ios - 如何将 AdMob 横幅放置在底部？

Question

如何将 AdMob 横幅放置在屏幕底部？当 iAd 横幅无法加载但 AdMob 横幅出现在屏幕顶部时，我使用 AdMob 作为中继。我查了很多方法，但没有一个有效。

这是我的代码:.h

@interface Class_ScoreViewController : UIViewController <UITextFieldDelegate,ADBannerViewDelegate>
{
    GADBannerView *bannerViewAdMob_;
    ADBannerView *adView;
}
@property (nonatomic,retain) IBOutlet ADBannerView *adView;

.m

@synthesize adView;
- (void)bannerViewDidLoadAd:(ADBannerView *)banner{
    NSLog(@"-----------Displaying Ad-------------");
    [adView setHidden:NO];
    bannerViewAdMob_.hidden = YES;
}

-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{
    NSLog(@"------------Ad Error-------------");
    [adView setHidden:YES];
    CGSize screenSize = [[UIScreen mainScreen] bounds].size;


    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        if (screenSize.height > 480.0f) {
            //iPhone 5
            bannerViewAdMob_ = [[GADBannerView alloc] initWithFrame:CGRectMake(0.0, self.view.frame.size.height- 89 -GAD_SIZE_320x50.height, GAD_SIZE_320x50.width, GAD_SIZE_320x50.height)];

        }
        else{
            //iPhone 4
            bannerViewAdMob_ = [[GADBannerView alloc] initWithFrame:CGRectMake(0.0, self.view.frame.size.height-GAD_SIZE_320x50.height, GAD_SIZE_320x50.width, GAD_SIZE_320x50.height)];


        }
    // Create a view of the standard size at the top of the screen.
    // Available AdSize constants are explained in GADAdSize.h.
    bannerViewAdMob_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];

    // Specify the ad's "unit identifier". This is your AdMob Publisher ID.
    bannerViewAdMob_.adUnitID = @"xxxxxxxxxxxxxxx";

    // Let the runtime know which UIViewController to restore after taking
    // the user wherever the ad goes and add it to the view hierarchy.
    bannerViewAdMob_.rootViewController = self;
    [self.view addSubview:bannerViewAdMob_];

    // Initiate a generic request to load it with an ad.
    [bannerViewAdMob_ loadRequest:[GADRequest request]];
    }
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    adView.delegate = self;
    [adView setHidden:YES];
}

你正在覆盖你的变量，检查

 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        if (screenSize.height > 480.0f)
            bannerViewAdMob_ = [[GADBannerView alloc] initWithFrame:CGRectMake(0.0, self.view.frame.size.height- 89 -GAD_SIZE_320x50.height, GAD_SIZE_320x50.width, GAD_SIZE_320x50.height)];
        else
            bannerViewAdMob_ = [[GADBannerView alloc] initWithFrame:CGRectMake(0.0, self.view.frame.size.height-GAD_SIZE_320x50.height, GAD_SIZE_320x50.width, GAD_SIZE_320x50.height)];

    bannerViewAdMob_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner]; // here is you overwrite

正确放置它 - 在调用 initWithAdSize 后设置框架/边界属性
