ios - iAd 卡住游戏场景

Question

我正在使用 SpriteKit 开发游戏。我在场景的 View 中显示了 iAds。当触摸广告 View 中的广告时，广告会出现，但是，如果我交叉(X)/关闭广告，游戏中的场景就会被卡住。当广告出现和消失时，我不会暂停场景或对事件做任何事情。如果我再次触摸广告(现在这是第二次卡住场景)并返回场景，场景就会解冻并且一切都开始按预期进行(奇怪的)。我不确定 iAd 或我的应用程序中的问题在哪里？

// Method is called when the iAd is loaded.
-(void)bannerViewDidLoadAd:(ADBannerView *)banner {
    NSLog(@"Banner did load");
    [self animateAdBanner];
}

-(void) animateAdBanner{

if(iAdsEnable){

    [UIView animateWithDuration:6 delay:8
        options:UIViewAnimationOptionAllowUserInteraction
        animations:^{
            [self.adBanner setAlpha:0.85];
        }
        completion:^(BOOL finished){
            if(finished){
             //[self.adBanner setAlpha:0.7];
            }

        }];



}
}

根据 Apple 的 ADBannerViewDelegate 协议(protocol)引用:

bannerViewActionShouldBegin:willLeaveApplication:

If the willLeave parameter is YES, then your application is moved to the background shortly after this method returns. In this situation, your method implementation does not need to perform additional work. If willLeave is set to NO, then the triggered action will cover your application’s user interface to show the advertising action. Although your application continues to run normally, your implementation of this method should disable activities that require user interaction while the action is executing. For example, a game might pause its game play until the user finishes watching the advertisement.

基本上意味着当您的游戏被插入后台时，游戏将暂停。

当横幅 View 完成它的 Action 时，委托(delegate)有一个更进一步的方法来通知你:

bannerViewActionDidFinish:

Discussion If your delegate paused activities before allowing an action to run, it should resume those activities when this method is called.

看来您可以使用上述委托(delegate)方法来实现您自己的暂停/取消暂停，或者您可以在您的场景中使用 NSNotification 在您的应用程序分别进入后台和前台时暂停/取消暂停。

[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(pause)
name:UIApplicationWillResignActiveNotification
object:nil];

[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(unPause)
name:UIApplicationWillEnterForegroundNotification
object:nil];
