I want to open a new view using a button that is in a navigationBarItems. I put my code. Thanks for your help.
struct ClienteView: View {
var body: some View {
NavigationView {
List(clientes) { cliente in
NavigationLink(destination: DetallesClienteView(objCliente: cliente)){
DetallesCliente(objCliente: cliente)
}
}
.navigationBarTitle(Text("Clientes"), displayMode: .inline)
.navigationBarItems(trailing:
Button(action: {
}) {
Image(systemName: "person.badge.plus")
}
)
}
}
}
You can do this kind of thing:
.navigationBarItems(trailing:
NavigationLink(destination: SecondView(), label: {
Image(systemName: "person.badge.plus")
})
)

I am making an app where the first view the users see is a home screen with buttons that takes them to a second view. One of the second views present the user with a list of items. When the user clicks on one of these items the user comes to a detailed view of the item. When the user comes to the detailed view he is unfortunately presented with two toolbar buttons in the corner as can be seen here:
.
I know that one of the solutions is to only have one navigationview and that solves my problem. But I need to have toolbar items in my listview to be able to add more items, sort the list and have the list searchable which I'm not able to do without navigationView. I Have tried using scrollView and NavigationStack but it comes out blank.
Does anyone have an idea how to work with mulitple views, not getting double up "back buttons" on the toolbar and still have other toolbar items?
View one: (Home Screen):
NavigationView {
ZStack {
VStack {
Text(title)
.font(.custom("Glacial Indifference", size: 34, relativeTo: .headline).weight(.bold))
.multilineTextAlignment(.leading)
.foregroundColor(.white)
.tracking(10)
.padding(8)
.background(
Rectangle()
.fill(.gray)
.frame(width: 1000, height: 150)
.ignoresSafeArea()
.opacity(0.5))
Spacer()
}
VStack {
NavigationLink {
MapView()
} label: {
Buttons(str: "Cheese Map")
}
.padding(.bottom, 200)
}
VStack {
NavigationLink {
TabView()
} label: {
Buttons(str: "Cheese List")
}
.padding(.bottom, 400)
}
Second View (list):
NavigationView {
List {
ForEach(items, id: \.id) { item in
NavigationLink {
ItemView(item: item)
} label: {
ListItem(item: item)
}
}
}
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
showingAddItem = true
} label: {
Image(systemName: "plus")
Text("Add Item")
.font(.footnote)
.italic()
}
}
}
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
Menu("Sort") {
Picker("Filter Options", selection: $selectedSort) {
ForEach(sortOptions, id: \.self) {
value in
Text(value)
.tag(value)
}
}
}
.onChange(of: selectedSort) { _ in
let sortBy = sorts[sortOptions.firstIndex(of: selectedSort)!]
items.sortDescriptors = sortBy.descriptors
}
}
}
.sheet(isPresented: $showingAddItems) {
AddItemsView(items: Items())
}
.navigationTitle("Item List")
.searchable(text: $searchText)
}
}
}
DetailView:
ScrollView {
ZStack {
VStack {
//More code...
Both .toolbar and .searchable find the nearest enclosing NavigationView automatically. You do not need a NavigationView in your list view.
Here's a self-contained demo. It looks like this:
Here's the code:
import SwiftUI
import PlaygroundSupport
struct HomeScreen: View {
var body: some View {
NavigationView {
List {
NavigationLink("Cheese Map") { Text("Map") }
NavigationLink("Cheese List") { ListView() }
}
.navigationTitle("Home Screen")
}
.navigationViewStyle(.stack)
}
}
struct ListView: View {
#State var items = ["Cheddar", "Swiss", "Edam"]
#State var search: String = ""
var filteredItems: [String] {
return items.filter {
search.isEmpty
|| $0.localizedCaseInsensitiveContains(search)
}
}
var body: some View {
List(filteredItems, id: \.self) {
Text($0)
}
.searchable(text: $search)
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
withAnimation {
items.append("Gouda")
}
} label: {
Label("Add Item", systemImage: "plus")
}
.disabled(items.contains("Gouda"))
}
}
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
Menu("Sort") {
Button("Ascending") {
withAnimation {
items.sort()
}
}
Button("Descending") {
withAnimation {
items.sort()
items.reverse()
}
}
}
}
}
.navigationTitle("Cheese List")
}
}
PlaygroundPage.current.setLiveView(HomeScreen())
I have the following in problem.
