问题描述
处理我的第一个游戏并尝试在其中实施广告。
Working on my first game and trying to implement ads in to it.
我在viewController.h中声明了以下内容
I've declared the following in my viewController.h
#import <UIKit/UIKit.h>
#import <SpriteKit/SpriteKit.h>
#import <iAd/iAd.h>
@interface ViewController : UIViewController <ADBannerViewDelegate>
在我的实施文件中，我得到了以下（因为我需要横向布局而使用）
And in my implementation file I've Got the following (used because I need landscape layout)
- (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，当我立即运行应用程序时崩溃（在下面记录） - 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 - 任何人有任何想法？
However when I run the app instantly crashes (log below) - if I change self.canDisplayBannerAdds = NO; the app runs fine - I have a feeling this is ridiculously simple but I can't see it for looking - anyone got any ideas?

推荐答案
当 canDisplayBannerAdds 设置为YES时，您需要在控制器上使用 originalContentView 保持您的观点。
When canDisplayBannerAdds is set to YES, you need to use originalContentView on your controller to get hold of your view.
尝试使用以下代码来获取您的观点：
Try using the following code to get hold of your view:
SKView * skView = self.originalContentView;
