檢視 AdMob Mediation Video 的原始碼

首先將AdMob和TAMedia SDK整合至專案中，AdMob SDK可以在這裡下載 '''https://developers.google.com/mobile-ads-sdk/download?#downloadios'''。<br>
接著在AdMob Mediation新增Custom Event（'''https://mediation.admob.com'''）。<br>
新增Custom Event的詳細說明可以參考 '''https://developers.google.com/mobile-ads-sdk/docs/admob/mediation#ios'''。<br>
最後，在專案中加入與Custom Event對應的Class，其中Custom Event的Class Name需要和新增的Class Name保持一致，例如Custom Event的Class Name是TADCustomView，則新增的Class Name也必須為TADCustomView。



== Mediation View Controller ==

 '''// MediationViewController.m'''
 
 - (void)viewWillDisappear:(BOOL)animated {
     '''// MediationViewController 的 view 消失前, 將 _videoView 及其 delegate 設為 nil'''
     '''// _videoView 為 custom 物件呼叫的 TADVideoAdView 物件'''
     '''// 傳回來的 reference 在這裡使用 可以讓 mediation 呼叫的 video 物件跟著 MediationViewController 一起被 dealloc'''
