Ios iPad上的AppLovin横幅广告崩溃

我正在尝试将AppLovin横幅广告集成到我的通用应用程序中。在iPhone上，它工作正常。但在iPad上，当带有横幅的视图被用户留下/删除后，应用程序崩溃

下面是显示横幅广告的代码：

// Create new AdView
adView = [[ALAdView alloc] initBannerAd];

//
// (Optional) Position the ad at the bottom of screen. By default
// it would be postitioned at (0,0)
//
adView.frame = CGRectMake( 0,
                          self.view.frame.size.height - adView.frame.size.height,
                          adView.frame.size.width,
                          adView.frame.size.height );

adView.autoresizingMask =
UIViewAutoresizingFlexibleLeftMargin |
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleRightMargin;

// (Mandatory) Add the ad into current view
[self.view addSubview:adView];

// (Mandatory) Trigger loading of the new ad.
[adView loadNextAd];

如果注释掉addSubview调用，则不会发生崩溃。似乎添加的子视图没有得到统一化或其他东西

非常感谢你的帮助

问题在于未指定父控制器。添加

adView.parentController = self;

解决了这个问题。以下是最终代码：

// Create new AdView
adView = [[ALAdView alloc] initBannerAd];
adView.parentController = self;

// (Optional) Position the ad at the bottom of screen.
// By default it would be postitioned at (0,0)
adView.frame = CGRectMake( 0,
                          self.view.frame.size.height - adView.frame.size.height,
                          adView.frame.size.width,
                          adView.frame.size.height );

adView.autoresizingMask =
UIViewAutoresizingFlexibleLeftMargin |
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleRightMargin;

// (Mandatory) Add the ad into current view
[self.view addSubview:adView];

// (Mandatory) Trigger loading of the new ad.
[adView loadNextAd];

对于未来的用户。。。要在上面移动它。。。adView.frame=CGRectMake（0,0，adView.frame.size.width，adView.frame.size.height）；“initBannerAd”现在标记为已弃用。。。什么是更新代码？
