ADBannerView问题

Question

我对我所有的这些代码viewcontroller页来控制我的AdBanner多个页面。 它可以在我的应用程序的最新版本上正常工作，但是由于某些原因，我正在使用此更新，因此我认为我的应用程序没有调用bannerViewDidLoadAd或didFailToReceiveAdWithError函数。 当我频繁地更改页面时，也会出现此错误。 `

“警告：当前存在10个以上的ADBannerView或ADInterstitialView实例。这是iAd API的滥用，因此广告性能会受到损害。此消息仅打印一次。”

`我有什么想念的吗？ 谢谢

// Ad controller

var UIiAd: ADBannerView = ADBannerView()
var screenHeight = UIScreen.mainScreen().bounds.height
var adBannerHeight: CGFloat = 50
@IBOutlet var constOne: NSLayoutConstraint!

func appdelegate() -> AppDelegate {
    return UIApplication.sharedApplication().delegate as! AppDelegate
}

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

func bannerViewDidLoadAd(banner: ADBannerView!) {
    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1)
    UIiAd.alpha = 1
    adBannerHeight = 50
    UIView.commitAnimations()
    constOne.constant = 58
    print("ad loaded")
}

func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1)
    UIiAd.alpha = 0
    adBannerHeight = 0
    UIView.commitAnimations()
    constOne.constant = 8
    print("error")
}

override func viewWillAppear(animated: Bool) {
    UIiAd.delegate = self
    UIiAd = self.appdelegate().UIiAd
    UIiAd.frame = CGRectMake(0, screenHeight - adBannerHeight , 0, 0)
    self.view.addSubview(UIiAd)

}

// End of Ad Controller

尝试更改此代码：

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

至：

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