首先，需要在项目中包含MoPubUnity.unitypackage，包的下载地址：
https://github.com/mopub/mopu...

接下来点击菜单Assets->Import Package->Custom Package，选择包文件

至此包就被包含进去了，包里面有简单的使用用例，不过不适合直接接入项目中。我们还是要写一个新的Controller来处理广告相关的事务。

新的Controller在本文中被命名为 MopubAdsController，首先将广告id暴露到Inspector界面： 
    #region Inspector Variables            [SerializeField] private string iOSBannerID;            [SerializeField] private string iOSInterstitialID;            [SerializeField] private string iOSVideoID;            [Space]            [SerializeField] private string AndroidBannerID;            [SerializeField] private string AndroidInterstitialID;            [SerializeField] private string AndroidVideoID;    #endregion

由于广告请求的函数的参数不是string，而是string数组，所以需要另三个函数来承接上面的id

    private string[] _bannerAdUnits;    private string[] _interstitialAdUnits;    private string[] _rewardedVideoAdUnits;

接下来进入Start函数：

    void Start()            {    #if UNITY_IOS                _bannerAdUnits = new string[] {iOSBannerID};                _interstitialAdUnits = new string[] { iOSInterstitialID };                _rewardedVideoAdUnits = new string[] { iOSVideoID };        #elif UNITY_ANDROID || UNITY_EDITOR                    _bannerAdUnits = new string[] {AndroidBannerID};                _interstitialAdUnits = new string[] { AndroidInterstitialID };                _rewardedVideoAdUnits = new string[] { AndroidVideoID };        #endif                    var anyAdUnitId = _bannerAdUnits[0];                MoPub.InitializeSdk(new MoPub.SdkConfiguration                {                    AdUnitId = anyAdUnitId,                    LogLevel = MoPubBase.LogLevel.MPLogLevelDebug,                    MediatedNetworks = new MoPub.MediatedNetwork[]                    {                    },                });                    MoPub.LoadBannerPluginsForAdUnits(_bannerAdUnits);    #if UNITY_IOS                MoPub.CreateBanner(_bannerAdUnits[0], MoPubBase.AdPosition.BottomCenter);    #elif UNITY_ANDROID                MoPub.CreateBanner("REPLACE_BY_ANDROID_AD_UNIT_ID_HERE", MoPubAdPosition.BottomCenter );    #endif                    MoPub.LoadInterstitialPluginsForAdUnits(_interstitialAdUnits);                MoPub.RequestInterstitialAd(_interstitialAdUnits[0]);                    MoPub.LoadRewardedVideoPluginsForAdUnits(_rewardedVideoAdUnits);                        //初始化各种广告,现在还没有使用好几个id的需求，所以每个广告类型先都用一个id，所以都取[0]。按着官方用例，如果有多种id的话可以写一个for循环直接遍历创造就好                            //以下是各种回调的承接，相当于OC的XX.delegate = self；                    MoPubManager.OnSdkInitializedEvent += OnSdkInitializedEvent;                    MoPubManager.OnAdLoadedEvent += OnAdLoadedEvent;                MoPubManager.OnAdFailedEvent += OnAdFailedEvent;                    MoPubManager.OnInterstitialLoadedEvent += OnInterstitialLoadedEvent;                MoPubManager.OnInterstitialFailedEvent += OnInterstitialFailedEvent;                MoPubManager.OnInterstitialDismissedEvent += OnInterstitialDismissedEvent;                    MoPubManager.OnRewardedVideoLoadedEvent += OnRewardedVideoLoadedEvent;                MoPubManager.OnRewardedVideoFailedEvent += OnRewardedVideoFailedEvent;                MoPubManager.OnRewardedVideoFailedToPlayEvent += OnRewardedVideoFailedToPlayEvent;                MoPubManager.OnRewardedVideoClosedEvent += OnRewardedVideoClosedEvent;            }

其中：

MoPubManager.OnSdkInitializedEvent += OnSdkInitializedEvent;

是C#的回调承接方法。其中OnSdkInitializedEvent是一个回调方法

 private void OnSdkInitializedEvent(string adUnitId){    //_demoGUI.SdkInitialized();}

而MoPubManager.OnSdkInitializedEvent则可以看做是一个装方法类型的数组，每当时间发生时，此数组中的方法会被依次调用，这也就是C#的回调原理。

接下来是Controller的public函数，供给外部调用，外部想显示广告只要调用响应函数就可以了

        public void ShowBannerAd()        {            MoPub.ShowBanner(_bannerAdUnits[0], true);        }        public void HideBannerAd()        {            MoPub.ShowBanner(_bannerAdUnits[0], false);        }        public void OnAdLoadedEvent(string adUnitId, string height)        {        }        public bool ShowInterstitial()        {            bool show = false;            Debug.Log("mopub调试——interstitial尝试播放");            if (MoPub.IsInterstitialReady(_interstitialAdUnits[0]))            {                MoPub.ShowInterstitialAd(_interstitialAdUnits[0]);                show = true;                Debug.Log("mopub调试——interstitial播放");            }            else            {                MoPub.RequestInterstitialAd(_interstitialAdUnits[0]);                Debug.Log("mopub调试——interstitial未加载成功，重新加载");            }            return show;        }

接下来是各种回调函数

  //-----------------------回调-------------------------------------------        //SDK初始化成功        private void OnSdkInitializedEvent(string adUnitId)        {        }        // Banner Events        //banner读取成功        private void OnAdLoadedEvent(string adUnitId, float height)        {            Debug.Log("mopub调试——banner读取成功");        }        //banner读取失败        private void OnAdFailedEvent(string adUnitId, string error)        {            Debug.Log("mopub调试——banner读取失败, id:" + adUnitId);        }        // Interstitial Events        //interstitial读取成功        private void OnInterstitialLoadedEvent(string adUnitId)        {            Debug.Log("mopub调试——interstitial读取成功");        }        //interstitial读取失败        private void OnInterstitialFailedEvent(string adUnitId, string error)        {            MoPub.RequestInterstitialAd(_interstitialAdUnits[0]);            Debug.Log("mopub调试——interstitial读取失败, id:" + adUnitId);        }        //interstitial关闭        private void OnInterstitialDismissedEvent(string adUnitId)        {            MoPub.RequestInterstitialAd(_interstitialAdUnits[0]);            Debug.Log("mopub调试——interstitial关闭");        }
