iAd Banner is not working

Question

I'm trying to get a banner in my app, but since I added the banner, the app won't start.

I get an error saying:

Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named ADBannerView'

Code in .h file:

#import <iAd/iAd.h>

@interface FirstViewController : UIViewController <ADBannerViewDelegate>
{
    ADBannerView *banner;  
}
@property (nonatomic,assign) BOOL bannerIsVisible;
@property (nonatomic,retain) IBOutlet ADBannerView *banner;

Code in .m file:

@synthesize banner, bannerIsVisible;

-(void)bannerViewDidLoad: (ADBannerView *)abanner
{
     if(!self.bannerIsVisible)
     {
         [UIView beginAnimations:@"animatedAdBannerOn" context:NULL];
         banner.frame=CGRectOffset(banner.frame, 0.0, 50.0);
         [UIView commitAnimations];
         self.bannerIsVisible=YES;
     }
}
-(void)bannerView:(ADBannerView *)aBanner
{
     if(!self.bannerIsVisible)
     {
         [UIView beginAnimations:@"animatedAdBannerOff" context:NULL];
          banner.frame=CGRectOffset(banner.frame, 0.0, -320.0);
         [UIView commitAnimations];
         self.bannerIsVisible=NO;
     }
}

What do you think is wrong?

Answer 1

Take this code:

#import <iAd/iAd.h>

@interface ViewController : UIViewController <ADBannerViewDelegate> {
}
@end

.m file:

@implementation ViewController

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

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

You must add iAd.framework into your project.
