ios7 status bar color during push animation

ios7 status bar color during push animation

My app has a solid gray navigation bar, and to fit with the ios7 design,
want the status bar to be the same color. To do this, I've set
edgesForExtendedLayout = UIRectEdgeNone and
extendedLayoutIncludesOpaqueBars = YES and have View controller-based
status bar appearance set to YES in my plist. To create the gray color for
the status bar, I've set the background color of my MainWindow to be the
gray color. This works well except when there's a push or pop animation.
During the animation, the status bar flashes color and looks like it has
double the intensity of gray. When the animation ends, it changes back to
the correct gray color.
Does anyone know what might be happening? Should I be setting the status
bar color to match the navigation bar color differently?
