google ima sdk ad loaderがsdkタイムアウトで失敗する

Question

ココアポッド（ポッド 'GoogleAds-IMA-iOS-SDK'、 '〜> 3.2.1'）を使用してGoogle IMA SDKをプロジェクトに統合しました。私はsdkとやりとりするVideoPresenterという別のクラスを持っています。このプレゼンターは、AVPlayerを使用してビデオコンテンツを再生するVideoCellというコレクションビューのセルのプロパティです（このビデオコンテンツにプリロールビデオを追加しようとしています）。広告ローダーは、常に「IMA SDK loading timed out」というエラーメッセージで失敗します。これをどうやって解決するのですか？プレゼンターのコードは次のとおりです。

#import "VideoAdPresenter.h" 
#import <GoogleInteractiveMediaAds/GoogleInteractiveMediaAds.h> 

@interface VideoAdPresenter() <IMAAdsLoaderDelegate,  IMAAdsManagerDelegate> 
@property (nonatomic, strong) IMAAVPlayerContentPlayhead *contentPlayhead; 
@property (nonatomic, strong) IMAAdsLoader *adsLoader; 
@property (nonatomic, strong) IMAAdsManager *adsManager; 

@end 

NSString *const kTestAppAdTagUrl = 
@"https://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/single_ad_samples&ciu_szs=300x250&impl=s&gdfp_req=1&env=vp&output=vast&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ct%3Dlinear&correlator="; 


@implementation VideoAdPresenter 

- (id)initWithAvPlayer:(AVPlayer *)anAvPlayer 
{ 
    self = [super init]; 
    if(self) { 
     self.contentPlayhead = [[IMAAVPlayerContentPlayhead alloc]initWithAVPlayer:anAvPlayer]; 
     [self setupAdsLoader]; 
    } 
    return self; 
}

{ 
    self.adsLoader = [[IMAAdsLoader alloc] initWithSettings:nil]; 
    self.adsLoader.delegate = self; 
}

    if(!self.videoAdTagUrl || [self.videoAdTagUrl isEqualToString:@""]) {

    return; 
} 
    IMAAdDisplayContainer *adDisplayContainer =  [[IMAAdDisplayContainer alloc] initWithAdContainer:self.adContainerView companionSlots:nil]; 
    IMAAdsRequest *request = [[IMAAdsRequest alloc]initWithAdTagUrl:kTestAppAdTagUrl adDisplayContainer:adDisplayContainer contentPlayhead:self.contentPlayhead userContext:nil]; 

    [self.adsLoader requestAdsWithRequest:request]; 
} 

#pragma mark - ads loader delegate

}

    if(self.delegate && [self.delegate respondsToSelector:@selector(videoAdPresenterRequestedContentPause:)]) { 
     [self.delegate videoAdPresenterRequestedContentPause:self]; 
    } 
} 

- (void)adsManagerDidRequestContentResume:(IMAAdsManager *)adsManager { 
    // The SDK is done playing ads (at least for now), so resume the content. 
    if(self.delegate && [self.delegate respondsToSelector:@selector(videoAdPresenterRequestedContentResume:)]) { 
     [self.delegate videoAdPresenterRequestedContentResume:self]; 
    }

理由は、プレゼンターがバックグラウンドスレッドから呼び出されたためです。メインスレッドから同じものを実行することで問題が解決されました。
