設置Admob橫幅出現在屏幕底部

Question

我目前使用此代碼來顯示Admob請求;

如果我使用這段代碼，橫幅出現，但在屏幕的頂部不是底部;

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]]; 

我該如何改變它以顯示在屏幕的底部？

方法1：將此代碼放在代碼的底部。

//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);

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;

您就可以在谷歌廣告開發者博客提出的解決方案： http://googleadsdeveloper.blogspot.com/2012/06/keeping-smart-banner-docked-to-bottom.html

// Initialize the banner docked to the bottom of the screen. 
// We start in a portrait orientation so use kGADAdSizeSmartBannerPortrait. 
    CGPoint origin = CGPointMake(0.0, 
           self.view.frame.size.height - 
           CGSizeFromGADAdSize(
            kGADAdSizeSmartBannerPortrait).height); 

    self.adBanner = [[[GADBannerView alloc] 
        initWithAdSize:kGADAdSizeSmartBannerPortrait 
          origin:origin] autorelease]; 

//Continue rest of initialization here 

確保使用self.view.frame.size.width在Y座標如果您使用的是kGADAdSizeSmartBannerLandscape。
