ios - UISearchController doesn't work properly with a non-translucent UINavigationBar

Question

Currently I am trying to embed a UISearchController into my application. But the UISearchBar, which is a property of the UISearchController, doesn't get displayed properly, if the UINavigationBar is non-translucent. Usually after tapping the UISearchBar property, the UINavigationBar moves up to make room for the UISearchBar. You can see the result on the following screenshot:

But if the "translucent" property of the UINavigationBar is set to "NO", the UISearchBar doesn't get displayed properly, because the background of the status bar remains transparent, as you can see on the following screenshot:

To demonstrate this weird behaviour, I have modified the sample project provided by Apple:

Here you can download the modified version:

The modification is in file "APLMainTableViewController.m" line 33.

Answer 1

It's clearly a bug (rdar://20942583).

My workaround is to set

self.edgesForExtendedLayout = UIRectEdgeAll;
self.extendedLayoutIncludesOpaqueBars = YES;

This allows you to keep the navigation bar opaque. The downside is that the content flows below the bar even if it can't be seen, creating some overhead.