If I try to give a view a color (Color.red for example)
I get the following output:
I can just add .edgesignoressafearea(.top) and the top also gets red. But when I want to add an clickable item, the user won't be able to click it since there still is this invisible bar on the top of the screen. Does Anyone know what my problem is? The problem is in all the tabable views(Timeline, Favorits, Discover, Account). So It must be in either the first code or in tabview (second code) that I send in this post.
When the user clicks on the app first they get this view sending the user to the signin view or the app itself:
var body: some View {
NavigationView {
VStack {
NavigationLink(destination: tabView().navigationBarHidden(true), isActive: $tabview, label: { EmptyView() })
NavigationLink(destination: loginView().navigationBarHidden(true), isActive: $login, label: { EmptyView() })
if tabview == false && login == false {
Text("loading")
.onAppear(perform: checklogin)
}
}
.navigationBarBackButtonHidden(true)
.navigationBarHidden(true)
}
}
Then the apps sends them to tabview:
var body: some View {
TabView(selection: $selection) {
Timeline()
.tabItem {
Label("timeline", systemImage: "house")
}
.tag(0)
Favorits()
.tabItem {
Label("favorits", systemImage: "heart")
}
.tag(1)
Discover()
.tabItem {
Label("discover", systemImage: "network")
}
.tag(2)
Account()
.tabItem {
Label("account", systemImage: "person")
}
.tag(3)
}
.navigationBarBackButtonHidden(true)
.navigationBarHidden(true)
}
The problem happens on all of this views.
This is the view where I made the screenshot of:
var body: some View {
ZStack {
Color.red
Text("Hello fav!")
}
.navigationBarBackButtonHidden(true)
.navigationBarHidden(true)
}
add .edgesIgnoringSafeArea(.top) and remove your navigation bar if you don't want to be able to get back to your login view anytime.
That's the full code with a login page, now it depends what you want on that login page :
import SwiftUI
struct ContentView: View {
#State var showLoginView: Bool = false
var body: some View {
VStack {
if showLoginView {
MainView()
} else {
Button("Login") {
self.showLoginView = true
}
}
}
}
}
struct MainView: View {
var body: some View {
TabView {
TimeLine()
.tabItem {
Label("timeline", systemImage: "house")
}
Favorits()
.tabItem {
Label("favorits", systemImage: "heart")
}
Discover()
.tabItem {
Label("discover", systemImage: "network")
}
Account()
.tabItem {
Label("account", systemImage: "person")
}
}
}
}
struct TimeLine: View {
var body: some View {
Color.blue
.edgesIgnoringSafeArea(.top)
}
}
struct Favorits: View {
var body: some View {
ZStack {
Color.red
.edgesIgnoringSafeArea(.top)
Text("Hello fav!")
}
}
}
struct Discover: View {
var body: some View {
Color.yellow
.edgesIgnoringSafeArea(.top)
}
}
struct Account: View {
var body: some View {
Color.purple
.edgesIgnoringSafeArea(.top)
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
You need to set the navigation Title to "" because your View is embedded in NavigationView
Create a ViewModifier like this and apply it to your VStack
struct HiddenNavBarModifier: ViewModifier {
func body(content: Content) -> some View {
content
.navigationBarTitle("", displayMode: .inline)
.navigationBarHidden(true)
}
}
ToolbarItem(placement: .bottomBar) {
NavigationLink(
destination: NoteView(note: Note())
) {
Image(systemName: "square.and.pencil")
}
}
This code is not working as expected: no action is being performed when I tap on the image.
Any idea why or way around?
A possible workaround is to move the NavigationLink outside the toolbar and activate with the isActive parameter:
struct ContentView: View {
#State var linkActive = false
var body: some View {
NavigationView {
Text("Test")
.background(
NavigationLink(destination: Text("Destination"), isActive: $linkActive) {}
)
.toolbar {
ToolbarItem(placement: .bottomBar) {
Button(action: {
linkActive = true
}) {
Image(systemName: "square.and.pencil")
}
}
}
}
}
}
I have a NavigationView with a card of Info and then a list, I would like to tap the info and go to another view, or you could tap an item of a list and see more info about an item.
