iPhone X Ad Rendering

This guide demonstrates best practices on how to code your apps to render ads correctly on the iPhone X.

Prerequisites

Banner ads must be placed in the "Safe Area" to avoid being obscured by rounded corners, sensor housing, and the Home indicator. On this page you'll find examples of how to add constraints to position a banner to the top or bottom of the Safe Area. Both storyboard and programmatic constraints are demonstrated in an environment that supports iOS 9+ and Xcode 9+. Workarounds for earlier versions of iOS and Xcode are also noted.

Storyboard/Interface Builder

If your app uses Interface Builder, first, ensure you have enabled Safe Area layout guides. To do this you need to be running Xcode 9+ and targeting iOS 9+.

Open your Interface Builder file and click on your view controller scene. You will see the Interface Builder Document options on the right. Check Use Safe Area Layout Guides and ensure you're building for iOS 9.0 and later as a minimum.

We recommend you constrain the banner to the size required using width and height constraints.

Now you can align the banner to the top of the Safe Area by constraining the GADBannerView's Top property to the top of the Safe Area:

Similarly, you can align the banner to the bottom of the Safe Area by constraining the GADBannerView's Bottom property to the bottom of the safe area:

Your constraints should now look similar to the screenshot below (sizing/positioning can vary):

ViewController

Here's a simple view controller code snippet that does the minimum needed to show a banner in a GADBannerView as configured in the storyboard above:

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];
}

Aligning banners to the edge of safe area

If you wish to have a left- or right-aligned banner, constrain the left/right edge of the banner to the left/right edge of the safe area and not the left/right edge of the superview.

If you have Use Safe Area Layout Guides enabled, interface builder will default to using the safe area edges when adding constraints to the view.

Supporting iOS 8 and below

If you want to support iOS 8 or below using Interface Builder, you should uncheck Use Safe Area Layout Guides for your Interface Builder files and storyboards.

Now you can add constraints to the bottom of the top layout guide (instead of top of Safe Area):

Also add constraints to the top of the bottom layout guide (instead of bottom of Safe Area):

For full-width banners (only affected by Safe Area in landscape), these layout guides don't exist. The safe option in Interface Builder is making your left and right edge constraints relative to the margins:

This will offset the edge of the banner a little from the edge of the superview/Safe Area, assuring that your banner won't be obscured in landscape orientation on iPhone X. You can also achieve the desired result programmatically.

Programmatic

If your app creates banner ads programmatically, you can define constraints and position the banner ad in code. This example (for iOS version 7.0 and higher) shows how to constrain a banner to be centered horizontally at the bottom of the Safe Area:

Swift

class ViewController: UIViewController {

  var bannerView: GADBannerView!

  override func viewDidLoad() {
    super.viewDidLoad()

    // Instantiate the banner view with your desired banner size.
    bannerView = GADBannerView(adSize: kGADAdSizeBanner)
    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))
  }

}

  // Replace this ad unit ID with your own ad unit ID.

                                                         constant:0]];
}

@end

The techniques above can easily be used for constraining to the top of the safe area by modifying the attributes and anchors used.

Smart banners

If you're using smart banners, particularly in landscape, we recommend that you use constraints to align the banner edges to the left and right edges of the safe area.

In interface builder, this is supported back to iOS 9 by checking the Use Safe Area Layout Guides option as outlined above.

In code, you should make your edge constraints relative to the safe area layout guides where available. Here is a code snippet which adds a banner view to the view and constrains to the bottom of the view, full-width:

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,
                                        relatedBy: .equal,
                                        toItem: view,
                                        attribute: .leading,
                                        multiplier: 1,
                                        constant: 0))
  view.addConstraint(NSLayoutConstraint(item: bannerView,
                                        attribute: .trailing,
                                        relatedBy: .equal,
                                        toItem: view,
                                        attribute: .trailing,
                                        multiplier: 1,
                                        constant: 0))
  view.addConstraint(NSLayoutConstraint(item: bannerView,
                                        attribute: .bottom,
                                        relatedBy: .equal,
                                        toItem: bottomLayoutGuide,
                                        attribute: .top,
                                        multiplier: 1,
                                        constant: 0))
}

                                                         constant:0]];
}

Native ads

If your app pins native ads to the top or bottom of the screen, the same principles apply for native ads as they do for banner ads. The key difference is instead of adding constraints to a GADBannerView, you'll need to add constraints to your GADNativeAppInstallAdView and GADNativeContentAdView (or the containing view for the ad) in order to respect the Safe Area layout guides. For native views we recommend providing more explicit size constraints.

Interstitial and rewarded ads

Full screen ad formats, including interstitial and rewarded ads, are rendered by the Google Mobile Ads SDK. There will be an update to the Google Mobile Ads SDK to ensure that ad elements like the close button render in the right spot. We will update the release notes and this documentation page when this change is available.
