Material Components for iOS v113.1.0 Release Notes

• 🚀 In this minor release we have added a ScalableFontDescriptor library to represent custom scalable fonts from iOS 11 and up, added UILargeContentViewer support to AppBar, NavigationBar, TabBarView, as well as other improvements.

  🆕 New deprecations

  • 🗄 We have deprecated some MDCSnackbarManager class methods. Please use MDCSnackbarManager.defaultManager and their corresponding instance methods instead.

  🆕 New features

  On iOS 11 and up, using ScalableFontDescriptor enables you to describe a custom font and the corresponding UIFontMetrics that enable the font to scale in response to Dynamic Type settings. This type enables you to pair font descriptors with specific UIFontMetrics. This is most commonly used for describing the metrics of a collection of custom fonts.

  // Create the type scale.
  let fontDescriptor = UIFontDescriptor(name: "CustomFont-Light", size: UIFont.labelFontSize)
  let scalableFontDescriptor: MDCScalableFontDescriptor
  if #available(iOS 11, *) {
   scalableFontDescriptor = MDCScalableFontDescriptor(
     fontDescriptor: fontDescriptor,
     fontMetrics: UIFontMetrics(forTextStyle: .largeTitle)
   )
  } else {
   scalableFontDescriptor = MDCScalableFontDescriptor(fontDescriptor: fontDescriptor)
  }
  // Use the scalable font descriptor.
  if #available(iOS 11, *) {
   label.font = scalableFontDescriptor.preferredFont(compatibleWith: label.traitCollection)
   label.adjustsFontForContentSizeCategory = true
  } else {
   label.font = scalableFontDescriptor.baseFont()
  }
  

  You can now toggle if you would like that your BottomDrawer will display at fullscreen or not when in mobile landscape by setting the shouldDisplayMobileLandscapeFullscreen property on MDCBottomDrawerViewController.

  let controller = MDCBottomDrawerViewController()
  controller.shouldDisplayMobileLandscapeFullscreen = false
