Question

当我按下按钮时，我无法找到正确的解决方案来隐藏我的iAd视图。我喜欢这样的iAd视图：

 -(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];

 }

它完美无缺。但是，如果我不想展示我的iAd视图，我将如何隐藏它？

我在这里寻找答案，但没有直接答案。

如果用户没有互联网连接，则横幅将为空白。当互联网连接不可用时，苹果需要隐藏横幅。

考虑一下你是这样创造的，

- (void)createAdBannerView {
    Class classAdBannerView = NSClassFromString(@"ADBannerView");
    if (classAdBannerView != nil) {
        self.adBannerView = [[[classAdBannerView alloc] 
            initWithFrame:CGRectZero] autorelease];
        [_adBannerView setRequiredContentSizeIdentifiers:[NSSet setWithObjects: 
            ADBannerContentSizeIdentifier320x50, 
            ADBannerContentSizeIdentifier480x32, nil]];
        if (UIInterfaceOrientationIsLandscape([UIDevice currentDevice].orientation)) {
            [_adBannerView setCurrentContentSizeIdentifier:
                ADBannerContentSizeIdentifier480x32];
        } else {
            [_adBannerView setCurrentContentSizeIdentifier:
                ADBannerContentSizeIdentifier320x50];            
        }
        [_adBannerView setFrame:CGRectOffset([_adBannerView frame], 0, 
                -[self getBannerHeight])];
        [_adBannerView setDelegate:self];

        [self.view addSubview:_adBannerView];        
    }
}

调用[self.adBannerView removeFromSuperview];什么时候和你需要隐藏。

@ Matiass21，在这里写下面的代码_bannerIsVisible是bool值而_adBanner是ADBannerView对象。

- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
    if (!_bannerIsVisible)
    {
        // If banner isn't part of view hierarchy, add it
        if (_adBanner.superview == nil)
        {
            [self.view addSubview:_adBanner];
        }

        [UIView beginAnimations:@"animateAdBannerOn" context:NULL];

        // Assumes the banner view is just off the bottom of the screen.
        banner.frame = CGRectOffset(banner.frame, 0, -banner.frame.size.height);

        [UIView commitAnimations];

        _bannerIsVisible = YES;
    }
}

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
    NSLog(@"Failed to retrieve ad");

    if (_bannerIsVisible)
    {
        [UIView beginAnimations:@"animateAdBannerOff" context:NULL];

        // Assumes the banner view is placed at the bottom of the screen.
        banner.frame = CGRectOffset(banner.frame, 0, banner.frame.size.height);

        [UIView commitAnimations];

        _bannerIsVisible = NO;
    }
}

按下按钮隐藏iAd视图
