Material Design


Material Theming refers to the customization of your Material Design app to better reflect your product’s brand.

Design documentation


Material Theming is a consistent way to apply a uniform design across your app when using Material Components for iOS. Material Theming on iOS consists of two primary patterns: schemes and themers.

  • Schemes represent your design as systemized symbols.
  • Themers are the glue that apply scheme symbols to components.

For example, there is a scheme for both the Material Design typography system and the Material Design color system. Most components have a themer for at least one of these systems.

Sensible defaults, yet highly configurable

By default, an instance of a scheme is initialized with the Material defaults. You can use these defaults as a baseline, but at a minimum we encourage you to tweak your color scheme’s primary and secondary colors to match your brand colors.



Creating a scheme

In order to access the scheme APIs you’ll first need to add the scheme target to your Podfile:

pod 'MaterialComponents/schemes/Color'
pod 'MaterialComponents/schemes/Typography'

Consider where you will want to store your schemes so that they are accessible by your components. One solution is to have a global singleton that exposes shared scheme instances as we’ve done in the MDCCatalog, but the approach you take should be influenced by your app’s architecture.


import MaterialColorScheme
import MaterialTypographyScheme

let colorScheme = MDCSemanticColorScheme()
let typographyScheme = MDCTypographyScheme()


#import "MaterialColorScheme.h"
#import "MaterialTypographyScheme.h"

MDCSemanticColorScheme *colorScheme = [[MDCSemanticColorScheme alloc] init];
MDCTypographyScheme *typographyScheme = [[MDCTypographyScheme alloc] init];

Applying a scheme

To apply a scheme to a component you must first add the component’s themers to your Podfile. You can see which themers a given component supports by looking at the component’s src/ directory.

pod 'MaterialComponents/AppBar+ColorThemer'
pod 'MaterialComponents/AppBar+TypographyThemer'

You can now access the AppBar themers.


import MaterialComponents.MaterialAppBar_ColorThemer
import MaterialComponents.MaterialAppBar_TypographyThemer

func applyGlobalTheme(to appBar: MDCAppBar) {
  MDCAppBarColorThemer.applySemanticColorScheme(colorScheme, to: appBar)
  MDCAppBarTypographyThemer.apply(typographyScheme, to: appBar)


#import "MaterialAppBar+ColorThemer.h"
#import "MaterialAppBar+TypographyThemer.h"

void ApplyGlobalThemeToAppBar(MDCAppBar *appBar) {
  [MDCAppBarColorThemer applySemanticColorScheme:colorScheme toAppBar:appBar];
  [MDCAppBarTypographyThemer applyTypographyScheme:typographyScheme toAppBar:appBar];
