Material Components for iOS v107.2.0 Release Notes

• 🚀 This minor release includes the introduction of a self-sizing mechanism to MDCBaseCell, a new layout style for MDCTabBarView, and numerous improvements and bug fixes for BottomSheet, Snackbar, Dialogs, Ink, and TextFields.

  🆕 New features

  List

  🛠 Having the UICollectionViewLayoutAttributes you use with MDCBaseCell conform to MDCSelfSizingLayoutAttributes allows you to specify whether the height or the width should be fixed.

  -(BOOL)isFixedWidth {
    return 100;
  }
  
  -(BOOL)isFixedHeight {
    return 100;
  }
  

  var isFixedWidth: Bool {
    return 100;
  }
  
  var isFixedHeight: Bool {
    return 100;
  }
  

  Tabs

  💅 Setting the preferredLayoutStyle property on MDCTabBarView to MDCTabBarViewLayoutStyleScrollableCentered allows you to have a scrolling tab bar that centers the selected tab.

  tabBarView.preferredLayoutStyle = MDCTabBarViewLayoutStyleScrollableCentered;
  

  tabBarView.preferredLayoutStyle = .scrollableCentered
