更改UISearchController的UINavigationBar背景颜色

Question

At the minute, my search controllers "navigation bar" background is the standard default translucent however, all the other bars in my app are black translucent. When I print the navigationController property of the searchController, it returns nil and so does the navigationBar, but not the navigationItem. There are no other public properties that seem to let you change the color of the bar. I don't mind overriding private ivars as I wont be releasing this app on the app store.

您可以使用barTintColor属性，在Swift中将是：

searchBar.barTintColor = UIColor.redColor()
