Creating custom navigation bar appearances in SwiftUI can significantly enhance the visual appeal and user experience of your application. SwiftUI allows you to easily modify various aspects of the navigation bar, including its background color, title font, and transparency. This example demonstrates how to create a custom navigation bar with a unique appearance.
import SwiftUI
struct CustomNavigationBarView: View {
var body: some View {
NavigationView {
VStack {
Text("Hello, SwiftUI!")
.font(.largeTitle)
.padding()
NavigationLink(destination: DetailView()) {
Text("Go to Detail View")
.font(.title)
.padding()
.background(Color.blue)
.foregroundColor(.white)
.cornerRadius(8)
}
}
.navigationTitle("Custom Nav Bar")
.navigationBarTitleDisplayMode(.inline)
.toolbar {
ToolbarItem(placement: .navigationBar) {
HStack {
Button(action: {
// Custom Action
}) {
Image(systemName: "bell")
.foregroundColor(.white)
}
}
}
}
.background(Color.pink.edgesIgnoringSafeArea(.top))
}
}
}
struct DetailView: View {
var body: some View {
Text("Detail View")
.font(.largeTitle)
.navigationTitle("Detail")
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
CustomNavigationBarView()
}
}
