iAd横幅视图委托不调用方法 [英] iAd Banner View Delegate Not Calling Methods

问题描述

我有一个iAd横幅视图，所有合同都已启动并运行，并且已经实现了ADBannerView委托.标语应在没有互联网连接的情况下消失，但仅在内容应显示的地方显示一个白框.我知道我所有的代码都正确，我已经看过一百万本教程.因此，我进行了一些测试，发现横幅视图甚至都没有为委托调用这两种方法！这是代码.

I have an iAd banner view, with all my contracts up and running, and I've implemented the ADBannerView delegate. The banner should disappear with no internet connection, but it just shows a white box where the content should be. I know I have all the code right, I've seen a million tutorials on this. So I ran some tests and found that the banner view wasn't even calling the two methods for the delegate! Here is the code.

在.h文件中:

#import <iAd/iAd.h>

@interface DetailViewController : ADBannerViewDelegate>
{
    ADBannerView *aBanner;
    BOOL bannerIsVisible;
}

@property (nonatomic, retain) IBOutlet ADBannerView *aBanner;
@property (nonatomic, assign) BOOL bannerIsVisible;

@end

在.m文件中:

@implementation DetailViewController

@synthesize aBanner,bannerIsVisible;

//Show banner if can load ad.
-(void)bannerViewDidLoadAd:(ADBannerView *)banner
      { 
         if (!self.bannerIsVisible) { 
            [UIView beginAnimations:@"animateAdBannerOn" context:NULL]; banner.frame = CGRectOffset(banner.frame, 0, -banner.frame.size.height); 
            [UIView commitAnimations]; self.bannerIsVisible = YES; }
      }

    //Hide banner if can't load ad.
    -(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
    { 
        if (self.bannerIsVisible) { 
            [UIView beginAnimations:@"animateAdBannerOff" context:NULL]; banner.frame = CGRectOffset(banner.frame, 0, banner.frame.size.height);           
            [UIView commitAnimations]; self.bannerIsVisible = NO; }
    }

推荐答案

您必须将标题委托设置为文件所有者.我遇到了同样的问题，把头撞在墙上之后，事情就这么简单了.

You have to set the banner delegate to files owner. I had the same issue and after beating my head against the wall it was that simple.
