在 SwiftUI 中全屏显示颜色

Question

I'm trying to show red color in full screen.

If I use edgesIgnoringSafeArea(.all) the screen automatically becomes scrolling enabled, which I don't want. Can you please advise me how to show red color on full screen without scrolling and without stretching because i change the color to image.

Any help would be greatly appreciated.

Sample code is given below.

import SwiftUI

struct PageSetup: View {

  @State private var tabSelection = 0

  var body: some View {
    ZStack {
      TabView(selection: $tabSelection) {
        ForEach(0..<5) { index in
          ZStack {
            Color.red
            Text("\(index)")
          }
        }
      }
      .tabViewStyle(PageTabViewStyle())
      .onAppear {
        UIScrollView.appearance().bounces = false
      }
      .tabViewStyle(PageTabViewStyle())
    }
  }
}

If I understood what you wanted correctly, you are using ZStack and Color in wrong place. Your body should be like this code sample.

struct PageSetup: View {

  @State private var tabSelection = 0

  var body: some View {
    ZStack {
      getColorForPage().ignoresSafeArea()
      TabView (selection: $tabSelection) {
        ForEach(0..<5){ index in
          Text("\(index)")
        }
      }
      .tabViewStyle(PageTabViewStyle())
      .onAppear {
        UIScrollView.appearance().bounces = false
      }
    }
  }

  func getColorForPage() -> Color {
    if tabSelection == 0 {
      return Color.red
    } else if tabSelection == 1 {
      return Color.blue
    } else {
      return Color.orange
    }
  }
}
