ECSlidingViewController与iAds

Question

我正在使用ECSlidingViewController与左侧&右侧菜单。

试图让iAds显示在整个应用程序的底部。我的StoryBoard入口点是一个ViewController，它是一个ECSlidingViewController子类。

故事板设置为AutoLayout以及我所有的其他代码。

当我添加self.canDisplayBannerAds = YES;到viewWillAppear中构建失败：

看起来我需要的地方添加约束的高度都显示网络成瘾者的时候会改变。

Answer 1

首先，在显示视图之前（即视图被加载时）设置为canDisplayBannerAds。

其次，更新视图以便它没有自动转换自动调整大小约束（请参阅translatesAutoresizingMaskIntoConstraints）。

Answer 2

我认为你遇到的问题是你试图调整ECSlidingViewController的子视图的大小。您应该改为调整ECSlidingViewController的视图。

我会创建一个容器视图控制器并将其作为入口点。子视图将是iAd视图和ECSlidingViewController的视图。
