檢視 Mopub Mediation Interstitial 的原始碼

依照[[Mopub Setting|Mopub設定教學]]設定後，開始實做Custom event<br>
官方教學：[https://github.com/mopub/mopub-ios-sdk/wiki/Custom-Events 連結]<br>
1.先建立一class繼承MPInterstitialCustomEvent<br>
2.加入Tamedia TADInterstitial.h<br>
3.複寫<code>-requestInterstitialWithCustomEventInfo:</code>以及在此method內用TADInterstitial呼叫廣告<br>
4.複寫<code>-showInterstitialFromRootViewController:</code>以及在此method內用TADInterstitial的方法<code>-presentFromRootViewController:</code>顯示廣告<br>
5.TADInterstitial的delegate內呼叫MPInterstitialCustomEvent delegate執行對應的method<br>
可參考以下代碼

== CustomInterstitialEvent ==
   #import "MPInterstitialCustomEvent.h"
   #import "TADInterstitial.h"
   
   @interface CustomInterstitialEvent : MPInterstitialCustomEvent <TADInterstitialDelegate>
   
   @property (nonatomic,strong) TADInterstitial *interstitialView;
   
   @end

   #import "CustomInterstitialEvent.h"
   
   @implementation CustomInterstitialEvent
   
   - (void)requestInterstitialWithCustomEventInfo:(NSDictionary *)info {
       TADRequest *request = [TADRequest request];
       
       request.testing = NO;
       // Type: TADGender
       request.gender = kTADGenderUnknown;       
       // Set birthday
       [request setBirthdayWithYear:1988 month:6 day:11];    
       // Set location
       [request setLocationWithLatitude:25.033534 longitude:121.534791 accuracy:1];
       
       // interstitialView 物件初始化
       if (self.interstitialView == nil) {
           self.interstitialView = [[TADInterstitial alloc] init];
       }

       self.interstitialView.delegate = self;
       
       // 設定 AD Unit ID
       NSString *interstitialId = info[@"InterstitialId"];//此處InterstitialId是在Mopub內設定
       self.interstitialView.adUnitID = interstitialId;
       self.interstitialView.turnOnMicrophone = NO;
       
       // 載入廣告
       [self.interstitialView loadRequest:request];

       }
   }
   
   // Interstitial廣告呈現之前呼叫, 注意使用者可能會在廣告內按下連結(網頁, AppStore, ...)而因此離開應用程式, 可以在這function中處理該暫停之項目
   - (void)interstitialWillPresentScreen:(TADInterstitial *)ad {

       }
   }
   
   // Interstitial廣告關閉, 在螢幕上消失之前呼叫, 再次提醒在Interstitail消失前, 必須將Interstitial及delegate設為nil (可以在這個function中執行)
   - (void)interstitialWillDismissScreen:(TADInterstitial *)ad {

       }    
   }
   
   // 使用者在廣告內按下連結(網頁, AppStore, ...)而因此離開應用程式之前呼叫
   - (void)interstitialWillLeaveApplication:(TADInterstitial *)ad {

           [self.delegate interstitialCustomEventWillLeaveApplication:self];
       }
