Hide iAd banner when no ads are available - iphone

Question

This is a Phonegap app. I am completely lost here, please help.
I followed this tutorial to the t.
Here is my MainViewController.m:
- (void)webViewDidFinishLoad:(UIWebView*)theWebView
{
adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
if([UIApplication sharedApplication].statusBarOrientation ==
UIInterfaceOrientationPortrait ||
[UIApplication sharedApplication].statusBarOrientation ==
UIInterfaceOrientationPortraitUpsideDown) {
adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
}
else {
adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
}
adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
CGRect adFrame = adView.frame;
adFrame.origin.y = self.view.frame.size.height-adView.frame.size.height;
adView.frame = adFrame;
[self.view addSubview:adView];
// Black base color for background matches the native apps
theWebView.backgroundColor = [UIColor blackColor];
return [super webViewDidFinishLoad:theWebView];
}

Fast answer:
What you need to do is conform to the ADBannerViewDelegate protocol and hide the ad when it fails to receive an ad.
Step by step version:
In that method you listed, you'll want to also include adView.delegate = self.
In MainViewController.h, where it says #interface MainViewController : UIViewController, you want to add <ADBannerViewDelegate> after, like this:
#interface MainViewController : UIViewController <ADBannerViewDelegate>. If there is already something in < > there, just add a comma and add ADBannerViewDelegate.
Back in the MainViewController.m, add these methods:
- (void)bannerViewDidLoadAd:(ADBannerView *)banner {
adView.hidden = NO;
}
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
adView.hidden = YES;
}
