SDK8 AdMob Mediation Native

簡介

將說明如何將 TAmedia SDK 原生廣告與 Google AdMob 原生廣告(Native advanced)做 mediation 整合，關於 AdMob mediation 請參考：https://developers.google.com/admob/ios/mediate

串接準備

首先先完成 mediation 基本 setup AdMob Mediation Setup, TADCustomEvent 將會透過此客製化 class 取得 TADNativeAd。

實作方式

TADCustomEventNative.swift

import Foundation
import GoogleMobileAds
import TAMediaAdsFramework


class TADCustomEventNative: NSObject {
    var tadNativeAd: TADNativeAd?
    var tadNativeAdView: TADNativeAdView?
    var mappedImages = [GADNativeAdImage]()
    var mapIcon: GADNativeAdImage?
    
    var delegate: GADMediationNativeAdEventDelegate?
    /// Completion handler called after ad load
    var completionHandler: GADMediationNativeLoadCompletionHandler?

    deinit {
        print("TADCustomEventNative - TADMediatedUnifiedNativeAd deinit")
    }
    
    func loadNativeAd(for adConfiguration: GADMediationNativeAdConfiguration,
        completionHandler: @escaping GADMediationNativeLoadCompletionHandler) {
        self.completionHandler = completionHandler
        let request = TADRequest()
        request.showLog = true
        let option = TADNativeAdOptions()
        /// 參見 http://wiki.tamedia.com.tw/iosDoc/Classes/TADNativeAdOptions.html
//        option.disableImageLoading = true //SDK 將不自動下載圖片
//        option.mediaPreferImage = true //只會呈現圖片廣告
//        option.startUnmuted = true     //影片廣告會以非靜音方式呈現
//        option.customControlsRequested = true //自行定義影音廣告的靜音/取消靜音、倒計時標籤和了解更多按鈕
//        option.allowAudioSessionControl = false //設為false則需自行設定影音廣告出現時 AVAudioSession 狀態
