ADBannerView问题

Question

我在所有viewcontroller页面上都有此代码，可以跨多个页面控制我的AdBanner。它在我的应用程序的最后一个版本上正常工作，但由于某些原因，我正在努力，我不认为我的应用程序正在调用bannerViewDidLoadAd或didFailToReceiveAdWithError函数。此外，当我更改页面时，我收到此错误。 `

  

“警告：ADBannerView或ADInterstitialView的实例超过10个   目前存在。这是对iAd API和广告效果的误用   结果会受到影响。此消息仅打印一次。“

`我有什么遗失的东西吗？感谢

// 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()
}

要：

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