I have a TabBarView
in the root view. In one of the parent views that's nested within the root view, I'd like the tab bar to hide when navigating from that parent view to the child view. Is there any func or command to handle that?
Something like this:
ContentView (with TabBarView) - > ExploreView (Called in TabBarView ) -> MessagesView (Child of ExploreVIew - Hide Tab bar)
My code can be seen below.
TabView{
NavigationView{
GeometryReader { geometry in
ExploreView()
.navigationBarTitle(Text(""), displayMode: .inline)
.navigationBarItems(leading: Button(action: {
}, label: {
HStack{
Image("cityOption")
Text("BER")
Image("arrowCities")
}.foregroundColor(Color("blackAndWhite"))
.font(.system(size: 12, weight: .semibold))
}),trailing:
HStack{
Image("closttop")
.renderingMode(.template)
.padding(.trailing, 125)
NavigationLink(destination: MessagesView()
.navigationBarTitle(Text("Messages"), displayMode: .inline)
.navigationBarItems(trailing: Image("writemessage"))
.foregroundColor(Color("blackAndWhite"))
){
Image("messages")
}
}.foregroundColor(Color("blackAndWhite"))
)
}
}
.tabItem{
HStack{
Image("clostNav").renderingMode(.template)
Text("Explore")
.font(.system(size: 16, weight: .semibold))
}.foregroundColor(Color("blackAndWhite"))
}
SearchView().tabItem{
Image("search").renderingMode(.template)
Text("Search")
}
PostView().tabItem{
HStack{
Image("post").renderingMode(.template)
.resizable().frame(width: 35, height: 35)
}
}
OrdersView().tabItem{
Image("orders").renderingMode(.template)
Text("Orders")
}
ProfileView().tabItem{
Image("profile").renderingMode(.template)
Text("Profile")
}
}
Appreciate any help! Thanks!

A bit late here, on iOS 16 you could use ContentView().toolbar( .hidden, for: .tabBar)
So in your case, it would be like as below,
struct ExploreView: View {
var body: some View {
some_view {
}
.toolbar(.hidden, for: .tabBar)
}
}

import UIKit
import SwiftUI
struct ViewControllerHolder {
weak var value: UIViewController?
}
struct ViewControllerKey: EnvironmentKey {
static var defaultValue: ViewControllerHolder { return
ViewControllerHolder(value:
UIApplication.shared.windows.first?.rootViewController ) }
}
extension EnvironmentValues {
var viewController: ViewControllerHolder {
get { return self[ViewControllerKey.self] }
set { self[ViewControllerKey.self] = newValue }
}
}
extension UIViewController {
func present<Content: View>(style: UIModalPresentationStyle =
.automatic, @ViewBuilder builder: () -> Content) {
// Must instantiate HostingController with some sort of view...
let toPresent = UIHostingController(rootView:
AnyView(EmptyView()))
toPresent.modalPresentationStyle = style
// ... but then we can reset rootView to include the environment
toPresent.rootView = AnyView(
builder()
.environment(\.viewController, ViewControllerHolder(value:
toPresent))
)
self.present(toPresent, animated: true, completion: nil)
}
}
@Environment(\.viewController) private var viewControllerHolder:
ViewControllerHolder
private var viewController: UIViewController? {
self.viewControllerHolder.value
}
var body: some View {
NavigationView {
ZStack {
Text("Navigate")
}.onTapGesture {
self.viewController?.present(style: .fullScreen) {
EditUserView()
}
}
}
}

in a normal iphone environment the tabbar vanishes from itself if you are navigating....or are u running in another environment?
check this:
struct ContentView: View {
@State var hideTabbar = false
@State var navigate = false
var body: some View {
NavigationView {
TabView {
VStack {
NavigationLink(destination: Text("without tab")){
Text("aha")
}
.tabItem {
Text("b")
}
}.tag(0)
Text("Second View")
.tabItem {
GeometryReader { geometry in
Image(systemName: "2.circle")
// Text("Second")
Text("\(geometry.size.height) - \(geometry.size.width)")
}
}.tag(1)
}
}
}//.isHidden(self.hideTabbar)
}
