ios - DFP 问题 : No ad to show

Question

我的应用程序在 UIScrollView 中提供了三个广告(通过 DoubleClick for Publisher)。我使用适用于 iOS 的旧版 AdMob SDK，一切正常。我决定下载新版本，因为 AppStore 出现了一些问题。添加新版本后，出现错误:

Error Domain=com.google.ads Code=1 "Request Error: No ad to show." UserInfo=0x14e88e60 {NSLocalizedDescription=Request Error: No ad to show., NSLocalizedFailureReason=Request Error: No ad to show.}

广告具有自定义尺寸的创意 (320x125)。添加它的 UIScrollView 是 960x125，它被放置为 UITableView 的标题。

横幅代码:

- (void)viewDidLoad {
    [super viewDidLoad];

    DFPBannerView *bannerView = (DFPBannerView *)self.view;
    [self preventBannerCaptureTouch:bannerView];
    // Create a view of the standard size at the bottom of the screen.
    // Available AdSize constants are explained in GADAdSize.h.
    //bannerView = [[DFPBannerView alloc] initWithAdSize:CG];
    bannerView.adSize = GADAdSizeFromCGSize(CGSizeMake(320, 125));
    // Specify the ad's "unit identifier." This is your DFP ad unit ID.
    bannerView.adUnitID = self.adUnitID;

    [bannerView setAppEventDelegate:self];
    [bannerView setDelegate:self];

    bannerView.rootViewController = self.bannerOwner;

    // Initiate a generic request to load it with an ad.
    GADRequest *request = [[GADRequest alloc] init];
    //request.testDevices = [NSArray arrayWithObjects: nil];

    [bannerView loadRequest:request];

    spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
    spinner.center = CGPointMake(self.view.frame.size.width / 2, self.view.frame.size.height / 2);
    [self.view addSubview:spinner];
    [spinner startAnimating];
}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
}

- (void)preventBannerCaptureTouch:(GADBannerView*)bannerView {
    for (UIWebView *webView in bannerView.subviews) {
        if ([webView isKindOfClass:[UIWebView class]]) {
            webView.scrollView.bounces = NO;

            for (UIGestureRecognizer *gestureRecognizer in webView.gestureRecognizers) {
                if ([gestureRecognizer isKindOfClass:NSClassFromString(@"GADImpressionTicketGestureRecognizer")]) {
                    gestureRecognizer.delegate = self;
                }
            }

            for (id view in [[[webView subviews] objectAtIndex:0] subviews]) {
                if ([view isKindOfClass:NSClassFromString(@"UIWebBrowserView")]) {
                    for (UIGestureRecognizer *recognizer in [view gestureRecognizers]) {
                        if ([recognizer isKindOfClass:NSClassFromString(@"UIWebTouchEventsGestureRecognizer")]) {
                            [view removeGestureRecognizer:recognizer];
                        }
                    }
                    return;
                }
            }
        }

        [webView setTintColor:[UIColor whiteColor]];
    }
}

- (void)viewWillUnload {
    [super viewWillUnload];

    DFPBannerView *bannerView = (DFPBannerView *)self.view;
    bannerView.appEventDelegate = nil;
    bannerView.delegate = nil;
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.bannerSlider bannerTouchesBegan:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.bannerSlider bannerTouchesEnded:touches withEvent:event];
}

- (void)adViewDidReceiveAd:(GADBannerView *)bannerView {
    [spinner stopAnimating];
}

- (void)adView:(GADBannerView *)bannerView didFailToReceiveAdWithError:(GADRequestError *)error {
    NSLog(@"GOOGLE Ad ERROR: %@", error);
    [spinner stopAnimating];
}

UIScrollView代码:

- (void)viewDidLoad {
    [super viewDidLoad];

    UIScrollView *view = (UIScrollView *)self.view;
    view.bounces = NO;
    // @"/6499/example/banner"
    GWBannerController *oneController = [[GWBannerController alloc] initWithNibName:@"BannerView" bundle:nil bannerOwner:self.bannerOwner bannerSlider:self ID:@"/XXX/iOSLeaderBanner_One"];
    //GWBannerController *oneController = [[GWBannerController alloc] initWithNibName:@"BannerView" bundle:nil bannerOwner:self.bannerOwner bannerSlider:self ID:@"/6499/example/banner"];
    oneController.view.frame = CGRectMake(0, 0, 320, 125);
    [view addSubview:oneController.view];

    [bannerArray addObject:oneController];

    GWBannerController *twoController = [[GWBannerController alloc] initWithNibName:@"BannerView" bundle:nil bannerOwner:self.bannerOwner bannerSlider:self ID:@"/XXX/iOSLeaderBanner_Two"];
    twoController.view.frame = CGRectMake(320, 0, 320, 125);
    [view addSubview:twoController.view];

    [bannerArray addObject:twoController];

    GWBannerController *threeController = [[GWBannerController alloc] initWithNibName:@"BannerView" bundle:nil bannerOwner:self.bannerOwner bannerSlider:self ID:@"/XXX/iOSLeaderBanner_Three"];
    threeController.view.frame = CGRectMake(640, 0, 320, 125);
    [view addSubview:threeController.view];

    [bannerArray addObject:threeController];

    [view setContentSize:CGSizeMake(960, 125)];
    [self startTimer];
}

广告服务器将返回此消息主要是因为您的广告单元 ID 没有广告。检查您的广告单元 ID 是否正确。如果您的横幅宽度/高度为 0，您将收到相同的错误。确保您的 adUnitID 是完美的。
