To imitate the style and animations of the Apple TV app in a custom navigation bar in SwiftUI for iOS 16, you can follow the steps below:
NavigationView
initializer and passing your root view as the content parameter.NavigationView {
// your root view goes here
}
UINavigationBarAppearance
initializer and setting its properties..init(
backgroundColor: UIColor.systemBackground,
titleTextAttributes: [.foregroundColor: UIColor.label],
largeTitleTextAttributes: [.foregroundColor: UIColor.label]
)
In the example above, we're setting the background color of the navigation bar to the system's background color, and the text color of the title and large title to the label color. You can customize these properties further to give the navigation bar a unique look.
SearchBar
view and embedding it in a SearchBarWrapper
view, as shown below.struct SearchBarWrapper: View {
@Binding var text: String
var body: some View {
HStack {
SearchBar(text: $text)
Button(action: {
// handle cancel button
}) {
Text("Cancel")
}
}
}
}
struct SearchBar: UIViewRepresentable {
@Binding var text: String
func makeUIView(context: Context) -> UISearchBar {
let searchBar = UISearchBar(frame: .zero)
searchBar.delegate = context.coordinator
searchBar.showsCancelButton = true
searchBar.searchBarStyle = .minimal
return searchBar
}
func updateUIView(_ uiView: UISearchBar, context: Context) {
uiView.text = text
}
func makeCoordinator() -> Coordinator {
Coordinator(text: $text)
}
class Coordinator: NSObject, UISearchBarDelegate {
@Binding var text: String
init(text: Binding<String>) {
_text = text
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
text = searchText
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
text = ""
searchBar.resignFirstResponder()
}
}
}
In the SearchBarWrapper
view, we're embedding the SearchBar
view and a button for canceling the search. The SearchBar
view is a UIViewRepresentable
that wraps a UISearchBar
. We're using a coordinator here to update the text binding whenever the user types or cancels the search.
TabView
element, which wraps a collection of tab items.TabView {
// your tab views go here
}
You can customize the appearance of the tab bar by calling the UITabBar.appearance()
method and setting its properties.
onSelect
callback of the Tab
element to perform an action.Tab {
// your tab view goes here
}
.onSelect {
// handle tap
}
By following the steps above and customizing the appearance of the navigation bar and tab bar, you can achieve a similar look and feel to the Apple TV app in your SwiftUI app for iOS 16.
