在swift中实现unity横幅广告

import UnityAds

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 初始化Unity Ads
        if let unityAdsSDK = UnityAds.sharedInstance() {
            unityAdsSDK.initialize("YOUR_GAME_ID", delegate: self)
        }
    }
    
    func showBannerAd() {
        if let unityAdsSDK = UnityAds.sharedInstance() {
            unityAdsSDK.show(adUnitId: "YOUR_BANNER_AD_UNIT_ID", view: self.view)
        }
    }
}

extension ViewController: UnityAdsDelegate {
    func unityAdsDidInitialize(_ ads: UnityAds, with success: Bool) {
        if success {
            print("Unity Ads initialized successfully")
        } else {
            print("Unity Ads failed to initialize")
        }
    }
    
    func unityAdsDidError(error: Error) {
        print("Unity Ads error: \(error.localizedDescription)")
    }
    
    func unityAdsDidStart(_ adUnitId: String) {
        print("Unity Ads started: \(adUnitId)")
    }
    
    func unityAdsDidFinish(_ adUnitId: String, with finishState: UnityAds.FinishState) {
        print("Unity Ads finished: \(adUnitId), Finish state: \(finishState.rawValue)")
    }
}
