test case

1. Set UILabel.Appearance properties
2. Create a UILabel and add it to the view hierarchy

Actual Results:

Appearance properties that were set have no effect.

UILabel should appear on screen with with a visual appearance as per the properties set on UILabel.Appearance

I'm running version 6.0.6

I do not think it's an XI issue. Part of the issue is the lack of UI_APPEARANCE_SELECTOR on UILabel [1], i.e. TextColor is not decorated.

BackgroundColor really exist in UIView (not UILabel) but it was not decorated with UI_APPEARANCE_SELECTOR (before 7.0). Not sure why it still fails.

OTOH we know that UI_APPEARANCE_SELECTOR is not always required (and that's why we have some extra API on Appearance). Also it seems this works (at least for some people) when using NIB. Not sure why, maybe different code paths in iOS? There's much undocumented behaviour behind appearance :-(

I can reproduce the same behavior with an Xcode project, so this is not an XI issue.
