The header stack view component is a view that coordinates the layout of two vertically stacked bar views.
To add this component to your Xcode project using CocoaPods, add the following to your Podfile
:
pod 'MaterialComponents/HeaderStackView'
Then, run the following command:
pod install
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.
Before using header stack view, you'll need to import it:
import MaterialComponents.MaterialHeaderStackView
#import "MaterialHeaderStackView.h"
Header stack view provides MDCHeaderStackView, which is a UIView subclass.
let headerStackView = MDCHeaderStackView()
MDCHeaderStackView *headerStackView = [[MDCHeaderStackView alloc] init];
You may provide a top bar:
headerStackView.topBar = navigationBar
headerStackView.topBar = navigationBar;
You may provide a bottom bar:
headerStackView.bottomBar = tabBar
headerStackView.bottomBar = tabBar;
