Dasturiy navigatsiya

SwiftUI navigatsiya: dasturiy navigatsiya

NavigationPath va tiplashtirilgan manzillar yordamida navigatsiyani kod orqali boshqaring.

Path’ni boshqarish

NavigationPath navigatsiya yo‘lini (path) boshqaradi.

import SwiftUI

struct NumberDetail: View { let n: Int; var body: some View { Text("Number: \(n)") } }

struct ProgrammaticPathDemo: View {
  @State private var path: [Int] = []
  var body: some View {
    NavigationStack(path: $path) {
      VStack(spacing: 12) {
        Button("Go to 42") { path.append(42) }
        Button("Back") { if !path.isEmpty { _ = path.removeLast() } }
      }
      .navigationDestination(for: Int.self) { n in NumberDetail(n: n) }
      .navigationTitle("Programmatic")
    }
  }
}

import SwiftUI

struct ContentView: View {
  var body: some View { ProgrammaticPathDemo() }
}

import SwiftUI

@main
struct MyApp: App {
  var body: some Scene { WindowGroup { ContentView() } }
}

Yuqoridagi misolda navigatsiya yo‘lini boshqarish uchun NavigationPath ishlatilgan.

Qayta o‘rnatish va bir nechta push

Yo‘lni qayta o‘rnating (reset) va bir nechta manzilni push qiling.

import SwiftUI

struct ResetMultiPushDemo: View {
  @State private var path: [Int] = []
  var body: some View {
    NavigationStack(path: $path) {
      VStack(spacing: 12) {
        Button("Reset to root") { path.removeAll() }
        Button("Go to 1 → 2 → 3") { path.append(contentsOf: [1,2,3]) }
      }
      .navigationDestination(for: Int.self) { n in Text("Screen #\(n)") }
      .navigationTitle("Reset & Multi-Push")
    }
  }
}

import SwiftUI

struct ContentView: View {
  var body: some View { ResetMultiPushDemo() }
}

import SwiftUI

@main
struct MyApp: App {
  var body: some Scene { WindowGroup { ContentView() } }
}
