尝试将 iAd 移出屏幕时出错
按照 Apple 的要求，尝试在没有加载广告时让 iAds 关闭屏幕。他们给了我这段代码：
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
if (self.bannerIsVisible)
{
[UIView beginAnimations:@"animateAdBannerOff" context:NULL];
// assumes the banner view is at the top of the screen.
banner.frame = CGRectOffset(banner.frame, 0, -50);
[UIView commitAnimations];
self.bannerIsVisible = NO;
}
}
我让我的视图成为 iAds 之类的委托，但每当我尝试编译时，我得到：
"Request for member 'bannerIsVisible' in something not a structure or union
我尝试添加 BOOL BannerIsVisible，但这只会让事情变得更糟
Trying to make iAds go off screen when no ad is loaded, as per Apple's request. They gave me this code:
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
if (self.bannerIsVisible)
{
[UIView beginAnimations:@"animateAdBannerOff" context:NULL];
// assumes the banner view is at the top of the screen.
banner.frame = CGRectOffset(banner.frame, 0, -50);
[UIView commitAnimations];
self.bannerIsVisible = NO;
}
}
I made my view a delegate for iAds and whatnot, but whenever I try to compile, I get:
"Request for member 'bannerIsVisible' in something not a structure or union
I tried adding a BOOL bannerIsVisible, but it just made things worse

要使用
self.bannerIsVisible，您需要将bannerIsVisible声明为属性。To use
self.bannerIsVisibleyou need to havebannerIsVisibledeclared as a property.
