Status:Open Resolved:
Product:iOS Product Version:9.3
Classification:UI/Usability Reproducible:Always
 
Summary:
When presenting a view controller that prefers the status bar hidden over a view controller that prefers the status bar visible, the status bar is hidden/shown without animation.

This is the same the other way around, when presenting a view controller that prefers the status bar visible over a view controller that prefers the status bar hidden.

This has 2 implications:
1. This doesn't look good, the UI looks like it 'jumps'.
2. In custom transitions, calculating view coordinates can be off by the status bar height (+- 20pt).

The issue occurs in iOS 9.3, the status bar animates properly in prior versions.

Steps to Reproduce:
1. Create a view controller that prefers the status bar visible
2. Create a second view controller that prefers the status bar hidden
3. Present one of the 2 view controllers over the other.

Expected Results:
The status bar should hide/show in an animated fashion.

Actual Results:
The status bar hides/shows without animation.
