底部选项卡栏上方的间隙-嵌入式NavigationController +嵌入式TableViewController

这个问题使我难过了几天。

这是与我相关的情节提要板布局：我将所有阳光视图下的所有布局都设置为所有三个View Controller，并且仍然在“横幅”视图上方获得一个带有“间隙”的结果表视图-看起来与“横幅”视图的高度相同。如下：

起作用的一件事是将容器视图拖动到底部的横幅视图上，如下所示：

结果完美地呈现在我的测试设备以及每个模拟器上-即无间隙。

但是，这样的解决方案本质上是种黑客手段，我想看看是否有什么我可以做的才能正确解决此问题。

For the record, I have tried every option in the IB - adjust scroll view insets, extend edges under top/bottom bars, etc... as well as various code snippets I have googled here and there. Nothing seems to solve the issue for me.

I managed to solve the gap at the top of the table view under the nav bar (seemingly a common issue with a lot of content out there). But there does not seem to be so many cases like mine above.

Any help or indications are greatly appreciated. Thank you people :-)
