ios - GADBannerView 没有设置高度

Question

有人知道如何以编程方式显示 50pt 高度的 GADBannerView 吗？

在我看来DidLoad，

int heightOfBanner = 50;
GADBannerView *banner = 
 [[GADBannerView alloc]
 initWithAdSize:GADAdSizeFullWidthPortraitWithHeight(heightOfBanner)
 origin:CGPointMake(0, CGSizeFromGADAdSize(kGADAdSizeBanner).height)];
banner.adUnitID = @"ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxxxxxx";
banner.rootViewController = self;
[self.view addSubview:banner];

[banner loadRequest:[GADRequest request]];

以上代码没有显示任何内容。

但是当 heightOfBanner 设置为更高的值(例如 200)时，效果很好(但横幅的高度不是 50)。

我的播客文件如下:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
pod 'Google-Mobile-Ads-SDK', '~> 7.0'

我成功地完成了“pod install”。

不要使用精确的尺寸来绘制您的 GADBannerView。您应该相对于屏幕尺寸设置其框架和原点。这将在屏幕底部显示您的 GADBannerView

    // Get device screen size
    // For example, screenBounds on an iPhone 6 will look like this
    // screenBounds.origin.x == 0
    // screenBounds.origin.y == 0
    // screenBounds.size.width == 375
    // screenBounds.size.height == 667
    CGRect screenBounds = [[UIScreen mainScreen] bounds];

    // Setup AdMob view
    // Create the GADBannerView
    adMobView = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];

    // Use your BANNER_UNIT_ID
    adMobView.adUnitID = BANNER_UNIT_ID;
    adMobView.rootViewController = self;
    [adMobView loadRequest:[GADRequest request]];

    // This sets the frame origin at (0,0) which would be the top left of the device screen
    // screenBounds.size.width and adMobView.bounds.size.height sets the size of the GADBannerView
    [adMobView setFrame:CGRectMake(0, 0, screenBounds.size.width, adMobView.bounds.size.height)];

    // This will take the center of our GADBannerView and move it to a point (x,y)
    // We want our GADBannerView.center in the center of the device screen
    // So lets get the width of our screen and divide it by 2. We do this with screenBounds.size.width / 2
    // We also want our GADBannerView to be at the bottom of the screen
    // So lets get the height of our screen with screenBounds.size.height
    // Remember were talking about the center of our GADBannerView here so if we just set it to that
    // Half of our GADBannerView's height will be cut off by the bottom of the screen
    // So lets subtract half of our GADBannerView's height to fix that with adMobView.bounds.size.height / 2
    adMobView.center = CGPointMake(screenBounds.size.width / 2, screenBounds.size.height - (adMobView.bounds.size.height / 2));

    // Add it to our view
    [self.view addSubview:adMobView];
