Question

我正在尝试在我的应用中合并iAdSuite标签栏视图实现，我在套件和我的应用中看到了同样的问题。广告出现后，我的内容视图会正确调整大小并正确显示广告。当广告消失后，它会留下它所在的空白区域。但是，我已经确认我的内容视图确实调整回原来的高度，并将其缩小到原始边界。您无法看到广告所在的部分。我已经确保每个视图都有一个layoutIfNeeded，以及我能想到的其他所有内容都无济于事。有什么想法吗？

编辑：我已经弄清楚问题是什么了。每次调用showBannerView：时，Apple的示例显然会将_bannerView添加到self.view但从不删除视图。由于横幅视图在屏幕外移动，但仍然没有完全合理，但删除它确实解决了空白问题。我的解决方案如下，但如果有人有更优雅的方式，请告诉我。

- (void)layoutAnimated:(BOOL)animated {

    if (UIInterfaceOrientationIsPortrait(self.interfaceOrientation)) {
        _bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
    } else {
        _bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
    }

    CGRect contentFrame = self.view.bounds;
    contentFrame.origin = CGPointMake(0.0, 0.0);
    CGRect bannerFrame = _bannerView.frame;
    if (_bannerView.bannerLoaded) {
        contentFrame.size.height -= _bannerView.frame.size.height;
        bannerFrame.origin.y = contentFrame.size.height;
    } else {
        bannerFrame.origin.y = contentFrame.size.height;
    }

    [UIView animateWithDuration:animated ? 0.25 : 0.0 animations:^{
        _contentView.frame = contentFrame;
        [_contentView layoutIfNeeded];
        _bannerView.frame = bannerFrame;
    }
                     completion:^(BOOL finished) {
                         if (!_bannerView.bannerLoaded) {
                             [_bannerView removeFromSuperview];
                             _bannerView=nil;
                         }
                     }];
}

- (void)showBannerView:(ADBannerView *)bannerView animated:(BOOL)animated
{
    _bannerView = bannerView;
    if (![self.view.subviews containsObject:_bannerView])
        [self.view addSubview:_bannerView];
    [self layoutAnimated:animated];
}

- (void)hideBannerView:(ADBannerView *)bannerView animated:(BOOL)animated
{
    [self layoutAnimated:animated];
}

Answer 1

我遇到了同样的问题。从hideBannerView委托方法中的超级视图中删除bannerview似乎已经解决了它。

- (void)hideBannerView:(ADBannerView *)bannerView animated:(BOOL)animated
{
    [self layoutAnimated:animated];
    [_bannerView removeFromSuperview];
    _bannerView = nil;
}

感谢您提出这个问题和答案，我正在用这个来解决问题。我改变了这个该死的代码，现在隐藏动画正常工作。我想知道苹果为何会发布有缺陷的示例代码...

- (void)layoutAnimated:(BOOL)animated hide:(BOOL)hide
{
    if (UIInterfaceOrientationIsPortrait(self.interfaceOrientation)) {
        _bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
    } else {
        _bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
    }

    CGRect contentFrame = self.view.bounds;


    CGRect bannerFrame = _bannerView.frame;
    if (!hide) {
        contentFrame.size.height -= _bannerView.frame.size.height;
        bannerFrame.origin.y = contentFrame.size.height;
    } else {
        contentFrame.size.height += _bannerView.frame.size.height;
        bannerFrame.origin.y = contentFrame.size.height;
    }

    [UIView animateWithDuration:animated ? 0.25 : 0.0 animations:^{
        _contentView.frame = contentFrame;
        [_contentView layoutIfNeeded];
        _bannerView.frame = bannerFrame;
    } completion:^(BOOL finished) {
        if (hide) {
            [_bannerView removeFromSuperview];
            _bannerView=nil;
        }
    }];
}

- (void)showBannerView:(ADBannerView *)bannerView animated:(BOOL)animated
{
    _bannerView = bannerView;
    [self.view addSubview:_bannerView];
    [self layoutAnimated:animated hide:NO];
}

- (void)hideBannerView:(ADBannerView *)bannerView animated:(BOOL)animated
{
    [self layoutAnimated:animated hide:YES];

}

当广告消失时，iAdSuite错误会留下空白区域
