ios - 将UITabBarController的view添加到UIScrollView中，显示不出来，只有黑色。

Question

在做新特性展示的时候，发现网易彩票这种显示完最后一张新特性图片后，可以继续滑动到tabbarcontroller，我试了但把tabBar控制的view添加到ScrollView之后，滑动的时候看到的只是黑色，不知为什么。没有像图片上一样显示了主界面的效果。

Answer 2

How about another way of thinking? It can be understood that this scrollView is a drawer effect

Add scrollView as a child view of keyWindow

You can take a look at my bad code
