//用户取消正在执行的广告时 调用
- (void)cancelBannerViewAction {
    NSLog(@"Banner was cancelled!");
    
    self.adStatus.text = @"[iAd]: Bannes was closed.";
}

//苹果公司给你发送一个广告 ! 通过此方法，广告视图ADBannerView 开始显示
//此方法，每间隔一段时间(46秒) 刷新一次
- (void)bannerViewDidLoadAd:(ADBannerView *)banner {
    NSLog(@"[iAd]: Ad did load.");
    self.adStatus.text = @"[iAd]: Ad did load.";
}

//someone 点击了 广告
- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave {
    NSLog(@"[iAd]: An action was started from the banner. Application will quit: %d", willLeave);
    
    self.adStatus.text =[NSString stringWithFormat: @"[iAd]: An action was started from the banner. Application will quit: %d", willLeave];
    
    return YES;
}
//广告执行完成，返回
- (void)bannerViewActionDidFinish:(ADBannerView *)banner {
    NSLog(@"[iAd]: Action finished.");
    
    self.adStatus.text = @"[iAd]: Action finished.";

- (void)bannerView:(ADBannerView *) didFailToReceiveAdWithError:(NSError *)error {
    NSLog(@"[iAd]: Faild to load the banner: %@", error);
    
    self.adStatus.text = [NSString stringWithFormat:@"[iAd]: Faild to load the banner: %@", error];
