AdMob Mediation Video

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。

Mediation View Controller

// MediationViewController.h

// 使用 GADInterstitial 物件來介接 TADVideoAdView
@property (nonatomic, strong) GADInterstitial *_adVideo;

// MediationViewController.m

- (void)viewWillDisappear:(BOOL)animated {
    // MediationViewController 的 view 消失前, 將 _adVideo 及其 delegate 設為 nil
    if (_adVideo != nil) {
        _adVideo.delegate = nil;
        _adVideo = nil;
    }
}

Custom Video View

// TADCustomVideo.h

// 匯入 TAMedia SDK 定義
#import "TADVideoAdView.h"

// 匯入 Admob SDK 定義
#import "GADCustomEventBanner.h"

@interface TADCustomVideo : NSObject<GADCustomEventBanner, TADVideoAdViewDelegate>
{
   // 以 instant variable 的方式, 宣告 videoView 物件
    TADVideoAdView *_videoView;
}

@property (nonatomic, weak) id<GADCustomEventBannerDelegate> delegate;

@end

// TADCustomVideo.m

#import "TADCustomVideo.h"

@implementation TADCustomVideo

@synthesize delegate = _delegate;

- (void)requestInterstitialAdWithParameter:(NSString *)serverParameter
                                     label:(NSString *)serverLabel
                                   request:(GADCustomEventRequest *)customEventRequest {
    
    // 將 GADCustomEventRequest 物件裡的資訊轉入 TADRequest 物件
    TADRequest *tadRequest = [TADRequest request];
    tadRequest.testing = customEventRequest.isTesting;
    tadRequest.gender = (TADGender)customEventRequest.userGender;
    tadRequest.birthday = customEventRequest.userBirthday;
    [tadRequest setLocationWithLatitude:customEventRequest.userLatitude longitude:customEventRequest.userLongitude accuracy:customEventRequest.userLocationAccuracyInMeters];

    // videoView 物件初始化
    if (_videoView == nil) {
        _videoView = [[TADVideoAdView alloc] initWithVideoAd];
    }
    
    // 必須要設定delegate
    _videoView.delegate = self;
    
    // serverParameter 為 AD Unit ID, 在 Admob 裡設定
    _videoView.adUnitID = serverParameter;
    
    // 載入廣告
    [_videoView loadRequest:tadRequest];
}

#pragma mark - delegate

- (void)adViewDidReceiveAd:(TADVideoAdView *)view {
    NSLog(@"CustomVideo - adViewDidReceiveAd!!");
    [_delegate customEventInterstitial:self didReceiveAd:view];
}

- (void)adView:(TADVideoAdView *)view didFailToReceiveAdWithError:(NSError *)error {
    NSLog(@"CustomVideo - didFailToReceiveAdWithError!! error: %@", error);
    [_delegate customEventInterstitial:self didFailAd:error];
}

- (void)presentFromRootViewController:(UIViewController *)rootViewController{
    // 介接 TADVideoAdView 不需要 presentFromRootViewController
}

- (void)dealloc {
    NSLog(@"CustomVideo - dealloc!!");
    // Custom物件消失前, 要將 videoView 及其 delegate 設為 nil
    if (_videoView) {
        _videoView.delegate = nil;
        _videoView = nil;
    }
