Annunci banner

class ViewController: UIViewController {

  var bannerView: GAMBannerView!

  override func viewDidLoad() {
    super.viewDidLoad()

    let viewWidth = view.frame.inset(by: view.safeAreaInsets).width

    // Here the current interface orientation is used. Use
    // GADLandscapeAnchoredAdaptiveBannerAdSizeWithWidth or
    // GADPortraitAnchoredAdaptiveBannerAdSizeWithWidth if you prefer to load an ad of a
    // particular orientation,

    bannerView = GAMBannerView(adSize: adaptiveSize)

    addBannerViewToView(bannerView)

    view.addSubview(bannerView)
    // This example doesn't give width or height constraints, as the provided
    // ad size gives the banner an intrinsic content size to size the view.
    view.addConstraints(
      [NSLayoutConstraint(item: bannerView,
                          attribute: .bottom,
                          relatedBy: .equal,
                          toItem: view.safeAreaLayoutGuide,

                          attribute: .centerX,
                          relatedBy: .equal,
                          toItem: view,

                          multiplier: 1,
                          constant: 0)
      ])
  }
}

SwiftUI

Per utilizzare un GAMBannerView, crea un UIViewRepresentable:

private struct BannerView: UIViewRepresentable {
  let adSize: GADAdSize

  init(_ adSize: GADAdSize) {
    self.adSize = adSize
  }

  func makeUIView(context: Context) -> UIView {
    // Wrap the GADBannerView in a UIView. GADBannerView automatically reloads a new ad when its
    // frame size changes; wrapping in a UIView container insulates the GADBannerView from size
    // changes that impact the view returned from makeUIView.
    let view = UIView()
    view.addSubview(context.coordinator.bannerView)
    return view
  }

  func updateUIView(_ uiView: UIView, context: Context) {
    context.coordinator.bannerView.adSize = adSize
  }

  func makeCoordinator() -> BannerCoordinator {
    return BannerCoordinator(self)
  }
BannerContentView.swift

Per gestire l'inizializzazione e il comportamento del GAMBannerView, crea un Coordinator:

class BannerCoordinator: NSObject, GADBannerViewDelegate {

  private(set) lazy var bannerView: GADBannerView = {
    let banner = GADBannerView(adSize: parent.adSize)
    banner.adUnitID = "ca-app-pub-3940256099942544/2435281174"
    banner.load(GADRequest())
    banner.delegate = self
    return banner
  }()

  let parent: BannerView

  init(_ parent: BannerView) {
    self.parent = parent
  }
BannerContentView.swift

Per ottenere la larghezza della visualizzazione, utilizza GeometryReader. Questa classe calcola le dimensioni appropriate dell'annuncio per l'orientamento corrente del dispositivo. frame è impostato sull'altezza calcolata in base alle dimensioni dell'annuncio.

var body: some View {
  GeometryReader { geometry in
    let adSize = GADCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth(geometry.size.width)

    VStack {
      Spacer()
      BannerView(adSize)
        .frame(height: adSize.size.height)
    }
  }
BannerContentView.swift

Objective-C

Tieni presente che in questo caso non vengono applicati vincoli di larghezza o altezza, in quanto le dimensioni dell'annuncio fornite daranno al banner una dimensione intrinseca dei contenuti per adattarsi alle dimensioni della visualizzazione.
