Overview

This view's sole purpose is to facilitate the relative layout of two horizontal bars. The bottom bar will bottom align and be of fixed height. The top bar will stretch to fill the remaining space if there is any.

The top bar is typically a navigation bar. The bottom bar, when provided, is typically a tab bar.

Usage

Importing

Before using Header Stack View, you'll need to import it:

Header Stack View provides MDCHeaderStackView, which is a UIView subclass.

Swift

let headerStackView = MDCHeaderStackView()

Objective-C

MDCHeaderStackView *headerStackView = [[MDCHeaderStackView alloc] init];

You may provide a top bar:

You may provide a bottom bar:

Swift

headerStackView.bottomBar = tabBar

Objective-C

headerStackView.bottomBar = tabBar;
