.view;
    skView.showsFPS = YES;
    skView.showsNodeCount = YES;

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

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

尝试在viewWillLayoutSubViews中添加代码......

- (void)viewWillLayoutSubviews 
{
    [super viewWillLayoutSubviews];
    SKView * skView = (SKView *)self.view;
    skView.showsFPS = YES;
    skView.showsNodeCount = YES;

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

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

显然，我在原始问题中使用的ViewController.m是正确的。造成这个问题的原因是我在AppDelegate.m中放了几行来暂停游戏。这就是我得到'NSInvalidArgumentException'的原因：' - [UIView setPaused：]：error。

以下是我的AppDelegate.m中包含导致崩溃的行的两种方法。

- (void)applicationWillResignActive:(UIApplication *)application
{
    // pause sprite kit
    SKView *view = (SKView *)self.window.rootViewController.view;
    view.paused = YES;

}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    //resume sprite kit
    SKView *view = (SKView *)self.window.rootViewController.view;
    view.paused = NO;
}

我删除了这4行，一切正常。非常感谢那些帮助过的人。
