  • v84.2.0 Changes

    🚀 This minor release adds support for a custom unbounded Ripple radius value. It also includes several 🐛 bug fixes and documentation updates to multiple components.

    🆕 New features

    💅 MDCRippleView now supports a custom ripple radius for the .unbounded ripple style. This allows clients to customize how far outside (or within) a view the ripple effect will extend.

    MDCRippleView *rippleView = [[MDCRippleView alloc] init];
rippleView.rippleStyle = MDCRippleStyleUnbounded;
rippleView.maximumRadius = 10;

    MDCRippleView

    🆕 new property: maximumRadius in MDCRippleView

    ShadowElevations

    MDCShadowElevationNavDrawer

    modified constant: MDCShadowElevationNavDrawer

    Type of change: Declaration
    From: static const MDCShadowElevation MDCShadowElevationNavDrawer = (CGFloat)16.
    To: static const MDCShadowElevation MDCShadowElevationNavDrawer = (CGFloat)4.

  • v84.0.0 Changes

    🚀 This release corrected a TextFields accessibility behavior, added Ripple to Chips, and added ➕ additional delegate calls to BottomSheet.

    🔊 Theming docs for multiple components were added, including Chips, Dialogs, and Cards.

    💥 Breaking changes

    TextField

    The VoiceOver behavior of MDCTextField was modified. Much of the information previously returned by -accessibilityValue is now being returned by -accessibilityLabel. There is now a , that results in a pause between the label and the helper text.

    Searches for MDCTextFields in your view hiearchy with accessiblity value must be changed to searches for the MDCTextField's accessibility label. The label now also has a inserted , too.

    For example an EarlGrey matcher needs to be adjusted from

    EarlGrey
      .selectElement(with: grey_accessibilityValue("Phone Number XXX-XXXX")

    To:

    EarlGrey
      .selectElement(with: grey_accessibilityLabel("Phone Number, XXX-XXXX")

    Bottom Sheet

    All methods in the MDCBottomSheetControllerDelegate protocol were marked optional.

    Two new methods were added to convey state changes and scroll events.

    - (void)bottomSheetControllerDidChangeYOffset:(MDCBottomSheetController *)controller
                                      yOffset:(CGFloat)yOffset {
  NSLog(@"bottom sheet Y offset changed: %f", yOffset);
}

    - (void)bottomSheetControllerStateChanged:(MDCBottomSheetController *)controller
                                    state:(MDCSheetState)state {
  NSLog(@"bottom sheet state changed to: %lu", (unsigned long)state);

  • v82.0.0 Changes

    🚀 In this major release, we dropped support for iOS 8 in all components. We also introduced new method and properties for AppBar, BottomSheet and NavigationDrawer.

    💥 Breaking changes

    🚀 This release drops support for iOS 8 and the library, catalog, examples, and demos may no longer build for iOS 8 targets or may crash even if building succeeds. Clients will need to set their minimum deployment targets to iOS 9 or later.

    🆕 New features

    ➕ Add support for MDCAppBarNavigationController delegate to pick a tracking scroll view

    An optional delegate method was added to allow clients to specify the controller's tracking scroll view. The delegate may return nil if no appropriate tracking scroll view is present.

    Swift

    func appBarNavigationController(_ navigationController: MDCAppBarNavigationController,
                              trackingScrollViewFor trackingScrollViewForViewController: UIViewController,
                              suggestedTrackingScrollView: UIScrollView?) -> UIScrollView? {
  return trackingScrollView
}

    Objective-C

    - (UIScrollView *)appBarNavigationController:(MDCAppBarNavigationController *)navigationController
                  trackingScrollViewForViewController:(UIViewController *)viewController
                          suggestedTrackingScrollView:(UIScrollView *)scrollView {
  return self.trackingScrollView;
}

    flashScrollIndicators in BottomSheet

    MDCBottomSheetController has a new API that will flash the scroll indicators when the view appears.

    Swift

    bottomSheet.shouldFlashScrollIndicatorsOnAppearance = true;

    Objective-C

    self.bottomSheet.shouldFlashScrollIndicatorsOnAppearance = YES;

    maximumInitialDrawerHeight in NavigationDrawer

    Clients can now override the initial drawer height on MDCBottomDrawerViewController with a desired height in points.

    Swift

    bottomDrawer.maximumInitialDrawerHeight = 1000;

    Objective-C

    self.bottomDrawer.maximumInitialDrawerHeight = 1000;

  • v81.1.0 Changes

    🚀 In this minor release we introduced a new beta component, Banner. We also added Ripple support for Buttons, along with text contrast improvements to Tabs and Bottom Navigation.

    🆕 New features

    Ripple integration with Buttons

    ✅ Buttons now support the latest iteration of the Material Design "ripple" effect. Clients can test this functionality by setting enableRippleBehavior to YES.

    Swift

    myButton.enableRippleBehavior = true

    Objective-C

    self.myButton.enableRippleBehavior = YES;

  • v81.0.0 Changes

    🚀 This major release introduces the Ripple component and integrates it with Cards. There are also 👍 visual changes for badges on Tabs, multi-line title support for Bottom Navigation, and improved 👍 Dynamic Type support for Buttons and Feature Highlight.

    💥 Breaking changes

    The appearance of badges on MDCTabBar has changed. Badges now appear similar to those on 0️⃣ MDCBottomNavigationBar and are, by default, a red "pill" shape with white text. The color can be customized by assigning a value to - UITabBarItem.badgeColor.

    🆕 New features

    Ripple integration with Cards

    ✅ Cards now support the latest iteration of the Material Design "ripple" effect. Clients can test this functionality by setting enableRippleBehavior to YES.

    Swift

    myCard.enableRippleBehavior = true

    Objective-C

    self.myCard.enableRippleBehavior = YES;

    👍 Multi-line title support in Bottom Navigation

    👍 Clients can enable multi-line title support in MDCBottomNavigationBar by setting titlesNumberOfLines to a value other than 1. This API should be used only as a last resort, when it is not possible to provide shorter titles that fit within the available screen space.

    Swift

    bottomNavigationBar.titlesNumberOfLines = 0

    Objective-C

    self.bottomNavigationBar.titlesNumberOfLines = 0;

    Automatic Dynamic Type font adjustment in Feature Highlight and Buttons

    👍 Buttons and Feature Highlight now support enabling automatic font size adjustment for Dynamic Type when the fonts used by the components have scaling curves attached using MDCFontScaler. Both components use the new scaling if mdc_adjustsFontForContentSizeCategory is set to YES.

    Swift

    // The new TypographyScheme defaults provide scaled fonts
containerScheme.typographyScheme = MDCTypographyScheme.init(defaults: .material201902)
let button = MDCButton()
button.applyContainedTheme(withScheme: containerScheme)
button.setTitle("Submit", for: UIControlState())
// Enable automatic font adjustment
button.mdc_adjustsFontForContentSizeCategory = true

    Objective-C

    // The new TypographyScheme defaults provide scaled fonts
self.containerScheme.typographyScheme =
    [[MDCTypographyScheme alloc] initWithDefaults: MDCTypographySchemeDefaultsMaterial201804];
MDCButton *button = [[MDCButton alloc] init];
[button applyContainedThemeWithScheme:self.containerScheme];
[button setTitle:@"Submit" forState:UIControlStateNormal];
// Enable automatic font adjustment
button.mdc_adjustsFontForContentSizeCategory = YES;
