共享的iAd横幅bannerViewDidLoadAd未被调用

我正在使用以下代码来设置共享的iAd横幅广告。

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { _adView = [[ADBannerView alloc]init]; } 

ViewController.m

 -(void) viewWillAppear:(BOOL)animated { AppDelegate *appdelegate = (AppDelegate *)[[UIApplication sharedApplication ]delegate]; _adView = [appdelegate adView]; _adView.delegate = self; self.canDisplayBannerAds = true; } - (void)bannerViewDidLoadAd:(ADBannerView *)banner { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1]; [banner setAlpha:1]; [UIView commitAnimations]; } - (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1]; [banner setAlpha:0]; [UIView commitAnimations]; } 

bannerView:didFailToReceiveAdWithError正在按预期调用，但是bannerViewDidLoadAd永远不会被调用。 我试图在iAd标题加载时在屏幕上移动一些button。

您的共享横幅似乎不只是一个ADBannerView 。 看起来你已经在你的AppDelegate.h和你的ViewController.h为你的ADBannerView设置了多个ADBannerView 。 此外， self.canDisplayBannerAds = true正在为您创build一个全新的，不同的 ADBannerView 。 self.canDisplayBannerAds = true可以用于在您的应用程序中实现self.canDisplayBannerAds = true方式。 这将为您创build一个ADBannerView ，并根据是否从iAdnetworking收到广告来显示或隐藏ADBannerView 。 如果您打算自己实现ADBannerView则需要从viewDidLoad删除此项。

以下是您的共享ADBannerView应该如下所示：

AppDelegate.h

 #import <UIKit/UIKit.h> @import iAd; @interface AppDelegate : UIResponder <UIApplicationDelegate> { } @property (strong, nonatomic) UIWindow *window; @property (strong, nonatomic) ADBannerView *iAdView; @end 

AppDelegate.m

 -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { _iAdView = [[ADBannerView alloc]init]; return YES; } 

ViewController.h

 #import <UIKit/UIKit.h> #import "AppDelegate.h" @interface ViewController : UIViewController <ADBannerViewDelegate> @end 

ViewController.m

 #import "ViewController.h" @interface ViewController () @end @implementation ViewController { AppDelegate *appDelegate; } -(void)viewDidLoad { [super viewDidLoad]; appDelegate = (AppDelegate *)[[UIApplication sharedApplication ]delegate]; appDelegate.iAdView.delegate = self; appDelegate.iAdView.frame = CGRectMake(0, 0, appDelegate.iAdView.frame.size.width, appDelegate.iAdView.frame.size.height); [self.view addSubview:appDelegate.iAdView]; // You created another adView property in your ViewController.h? //_adView = [appdelegate adView]; //_adView.delegate = self; // This will actually create ANOTHER ADBannerView // Do not use when creating your own ADBannerView //self.canDisplayBannerAds = true; } -(void)bannerViewDidLoadAd:(ADBannerView *)banner { NSLog(@"iAd LOADED"); [UIView beginAnimations:nil context:NULL]; appDelegate.iAdView.alpha = 1.0; [UIView commitAnimations]; } -(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error { NSLog(@"iAd FAILED"); [UIView beginAnimations:nil context:NULL]; appDelegate.iAdView.alpha = 0.0; [UIView commitAnimations]; }