So, if I give 'onTapGesture' modifier to the card view it does print"onTap pressed', but I can't figure our how to make it start another view
var body: some View {
NavigationView {
VStack {
TopResultsCard(games: self.games)
.padding(.top, 10)
.onTapGesture({
print("onTap tapped")
})
ResultsListItem(games: self.games)
}.navigationBarTitle("", displayMode: .inline)
.navigationBarItems(trailing:
Button(action: {
self.showNewResult.toggle()
}) {
Image(systemName: "plus.circle")
Text("Add result")
}
.sheet(isPresented: $showNewResult) {AddResultView(games: self.games)}
.font(.caption))
}
}
Here is possible approach. Use your destination view instead of demo Text("Next view here") below.
#State private var isActive = false
var body: some View {
NavigationView {
VStack {
TopResultsCard(games: self.games)
.padding(.top, 10)
.onTapGesture { self.isActive.toggle() }
.background(NavigationLink(destination:
Text("Next view here"), isActive: $isActive) { EmptyView() })
ResultsListItem(games: self.games)
}.navigationBarTitle("", displayMode: .inline)
.navigationBarItems(trailing:
Button(action: {
self.showNewResult.toggle()
}) {
Image(systemName: "plus.circle")
Text("Add result")
}
.sheet(isPresented: $showNewResult) {AddResultView(games: self.games)}
.font(.caption))
}
}
I have a view that has navigation bar items and I embed that view in a TabView. But when doing that, the bar items no longer appear. If I call the view outside of a TabView everything works as expected.
Below a small sample project to illustrate my issue, note that the TabView is not called on the initial ContentView but later down:
import SwiftUI
struct ContentView: View {
var body: some View {
NavigationView{
NavigationLink(destination: WarehouseOrderTabView()){
Text("Click me")
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
struct WarehouseOrderTabView: View {
var body: some View {
TabView{
TabView1().navigationBarTitle("Dashboard")
.tabItem {
Image(systemName: "gauge")
Text("Dashboard")
}
TabView2().navigationBarTitle("Orders")
.tabItem {
Image(systemName: "list.dash")
Text("Orders")
}
}
}
}
struct TabView1: View {
var body: some View {
Text("TabView 1")
//I would expect to see those bar items when displaying tab 1
.navigationBarItems(trailing: (
HStack{
Button(action: {
}, label: {
Image(systemName: "arrow.clockwise")
.font(.title)
})
.padding(.init(top: 0, leading: 0, bottom: 0, trailing: 20))
Button(action: {
}, label: {
Image(systemName: "slider.horizontal.3")
.font(.title)
})
}
))
}
}
struct TabView2: View {
var body: some View {
Text("TabView 2")
}
}
What am I missing here?
A NavigationView can be embedded in a TabView and not vice-versa.
TabView contains different tabItem() (at most 5) that can contain your views.
This is how you can use it.
TabView1.swift
struct TabView1: View {
var body: some View {
NavigationView {
Text("TabView 1")
.navigationBarTitle("Dashboard")
.navigationBarItems(trailing:
HStack {
Button(action: {
// more code here
}) {
Image(systemName: "arrow.clockwise")
.font(.title)
}
Button(action: {
// more code here
}) {
Image(systemName: "slider.horizontal.3")
.font(.title)
}
}
)
}
}
}
TabView2.swift
struct TabView2: View {
var body: some View {
NavigationView {
NavigationLink(destination: YourNewView()) {
Text("TabView 1")
}
.navigationBarTitle("Orders")
}
}
}
ContentView.Swift
import SwiftUI
struct ContentView: View {
var body: some View {
TabView {
TabView1()
.tabItem {
Image(systemName: "gauge")
Text("Dashboard")
}
TabView2()
.tabItem {
Image(systemName: "list.dash")
Text("Orders")
}
}
}
}
Hope it helps :)
