iAd錯誤如何解決？

Question

我將iAd添加到TableView底部的UIVIew中，當快速向上/向下滾動時也會出錯。

碼

- (void)viewDidLoad {
    //NSLog(@"viewDidLoad");
    if(NSClassFromString(@"ADBannerView") != nil) {
        ADBannerView *adView = [[ADBannerView alloc] initWithFrame:CGRectMake(0,0,0,0)];
        adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifier320x50;
        adView.delegate = self;
        adView.hidden = YES;
        [self.iAdBanner addSubview:adView];
        [UIView beginAnimations:@"animateAdBannerOff" context:NULL];
        // assumes the banner view is at the top of the screen.
        adView.frame = CGRectOffset(adView.frame, 0, -150);
        [UIView commitAnimations];
        //[adView release];
    }
    else {
        //NSLog(@"iad not available");
    }

    [super viewDidLoad];
}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner {
    //NSLog(@"bannerViewDidLoadAd");
    //[self moveBannerViewOnscreen];
    if (banner.hidden)
    {
        [UIView beginAnimations:@"animateAdBannerOn" context:NULL];
        // assumes the banner view is offset 50 pixels so that it is not visible.
        banner.frame = CGRectOffset(banner.frame, 0, 150);
        banner.hidden = NO;
        [UIView commitAnimations];
        //self.bannerIsVisible = YES;
    }
}

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
    //NSLog(@"bannerView error");
    //[self moveBannerViewOffscreen];
    //* 
    if (!banner.hidden)
    {
        [UIView beginAnimations:@"animateAdBannerOff" context:NULL];
        // assumes the banner view is at the top of the screen.
        banner.frame = CGRectOffset(banner.frame, 0, -150);
        [UIView commitAnimations];//*/
        banner.hidden = YES;
    }
}

- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave {
    //NSLog(@"bannerViewActionShouldBegin");
    //[super bannerViewActionShouldBegin:banner willLeaveApplication:willLeave];
    return YES;
}

- (void)bannerViewActionDidFinish:(ADBannerView *)banner {
    //NSLog(@"bannerViewActionDidFinish");
}

Answer 1

頭文件可能更容易回答，但是您是否設置了接口以實現委托接口？ 您需要在UIViewController中執行此操作，以捕獲iAd消息。 並且不要忘記#import。

如果您使用Interface Builder進行設置-而您並沒有使用AFAICT進行操作，而只是即時創建iAd-則將iAd委托設置為視圖時會遇到其他問題，方法是將iAd委托連接到“文件的所有者”套接字。

無論如何，請檢查您的頭文件，希望對您有幫助。
