Question

我正在将app中的iAd加载到app delegate中。它加载正常但在视图控制器中，它不会显示。我在应用委托代理中的代码来声明广告 var UIiAd: ADBannerView = ADBannerView() 我在视图控制器中的代码是

class HelpViewController: UIViewController, ADBannerViewDelegate {
    //MARK: - Properties
    var UIiAd: ADBannerView = ADBannerView()
    //MARK: - did something
    override func viewDidLoad() {
        super.viewDidLoad()


        // Do any additional setup after loading the view.
    }

    override func viewWillAppear(animated: Bool) {
        //super.viewWillAppear(animated)
        let ScreenHeight = UIScreen.mainScreen().bounds.height

        UIiAd.delegate = self
        UIiAd = self.appDelegate().UIiAd
        UIiAd.frame = CGRectMake(0, ScreenHeight - 50, 0, 0)
        UIiAd.hidden = true
        self.view.addSubview(UIiAd)
    }

    override func viewWillDisappear(animated: Bool) {
        UIiAd.delegate = nil
        UIiAd.removeFromSuperview()
    }



    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    //MARK: - iAd
    func bannerViewDidLoadAd(banner: ADBannerView!) {
        UIView.beginAnimations(nil, context: nil)
        UIView.setAnimationDuration(1)
        UIiAd.hidden = false
        UIView.commitAnimations()
        print("Did load ad")
    }

    func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
        UIView.beginAnimations(nil, context: nil)
        UIView.setAnimationDuration(0)
        UIiAd.hidden = true
        UIView.commitAnimations()
        print("Did fail to receive ad with error \(error)")
    }

    //MARK: - Functions
    func appDelegate() -> AppDelegate {
        return UIApplication.sharedApplication().delegate as! AppDelegate
    }
}

似乎问题是，bannerViewDidLoadAd并没有被调用。如果它加载，我将如何取消隐藏横幅？

我实际已经解决了这个问题。你需要在app委托中做什么 class AppDelegate: UIResponder, UIApplicationDelegate, ADBannerViewDelegate 然后你想制作一个在广告加载时改变的布尔值然后你想添加函数func bannerViewDidLoadAd(banner: ADBannerView!) { adLoaded = true } 这将更改广告加载时的值然后在你想要的视图控制器中

override func viewWillAppear(animated: Bool) {
    //super.viewWillAppear(animated)
    let ScreenHeight = UIScreen.mainScreen().bounds.height

    UIiAd.delegate = self
    UIiAd = self.appDelegate().UIiAd
    UIiAd.frame = CGRectMake(0, ScreenHeight - 50, 0, 0)
    canDisplayBannerAds = true
    if appDelegate().adLoaded == true {
    self.view.addSubview(UIiAd)
    }
}

如果广告未加载，则会将广告添加到您的视图控制器
