为什么这个iAd没有正确消失？

Question

// iAd Advertising
#pragma mark iAd Delegate Methods

- (void) bannerViewDidLoadAd:(ADBannerView *)banner {
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1];
    [banner setAlpha:1];
    [UIView commitAnimations];

} // if there is an internet connection, load the iAd with a 1 second fade in effect

- (void) bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1];
    [banner setAlpha:0]; 
    [UIView commitAnimations];
}

When setAlpha is 0 , shouldn't it disappear as opposed to displaying a white line across the screen as a replacement for the ad that isn't there?

I want the banner to completely disappear, but it shows a white banner instead. I've used this type of animating before and had no problem with it making things completely disappear. Is it because it is an iAd banner?

Answer 1

In your header file..

@property (strong, nonatomic) IBOutlet ADBannerView *adBanner;

In your implementation file..

- (void) bannerViewDidLoadAd:(ADBannerView *)banner {
    adBanner.hidden = 0;

}

- (void) bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
    adBanner.hidden = 1;
}

Answer 2

Set your alpha to 0 in your storyboard on the iAd. Then it will work with the code you've provided.
