Until now the default displayMode
for UINavigationItem
was small title and it changed in SwiftUI to be large by default.
Is it possible to use the old small title style?
To customize a navigation bar title view in SwiftUI, we simply set ToolbarItem of placement type . principal to a new toolbar modifier. Text("Hello, SwiftUI!") <1> Because this is a customize of navigation bar title, a view needs to be embedded inside a NavigationView .
The navigation bar is on by default within a NavigationView. It can be hidden using navigationBarHidden(_:) . Note that the navigation bar can be unhidden by child views. navigationBarHidden(_:) is a preference value, and uses the value proposed by the deepest view in the hierarchy as its active value.
To change a navigation bar color in SwiftUI, you apply toolbarBackground modifier to the content view of NavigationStack . NavigationView is deprecated in iOS 16. toolbarBackground accepts two parameters. ShapeStyle : The style to display as the background of the bar.
NavigationView is one of the most important components of a SwiftUI app, allowing us to push and pop screens with ease, presenting information in a clear, hierarchical way for users.
It is possible by passing displayMode: .inline
attribute to navigationBarTitle()
NavigationView { List { Text("Text") }.navigationBarTitle(Text("Title"), displayMode: .inline) }
Starting from iOS 14 the navigationBarTitle
modifier is deprecated.
Instead we should "Use navigationTitle(_:) with navigationBarTitleDisplayMode(_:)"
:
List { Text("Text") } .navigationTitle("Title") .navigationBarTitleDisplayMode(.inline)
