Continue to iOS dev publishing same clustering convenience class as before for Android Android AdMob Native ads convenience class:
let adUnitID = "ca-app-pub-blah"
final class AdmobData: NSObject, ObservableObject, GADAdLoaderDelegate, GADUnifiedNativeAdLoaderDelegate {
let loadSize = 3
let minSize = 2
var adLoader: GADAdLoader? = nil
@Published var adsMapping: [Int: GADUnifiedNativeAd] = [:]
var adsBacklog = Set<Int>()
var adsCache: [GADUnifiedNativeAd] = []
func flush() {
for (_, nativeAd) in adsMapping {
adsCache.append(nativeAd)
}
adsMapping.removeAll()
}
func setAd(hash: Int) {
if adsMapping[hash] == nil {
if (adsCache.count < minSize || adsBacklog.count > 0) {
load();
}
if adsCache.isEmpty {
// If no ads in cache wait for
// it and put task in backlog
adsBacklog.insert(hash);
} else {
// otherwise get ad from cache
adsMapping[hash] = adsCache.popLast()
}
}
}
func load() {
if adLoader == nil {
let multipleAdsOptions = GADMultipleAdsAdLoaderOptions()
multipleAdsOptions.numberOfAds = loadSize
adLoader = GADAdLoader(adUnitID: adUnitID, rootViewController: nil,
adTypes: [ .unifiedNative ], options: [multipleAdsOptions])
}
adLoader?.delegate = self
// DispatchQueue.global(qos: .userInitiated).async { [weak self] in
if !(adLoader?.isLoading ?? false) {
adLoader?.load(GADRequest())
}
// }
}
func adLoader(_ adLoader: GADAdLoader, didReceive nativeAd: GADUnifiedNativeAd) {
// print("adLoader")
if adsBacklog.isEmpty {
adsCache.append(nativeAd);
} else {
// POP
let hash = adsBacklog.popFirst()
if hash != nil {
self.adsMapping[hash!] = nativeAd
}
/*
if (!adLoader.isLoading()) {
load();
}
*/
}
}
func adLoader(_ adLoader: GADAdLoader, didFailToReceiveAdWithError error: GADRequestError) {
print("\(adLoader) failed with error: \(error.localizedDescription)")
}
}
struct AdmobNativeAd: View {
@EnvironmentObject var admobData: AdmobData
let id: Int
var body: some View {

.cornerRadius(10)
}
Text(self.admobData.adsMapping[id]?.headline ?? "")
}
.frame(minHeight: 100)
.onAppear() {
self.admobData.setAd(hash: self.id)
}
}
}
struct AdmobNativeAd_Previews: PreviewProvider {
static var previews: some View {
AdmobNativeAd(id: 0)
}
}
What people think about it? Is it useful or better to use google's example? Used it in anonymous chat app https://apps.apple.com/us/app/lonje-anonymous-chat/id1215525783?ls=1 and it looks natural versus google native example.
