AdMob Mediation

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。
接著在AdMob Mediation新增Custom Event（https://mediation.admob.com）。
新增Custom Event的詳細說明可以參考https://developers.google.com/mobile-ads-sdk/docs/admob/mediation#ios。
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。
