Cocoa touch IAD仍然拒绝工作

编辑：这是我的AppDelegate（它的一部分）

我就要放弃了。就在过去的几天里，我尝试了5种不同的方法，让一个iAd准确地显示出来，就像苹果公司所说的那样简单，几乎100%的时间我要么没有看到广告，要么出现错误。我严格遵循了苹果的文档。

我唯一的线索就是这两行

    GameViewController *gameViewController = [[GameViewController alloc]init];
    NSLog(@"NSLOG %@", [[gameViewController view]class]);

在我的应用程序代理中。NSLog为我提供了“UIView”。不，为什么？为什么它会是UIView，它应该是SKView，因为GameViewController是apple为sprite工具包为我预先编写的。那怎么可能给我错误的目标呢

我收到了

'NSInvalidArgumentException'，原因：'-[UIView场景]：未识别的选择器发送到实例0x174191780'

，其他人建议通过放入

原始内容

语句来修复该选择器，但我已经有了它，并且它不起作用

横幅视图控制器：

我想出来了。答案，正如我所想的那样，是难以置信的简单和令人难以置信的，苹果公司不会在他们的文档中添加某种警告，但是再一次，也许我只是一个过犹不及的人，我们应该知道这类事情

答案是，

init

从未在

GameViewController

中调用，而是调用了

initWithCoder:

。一旦我记录了

init

方法，发现它没有被调用，我就明白了这一点

@interface GameViewController ()
@property (nonatomic, strong) IBOutlet UIView *contentView;

@end

@implementation GameViewController {

}
-(instancetype)init{
    self = [super init];
    if (self) {

    }
    return self;
}
-(void)viewDidLoad{
    //self.canDisplayBannerAds = YES;
    [super viewDidLoad];
}
-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
}
-(void)viewDidDisappear:(BOOL)animated{
    [super viewDidDisappear:animated];
}
-(void)viewDidLayoutSubviews{
}
-(void)viewWillLayoutSubviews{
    [super viewWillLayoutSubviews];
    SKView *skView = (SKView*)self.originalContentView;
    if (!skView.scene) {
        SKScene *scene = [GameScene sceneWithSize:skView.bounds.size];

        [skView presentScene:scene];
        //skView.showsPhysics = YES;


    }

}

    return NO;
}

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

    } else {
