试图在测试应用程序中包含广告。横幅通常显示,但是从控制器转换,其中在另一个控制器上有广告,在系统输出中显示奇怪的信息:
[AppDeveloper] ADBannerView: Unhandled error (no delegate or delegate does not implement didFailToReceiveAdWithError:): Error Domain=ADErrorDomain Code=7 "The operation couldn’t be completed. Ad was unloaded from this banner" UserInfo=0x7cd27d80 {ADInternalErrorCode=7, ADInternalErrorDomain=ADErrorDomain, NSLocalizedFailureReason=Ad was unloaded from this banner}
更新:当app启动时,在系统输出中显示以下信息:
<Error>: CGAffineTransformInvert: singular matrix.
但应用程序仍然正常工作........
我在iAd控制器中的代码:
@IBOutlet var adBannerCurrentCity: ADBannerView
override func viewDidLoad() {
super.viewDidLoad()
self.canDisplayBannerAds = true
self.adBannerCurrentCity.delegate = self
self.adBannerCurrentCity.hidden = true
}
func bannerViewDidLoadAd(banner: ADBannerView!) {
self.adBannerCurrentCity.hidden = false
}
func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {
return willLeave
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
self.adBannerCurrentCity.hidden = true
}
有什么问题?
