navigationBarTitle(_:displayMode:)

Discussion 議論

Use navigationBarTitle(_:displayMode:) to set the title of the navigation bar for this view and specify a display mode for the title from one of the NavigationBarItem.TitleDisplayMode styles. This modifier only takes effect when this view is inside of and visible within a NavigationView.

In the example below, text for the navigation bar title is provided using a string. 下の例において、ナビゲーションバータイトルに対するテキストは、ある文字列を使って提供されます。 The navigation bar title’s NavigationBarItem.TitleDisplayMode is set to .inline which places the navigation bar title in the bounds of the navigation bar.

struct FlavorView: View {
    let items = ["Chocolate", "Vanilla", "Strawberry", "Mint Chip",
                 "Pistachio"]
    var body: some View {
        NavigationView {
            List(items, id: \.self) {
                Text($0)
            }
            .navigationBarTitle("Today's Flavors", displayMode: .inline)
        }
    }
}

If the titleKey can’t be found, the title uses the text of the key name instead.
