ios - iAd 横幅在 segue 上变白

Question

我正在使用 Xcode 7、Swift 2.0。这个问题既发生在模拟器中，也发生在我在 App Store 上可用的实际应用程序中。很多时候(不总是)，当我在我的应用程序中执行 segue 时，adBanner 在加载新广告之前会变成纯白色。我很困惑，因为有广告可用，即使它是白色的!

这是我的代码:

我初始化 ADBannerView:

var adBanner = ADBannerView(adType: ADAdType.Banner)

在我看来DidLoad:

self.canDisplayBannerAds = true
self.adBanner.delegate = self
self.adBanner.hidden = true
self.adBanner.alpha = 0
self.adBanner.frame.origin.y = self.view.frame.height-self.adBanner.frame.height
self.view.addSubview(self.adBanner)

我的 viewDidDisappear:

override func viewDidDisappear(animated: Bool) {

        super.viewDidDisappear(true)

        adBanner.removeFromSuperview()

        if( deviceType.isEqualToString("iPhone") )
        {

            adBanner.delegate = nil

        }

    }

在我的课上:

    func bannerViewDidLoadAd(banner: ADBannerView!)
    {

        self.adBanner.hidden = false
        UIView.animateWithDuration(0.5, animations: {self.adBanner.alpha = 1})

    }

    func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!)
    {
        self.adBanner.hidden = true
        UIView.animateWithDuration(0.5, animations: {self.adBanner.alpha = 0})

    }

    func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool
    {

        return willLeave

    }

    func bannerViewWillLoadAd(banner: ADBannerView!) {

    }

当使用 Xcode 运行应用程序时，我偶尔会收到此消息，尽管我已经实现了委托(delegate)方法:

ADBannerView:未处理的错误(没有委托(delegate)或委托(delegate)未实现 didFailToReceiveAdWithError:):错误域=ADErrorDomain 代码=5“操作无法完成。横幅 View 可见但没有内容”UserInfo=0x9632d30 {ADInternalErrorCode =5, NSLocalizedFailureReason=横幅 View 可见但没有内容

编辑:问题是使用 canDisplayBannerAds 导致未调用委托(delegate)方法。更多信息在这里:Hiding iAd ADBannerView in Swift when ad fails to load - no delegate or delegate does not implement didFailToReceiveAdWithError

这里有一些适合你的工作代码，对我有用。这不需要 self.candisplaybannerads = true 因为我有一些问题。广告会根据屏幕尺寸自动改变尺寸，位于屏幕底部。在我的 spritekit 游戏中，过渡时变白没有任何问题。

import iAd

class viewController: UIViewController, ADBannerViewDelegate {

var AdBanner = ADBannerView()

override func viewDidLoad() {
    super.viewDidLoad()

        /* Ad Banner Settings */

        AdBanner = ADBannerView()
        AdBanner.frame = CGRectZero
        AdBanner.delegate = self
        self.AdBanner.frame = CGRectMake(0, self.view.frame.size.height-self.AdBanner.frame.size.height, self.AdBanner.frame.size.width, self.AdBanner.frame.size.height)
        AdBanner.backgroundColor = UIColor.clearColor()
        self.view.addSubview(AdBanner)

}

/* All iAd Functions */

func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {
/* whatever you need */
    return true
}

func bannerViewActionDidFinish(banner: ADBannerView!) {
/* whatever you need */
}

func bannerViewDidLoadAd(banner: ADBannerView!) {
    AdBanner.hidden = false
}


func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
    NSLog("Error Loading Ad")
/* whatever you need */
    AdBanner.hidden = true
}
func bannerViewWillLoadAd(banner: ADBannerView!) {
/* whatever you need */
}
