问题描述

我目前正在使用此代码来显示 Admob 请求；

I am currently using this code to display an Admob request;

如果我使用此代码，横幅会出现，但在屏幕顶部而不是底部；

If I use this code, the banner appears, but at the top of the screen not the bottom;

CGRect screenRect = [[UIScreen mainScreen] bounds];
    CGFloat screenWidth = screenRect.size.width;
    CGFloat screenHeight = screenRect.size.height;
    CGFloat screenXPos = (screenWidth/2);
    CGFloat screenYPos = screenHeight - kGADAdSizeBanner.size.height;
    [bannerView_ setCenter:CGPointMake(screenXPos, screenYPos)];
    bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerLandscape];
    bannerView_.adUnitID = ADMOB_ID;
    bannerView_.rootViewController = self;
    bannerView_.adUnitID = ADMOB_ID;
    bannerView_.rootViewController = self;
    [self.view addSubview:bannerView_];
    [bannerView_ loadRequest:[GADRequest request]];

如何将其更改为显示在屏幕底部?

How would I change this to show at the bottom of the screen instead?

推荐答案

方法一:把这段代码放在代码的底部.

METHOD 1: Put this code in bottom of your code.

//TRY_1:
        bannerView_.frame = CGRectMake(screenWidth/2.0 - bannerView_.frame.size.width/2.0, screenHeight - bannerView_.frame.size.height,
                                       bannerView_.frame.size.width,bannerView_.frame.size.height);
//OR TRY_2:
        bannerView_.frame = CGRectMake(screenHeight/2.0 - bannerView_.frame.size.width/2.0, screenWidth - bannerView_.frame.size.height,
                                       bannerView_.frame.size.width,bannerView_.frame.size.height);

方法2:详细清洁方式

typedef enum _bannerType
{
    kBanner_Portrait_Top,
    kBanner_Portrait_Bottom,
    kBanner_Landscape_Top,
    kBanner_Landscape_Bottom,
}CocosBannerType;

//In .h declare  CocosBannerType mBannerType;

-(void)createAdmobAds
 {
    mBannerType = kBanner_Portrait_Bottom; //kBanner_Portrait_Top

    AppController *app =  (AppController*)[[UIApplication sharedApplication] delegate];
    // Create a view of the standard size at the bottom of the screen.
    // Available AdSize constants are explained in GADAdSize.h.

    if(mBannerType <= kBanner_Portrait_Bottom)
        mBannerView = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
    else
        mBannerView = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerLandscape];

    // Specify the ad's "unit identifier." This is your AdMob Publisher ID.
    mBannerView.adUnitID = MY_BANNER_UNIT_ID;

    // Let the runtime know which UIViewController to restore after taking
    // the user wherever the ad goes and add it to the view hierarchy.

    mBannerView.rootViewController = app.navController;
    [app.navController.view addSubview:mBannerView];

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

    CGRect screenRect = [[UIScreen mainScreen] bounds];
    CGSize s = screenRect.size;

    CGRect frame = mBannerView.frame;

    off_x = 0.0f;

        }

        {
            off_y = -frame.size.height;

        }
            break;
