Question

当我尝试在SpriteKit中加载iAd时，场景会重置并重新开始，同时还会运行已经在后台加载的场景。我创建了一个BOOL来帮助确定场景是否已经加载，如果已经加载，那么就不需要再加载它了。 iAd显示正常，但场景本身在屏幕上延伸。这是我的ViewController.m代码：

@implementation ViewController
{
    BOOL _sceneLoaded;
}


- (void)awakeFromNib
{
    [super awakeFromNib];

    [self setCanDisplayBannerAds:YES];
}

- (void)viewWillLayoutSubviews
{
    [super viewWillLayoutSubviews];

    SKView *skView = nil;

    if (self.originalContentView) {
        skView = (SKView *)self.originalContentView;
    }else{
        skView = (SKView *)self.view;
    }

    [skView setShowsDrawCount:NO];
    [skView setShowsFPS:NO];
    [skView setShowsNodeCount:NO];

        if (_sceneLoaded == NO) {
    SKScene *scene = [MainMenuScene sceneWithSize:skView.bounds.size];
    [scene setScaleMode:SKSceneScaleModeFill];
    [skView presentScene:scene];
    _sceneLoaded = YES;
        }
}

我不太确定我哪里出错了。我尝试在代码的不同区域调用if（_sceneLoaded == NO）语句，只是为了达到相同的结果。提前感谢您的帮助。

下面的代码在iOS 7和8中进行了测试，效果很好。

在标题文件

中添加以下行

#import <iAd/iAd.h>

    @interface GameViewController : UIViewController<ADBannerViewDelegate>{

        //iAd
        ADBannerView *adView;

    }

在实施文件.m中添加以下代码

#import "GameViewController.h"
#import "GameScene.h"

@implementation GameViewController

-(void)viewWillLayoutSubviews{

    [super viewWillLayoutSubviews];

    SKView *skView;

    if (self.originalContentView) {

        skView = (SKView *)self.originalContentView;

    }

    if (!skView.scene) {

        //[skView setShowsDrawCount:YES];
        //[skView setShowsFPS:YES];
        //[skView setShowsNodeCount:YES];

        //Improve Performance
        skView.ignoresSiblingOrder = YES;

        GameScene *scene = [GameScene sceneWithSize:skView.bounds.size];
        [scene setScaleMode:SKSceneScaleModeFill];

        [skView presentScene:scene];

    }

}

- (void)awakeFromNib{

    [super awakeFromNib];

    CGRect screenRect = [[UIScreen mainScreen] bounds];

    adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
    adView.frame = CGRectMake(0, 0, screenRect.size.width, adView.frame.size.height);
    adView.delegate=self;
    [self.view addSubview:adView];
}

//iAd
-(void)bannerViewDidLoadAd:(ADBannerView *)banner {

    [adView setAlpha:1.0];
    NSLog(@"Show Ad");

}

-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {

    [adView setAlpha:0];
    NSLog(@"Hide Ad");

}

//

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    } else {
        return UIInterfaceOrientationMaskAll;
    }
}

-(BOOL)prefersStatusBarHidden{

    return YES;

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Release any cached data, images, etc that aren't in use.
}

@end

如果您使用[self setCanDisplayBannerAds：YES]，这会缩小您的视图以为iAd横幅腾出空间。我建议将ADBannerViewDelegate添加到视图控制器并将横幅设置为视图...查看本教程http://codewithchris.com/iad-tutorial/
