v109.3.0

This minor release includes API improvements to ProgressView, SnackBars and TextFields, as well as tests and bug fixes for ActionSheet, AppBar, BottomAppBar, BottomSheet, Collections, Dialogs, FlexibleHeader and Tabs.

New features

ProgressView supports a gradient progress bar:

self.progressView.progressTintColors = @[
  (id)UIColor.greenColor.CGColor, (id)UIColor.blueColor.CGColor, (id)UIColor.redColor.CGColor
];

Snackbars support setting presentation host view on a specific message:

MDCSnackbarMessage *message = [MDCSnackbarMessage messageWithText:@"message"];
message.presentationHostViewOverride = self.collectionView;

Snackbars enable dismissal when the user taps anywhere on the snackbar.

MDCSnackbarMessage *message = [MDCSnackbarMessage messageWithText:@"message"];
message.shouldDismissOnOverlayTap = YES;

TextFields support setting the border radius:

textField.borderRadius = 4.0f;
