Banner delegation

Conform to the RingierAdBannerViewDelegate protocol to receive notifications about the ad's lifecycle. This is essential for handling successful loads, errors, and empty responses.

Ad Loaded Successfully:

func bannerViewAdLoaded(_ view: RingierAdBannerView) {
    print("Banner view has finished loading ad successfully")
}

No Fill:

func bannerViewAdEmpty(_ view: RingierAdBannerView, willWaterfall: Bool, willRefresh: Bool) {
    print("Banner view has finished loading ad with no fill")
}

Ad Loading Failed:

func bannerViewAdFailed(_ view: RingierAdBannerView, error: Error, willWaterfall: Bool, willRefresh: Bool) {
    print("Banner view has finished loading ad with error: \(error)")
}
