Theming

MDCAppBarViewController supports Material Theming using a Container Scheme. There are two variants for Material Theming of an AppBar. The Surface Variant colors the App Bar background to be surfaceColor and the Primary Variant colors the App Bar background to be primaryColor.

Swift

// Import the AppBar Theming Extensions module
import MaterialComponents.MaterialAppBar_Theming

...

// Apply your app's Container Scheme to the App Bar controller
let containerScheme = MDCContainerScheme()

// Either Primary Theme
appBarViewController.applyPrimaryTheme(withScheme: containerScheme)

// Or Surface Theme
appBarViewController.applySurfaceTheme(withScheme: containerScheme)

Objective-C

// Import the AppBar Theming Extensions header
#import "MaterialAppBar+Theming.h"

...

// Apply your app's Container Scheme to the App Bar controller
MDCContainerScheme *containerScheme = [[MDCContainerScheme alloc] init];

// Either Primary Theme
[self.appBarController applyPrimaryThemeWithScheme:containerScheme];

// Or Surface Theme
[self.appBarController applySurfaceThemeWithScheme:containerScheme];
