如何检测用户何时在Swift iOS中删除插页式广告？

Question

I'm showing GADInterstitialAd in my iOS app using present in Swift. Below is the code I'm using to show ad.

func showAd() {
    if self.interstitialAd.isReady {
        self.interstitialAd.present(fromRootViewController: self)
    }
}

I'm running a timer on screen which I want to pause and resume once the ad is dismissed off the screen. Can anybody tell me how to implement this? I checked interstitialWillDismissScreen but seems like for that I need to have my custom class derived from GADInterstitialDelegate . As of now I'm directly using var interstitialAd: GADInterstitial! and I'm wondering if there is any way I can just check when Ad is on and off the screen?

You need to include GADInterstitialDelegate in your class. There is no other way to check if the ad is on screen.

class ViewController: UIViewController, GADInterstitialDelegate {

    var interstitial: GADInterstitial!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Setup interstitial here
        // Set its delegate
        interstitial.delegate = self
    }

    func interstitialWillPresentScreen(_ ad: GADInterstitial) {
        print("Ad presented")
    }

    func interstitialDidDismissScreen(_ ad: GADInterstitial) {
        // Send another GADRequest here
        print("Ad dismissed")
    }
}
