如何在madvertise中加载非页内广告？

Question

我已遵循此Link中提供的文档。我正在使用Bridging标头以Swift语言实现它。

Myapp-Bridging-Header.h



 #import "MNGAdsSDKFactory.h"

但是，当我使用方法interstitialAdsFactory.loadInterstitial()展示插页式广告时，出现以下错误：

Value of type 'MNGAdsSDKFactory?' has no member 'loadInterstitial'

这是我的代码，

在viewDidLoad HomeViewController.swift

中呼叫广告广告

func madvertiseInterstitialAd () {

        interstitialAdsFactory = MNGAdsSDKFactory()

        interstitialAdsFactory.interstitialDelegate = self

        interstitialAdsFactory.viewController = self

        interstitialAdsFactory.placementId = String(format: "/%d/%d/interstitial",Constants.kMadvertiseID, Constants.kMadvertisePlacement)

        interstitialAdsFactory.viewController = self

        interstitialAdsFactory.loadInterstitial() // this lines returns error "Value of type 'MNGAdsSDKFactory?' has no member 'loadInterstitial'"

    }
