ABUnknownPersionViewController Regression

Originator:oliver.drobnik
Number:rdar://21438771 Date Originated:18 June 2015
Status:Open Resolved:
Product:iOS SDK Product Version:9.0 (13A4254v)
Classification:Serious Bug Reproducible:Always
 
Summary:
When presenting an ABUnknownPersionViewController on a UINavigationController there are two visual glitches. This is a regression. Running on iOS 8 or built with the iOS 8 SDK these glitches don't occur.

Steps to Reproduce:
1) Run the provided sample app on iOS 9 simulator.
2) Click on the center button


Expected Results:
- the presented view controller should appear, correctly laid out
- just like in iOS 8

Actual Results:
- before any content of the presented view controller appears, there is a black background visible
- after a short pause the content appears
- but it goes behind the navigation bar because it does not obey the topLayoutGuide

Version:
iOS 9.0 (13A4254v)

Notes:
Apparently you changed the internal implementation of ABUnknownPersionViewController to use a controller from the new Contacts framework. Your implementation seem to not take the use case into account which is shown by the sample app.

Configuration:
iPhone 6
