iAd banner在模拟器上接收错误代码7

Question

在模拟器上运行时获取以下日志。

如果我将它发送给Apple，会不会影响我的应用？或者这只是因为它还没有生存？

Appdelegate.swift：

import iAd
var UIiAd: ADBannerView = ADBannerView()
... REST OF BASIC STUF

包含广告的一类（设置）

var UIiAd:ADBannerView = ADBannerView()

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

}

override func viewWillAppear(animated: Bool) {
    UIiAd.delegate = self
    UIiAd = self.appdelegate().UIiAd
    self.tableView.reloadData()
}

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
    UIView.commitAnimations()
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!){
    UIiAd.hidden = true
}
override func viewDidLoad(){
    super.viewDidLoad()
    self.canDisplayBannerAds = true 
}

ADBannerView内显示UINavigationController。
