Để sử dụng GADBannerView, hãy tạo 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

Để quản lý quá trình khởi tạo và hành vi của GADBannerView, hãy tạo một 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

Để lấy chiều rộng của thành phần hiển thị, hãy sử dụng GeometryReader. Lớp này tính toán kích thước quảng cáo phù hợp cho hướng thiết bị hiện tại. frame được đặt thành chiều cao được tính từ kích thước quảng cáo.

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

Xin lưu ý rằng trong trường hợp này, chúng tôi không đưa ra giới hạn chiều rộng hoặc chiều cao, vì kích thước quảng cáo đã cho sẽ cung cấp cho biểu ngữ một kích thước nội dung có sẵn để xác định kích thước cho chế độ xem.
