如何在底部放置AdMob横幅？

Question

如何将横幅广告形式AdMob放在屏幕底部？ 当iAd标语无法加载时，我将AdMob用作中继，但AdMob标语显示在屏幕顶部。 我已经找到了许多方法来做到这一点，但是没有一种可以工作。

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];
}

您要覆盖变量，请检查

 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-在调用initWithAdSize之后设置框架/边界属性
