iPhone X 广告呈现

本指南介绍了一些最佳做法,有助于您了解如何通过编写应用代码来呈现广告。 可在 iPhone X 上正确设置。

前提条件

横幅广告必须放置在 “安全 区域” 以免被圆角、传感器外壳和主屏幕遮挡 指示器。本页将举例说明如何为广告添加限制条件 将横幅广告放置在安全区域的顶部或底部。

Storyboard/Interface Builder

如果您的应用使用 Interface Builder,请先确保您已启用“安全区域” 布局指南。为此,您需要运行 Xcode 9 及更高版本并以 iOS 9 及更高版本为目标。

打开 Interface Builder 文件,然后点击您的视图控制器场景。您 将看到右侧的 Interface Builder 文档选项。选中使用 安全区域布局指南,并确保构建适用于 iOS 9.0 及更高版本 最低

我们建议您使用宽度和 高度限制。

现在,您可以将横幅广告与安全区域的顶部对齐,只需限制 GADBannerView 的 Top 属性移至安全区域的顶部:

同样,您也可通过将横幅广告与安全区域的底部对齐: 将 GADBannerView 的 Bottom 属性限制在安全 领域:

现在,您的约束条件应类似于下面的屏幕截图。 (大小/位置可能会有所不同):

ViewController

这是一个简单的视图控制器代码段,执行 在 GADBannerView 中显示横幅广告(如上述 Storyboard 中所配置):

Swift

class ViewController: UIViewController {

  /// The banner view.
  @IBOutlet var bannerView: GADBannerView!

  override func viewDidLoad() {
    super.viewDidLoad()
    // Replace this ad unit ID with your own ad unit ID.
    bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"
    bannerView.rootViewController = self
    bannerView.load(GADRequest())
  }

}

Objective-C

@interface ViewController()

@property(nonatomic, strong) IBOutlet GADBannerView *bannerView;

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  // Replace this ad unit ID with your own ad unit ID.
  self.bannerView.adUnitID = @"ca-app-pub-3940256099942544/2934735716";
  self.bannerView.rootViewController = self;
  GADRequest *request = [GADRequest request];
  [self.bannerView loadRequest:request];
}

将横幅广告与安全区域边缘对齐

如果您希望横幅左对齐或右对齐,请限制 横幅的左侧/右侧边缘与安全区域左侧/右侧边缘之间的距离 而不是父视图的左侧/右侧边缘。

如果您已启用使用安全区域布局指南,则界面构建器会 为视图添加约束条件时,默认使用安全区域边缘。

程序化

如果您的应用以程序化方式制作横幅广告,您可以定义限制条件并 在代码中放置横幅广告的位置。此示例展示了如何将横幅广告 在安全区域底部水平居中:

Swift

class ViewController: UIViewController {

  var bannerView: GADBannerView!

  override func viewDidLoad() {
    super.viewDidLoad()

    // Instantiate the banner view with your desired banner size.
    bannerView = GADBannerView(adSize: GADAdSizeBanner)
    addBannerViewToView(bannerView)
    bannerView.rootViewController = self
    // Set the ad unit ID to your own ad unit ID here.
    bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"
    bannerView.load(GADRequest())
  }

  func addBannerViewToView(_ bannerView: UIView) {
    bannerView.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(bannerView)
    if #available(iOS 11.0, *) {
      positionBannerAtBottomOfSafeArea(bannerView)
    }
    else {
      positionBannerAtBottomOfView(bannerView)
    }
  }

  @available (iOS 11, *)
  func positionBannerAtBottomOfSafeArea(_ bannerView: UIView) {
    // Position the banner. Stick it to the bottom of the Safe Area.
    // Centered horizontally.
    let guide: UILayoutGuide = view.safeAreaLayoutGuide

    NSLayoutConstraint.activate(
      [bannerView.centerXAnchor.constraint(equalTo: guide.centerXAnchor),
       bannerView.bottomAnchor.constraint(equalTo: guide.bottomAnchor)]
    )
  }

  func positionBannerAtBottomOfView(_ bannerView: UIView) {
    // Center the banner horizontally.
    view.addConstraint(NSLayoutConstraint(item: bannerView,
                                          attribute: .centerX,
                                          relatedBy: .equal,
                                          toItem: view,
                                          attribute: .centerX,
                                          multiplier: 1,
                                          constant: 0))
    // Lock the banner to the top of the bottom layout guide.
    view.addConstraint(NSLayoutConstraint(item: bannerView,
                                          attribute: .bottom,
                                          relatedBy: .equal,
                                          toItem: self.bottomLayoutGuide,
                                          attribute: .top,
                                          multiplier: 1,
                                          constant: 0))
  }

}

智能横幅广告

如果您使用的是智能横幅广告,尤其是横向横幅广告,建议您 使用约束条件将横幅广告的边缘与 安全区域

在 Interface Builder 中,通过检查 使用安全区域布局指南选项 如上所述

在代码中,您应设置相对于安全区域的边缘约束条件 布局指南(如果有)。下面这段代码可将横幅广告视图 附加到视图并约束到视图底部,即全宽:

Swift

func addBannerViewToView(_ bannerView: GADBannerView) {
  bannerView.translatesAutoresizingMaskIntoConstraints = false
  view.addSubview(bannerView)
  if #available(iOS 11.0, *) {
    // In iOS 11, we need to constrain the view to the safe area.
    positionBannerViewFullWidthAtBottomOfSafeArea(bannerView)
  }
  else {
    // In lower iOS versions, safe area is not available so we use
    // bottom layout guide and view edges.
    positionBannerViewFullWidthAtBottomOfView(bannerView)
  }
}

// MARK: - view positioning
@available (iOS 11, *)
func positionBannerViewFullWidthAtBottomOfSafeArea(_ bannerView: UIView) {
  // Position the banner. Stick it to the bottom of the Safe Area.
  // Make it constrained to the edges of the safe area.
  let guide = view.safeAreaLayoutGuide
  NSLayoutConstraint.activate([
    guide.leftAnchor.constraint(equalTo: bannerView.leftAnchor),
    guide.rightAnchor.constraint(equalTo: bannerView.rightAnchor),
    guide.bottomAnchor.constraint(equalTo: bannerView.bottomAnchor)
  ])
}

func positionBannerViewFullWidthAtBottomOfView(_ bannerView: UIView) {
  view.addConstraint(NSLayoutConstraint(item: bannerView,
                                        attribute: .leading,

                                        constant: 0))

原生广告

如果您的应用将原生广告固定在屏幕的顶部或底部, 适用于原生广告的原则和适用于横幅广告的原则同样适用。 主要区别在于,您不必为 GADBannerView 添加约束条件,而是 需要向 GADUnifiedNativeAdView(或包含视图)添加约束条件 ),以遵守安全区域布局指南。对于原生视图 建议您提供更明确的尺寸限制值。

插页式广告和激励广告

从 7.26.0 版开始,Google 移动广告 SDK 完全支持插页式广告和 激励广告格式。
