v93.3.0

This minor release adds two new APIs to FlexibleHeader for contexts involving multiple tracking
scroll views (such as tabbed interfaces).

New features

MDCFlexibleHeaderView has a new API,
allowShadowLayerFrameAnimationsWhenChangingTrackingScrollView, that can be used to enable shadow
layer frame animations when the header's height is animated after switching to a new tracking
scroll view. This flag is false by default, but will be enabled and then deleted in the future, so
please consider enabling it wherever you instantiate a flexible header or app bar.

MDCFlexibleHeaderView has a new animationDelegate API that can be used to react to the completion
of the animation that occurs when changing tracking scroll views.

Component changes

FlexibleHeader

• Add behavioral flag for animating shadow layer frames when tracking scroll view is changed (#8715) (featherless)
• Expose an animation delegate on MDCFlexibleHeaderView. (#8712) (featherless)

v93.2.0

In this minor release TextFields support multiline error/helper text, FeatureHighlight supports Dynamic Type, OverlayWindow supports iOS 13 UIWindow scene initializer API, along with a PageControl dot placement fix, and additional component testing.

New features

FeatureHighlight

You can now set adjustsFontForContentSizeCategory on MDCFeatureHighlightViewController to automatically update your scalable font when content size category changes.
Namely, when adjustsFontForContentSizeCategory is set to YES the title and body fonts will scale appropriately if given a scalable font.

OverlayWindow

MDCOverlayWindow now supports being initialized with initWithWindowScene: as part of the new UIWindow iOS 13 APIs.

TextFields

MDCTextField now supports multiline error and helper texts. To set this up you will need to change the number of lines and word wrapping of the label:

MDCTextField *textField = [[MDCTextField alloc] init];
textField.leadingUnderlineLabel.numberOfLines = 0;
textField.leadingUnderlineLabel.lineBreakMode = NSLineBreakByWordWrapping;

  // Perform button customization
}

New features

MDCTextInputControllerOutlinedTextArea now allows users to specify minimumLines and expandsOnOverflow.

MDCTextInputControllerOutlinedTextArea *textInputControllerOutlinedTextArea =
    [[MDCTextInputControllerOutlinedTextArea alloc] initWithTextInput:self.textField];
textInputControllerOutlinedTextArea.minimumLines = 1;
textInputControllerOutlinedTextArea.expandsOnOverflow = YES;

Swift

let textInputControllerOutlinedTextArea =
    MDCTextInputControllerOutlinedTextArea(textInput: textField)
textInputControllerOutlinedTextArea.minimumLines = 1
textInputControllerOutlinedTextArea.expandsOnOverflow = true

MDCBottomDrawerPresentationControllerDelegate has new methods that allow clients to respond to animation lifecycle events and touches to the scrim.

Touch events set to delegate

Touch events are propagated to delegate to allow clients to interpret touches in the scrim area.

Objective-C

navigationDrawer.dismissOnBackgroundTap = NO;
navigationDrawer.shouldForwardTouchEvents = YES;
...
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}
- (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}

Swift

navigationDrawer.dismissOnBackgroundTap = false
navigationDrawer.shouldForwardTouchEvents = true
...
override public func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
}
public override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
}

Animation events sent to delegate

The animation lifecycle events are forwarded to the delegate so that clients can respond to them.

Objective-C

- (void)bottomDrawerControllerWillTransitionOpen:(nonnull MDCBottomDrawerViewController *)controller
                                 withCoordinator:
                                     (nullable id<UIViewControllerTransitionCoordinator>)
                                         transitionCoordinator
                                   targetYOffset:(CGFloat)targetYOffset {
}

- (void)bottomDrawerControllerDidEndOpenTransition:(MDCBottomDrawerViewController *)controller {
}

- (void)
    bottomDrawerControllerWillTransitionClosed:(nonnull MDCBottomDrawerViewController *)controller
                               withCoordinator:(nullable id<UIViewControllerTransitionCoordinator>)
                                                   transitionCoordinator
                                 targetYOffset:(CGFloat)targetYOffset {
}

- (void)bottomDrawerControllerDidEndCloseTransition:(MDCBottomDrawerViewController *)controller {
}

- (void)bottomDrawerControllerDidChangeTopYOffset:
            (nonnull MDCBottomDrawerViewController *)controller
                                          yOffset:(CGFloat)yOffset {
}

Swift

public func bottomDrawerControllerWillTransitionOpen(_ controller: MDCBottomDrawerViewController, with transitionCoordinator: UIViewControllerTransitionCoordinator?, targetYOffset:CGFloat) {
}

public func bottomDrawerControllerDidEndOpenTransition(_ controller: MDCBottomDrawerViewController) {
}

public func bottomDrawerControllerWillTransitionClosed(_ controller: MDCBottomDrawerViewController, with transitionCoordinator: UIViewControllerTransitionCoordinator?) {
}

public func bottomDrawerControllerDidEndCloseTransition(_ controller: MDCBottomDrawerViewController) {
