Reloading Previous View from Navbar - ios

I have been following a tutorial on creating a weather app. I am trying to take it further. When on the weather view the user can click a plus button which takes them to a location view. Here the user will be able to update the location then when going back the weather will reload. But i am really struggling to get the weather to reload when pressing the back button.
Below is my code for the WeatherView & LocationView
Thank you
struct WeatherView: View {
#State private var isShowing = false
#State var width = UIScreen.main.bounds.width - 60
#State var x = -UIScreen.main.bounds.width + 60
#ObservedObject var input = CityId()
let heptics = UIImpactFeedbackGenerator(style: .medium)
#ObservedObject var weatherViewModel = WeatherViewModel()
var body: some View {
NavigationView{
ZStack {
BackgroundView()
VStack {
if weatherViewModel.stateView == .loading {
ActivityIndicatorView(isAnimating: true).configure {
$0.color = .white
}
}
if weatherViewModel.stateView == .success {
LocationAndTemperatureHeaderView(data: weatherViewModel.currentWeather)
Spacer()
ScrollView(.vertical, showsIndicators: false) {
VStack {
DailyWeatherCellView(data: weatherViewModel.todayWeather)
Rectangle().frame(height: CGFloat(1))
HourlyWeatherView(data: weatherViewModel.hourlyWeathers)
Rectangle().frame(height: CGFloat(1))
DailyWeatherView(data: weatherViewModel.dailyWeathers)
Rectangle().frame(height: CGFloat(1))
Text(weatherViewModel.currentDescription)
.frame(maxWidth: .infinity, alignment: .leading)
.padding(
.init(arrayLiteral:.leading,.trailing),
24
)
Rectangle().frame(height: CGFloat(1))
DetailsCurrentWeatherView(data: weatherViewModel.currentWeather)
Rectangle().frame(height: CGFloat(1))
}
}
Spacer()
}
if weatherViewModel.stateView == .failed {
Button(action: {
self.weatherViewModel.retry()
}) {
Text("Failed get data, retry?")
.foregroundColor(.white)
}
}
}
}.colorScheme(.dark)
.listStyle(InsetGroupedListStyle())
.background(
NavigationLink(destination: LocationView(input: input, weatherViewModel: weatherViewModel), isActive: $isShowing) {
EmptyView()
}
) // End of Background
.navigationBarTitle((input.score), displayMode: .inline)
.toolbar {
ToolbarItem(placement: .navigationBarTrailing){
Button(action: {
isShowing = true
heptics.impactOccurred()
}) {
Image(systemName: "plus")
}
} // End of ToolbarItem
} // End of Toolbar
} // End of Nav View
} // End of body
} // End of View
struct LocationView: View {
#ObservedObject var input: CityId
#ObservedObject var weatherViewModel: WeatherViewModel
#Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
var body: some View {
Button(action: {
input.score = "2643743"
weatherViewModel.stateView = .loading
self.presentationMode.wrappedValue.dismiss()
}) {
Image(systemName: "plus")
}
.navigationBarBackButtonHidden(true)
}
}

You may consider adding .onAppear modifier to your first view then you can update the data.

How can I make a side bar in SwiftUI in navigationstack

I am trying to make a sidebar in swiftUI that is triggered in and out from the side with a button
I have been able to make it pop in and out from the bottom using a side modifier like this
struct sideBarExample: View {
#State var showSideBar = false
var mainView: some View{
Rectangle()
.foregroundColor(.blue)
.overlay(Text("Main View"))
}
var sideBar: some View{
Rectangle()
.foregroundColor(.green)
.overlay(Text("side bar"))
}
var body: some View {
NavigationStack{
mainView
.sheet(isPresented: $showSideBar, content: {
sideBar
})
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
showSideBar.toggle()
} label: {
Image(systemName: "sidebar.left")
}
}
}
}
}
}
But ideally it should be from the side
For iPhone you have to build your own sidebar, just overlay it in a ZStack and animate in with .transition.
struct ContentView: View {
#State private var showSideBar = false
var mainView: some View{
Rectangle()
.foregroundColor(.gray)
.overlay(Text("Main View"))
}
var sideBar: some View{
Rectangle()
.foregroundColor(.green)
.overlay(Text("side bar"))
.frame(width: 200)
}
var body: some View {
NavigationStack{
ZStack(alignment: .leading) {
mainView
if showSideBar {
sideBar
.transition(.move(edge: .leading))
}
}
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
withAnimation {
showSideBar.toggle()
}
} label: {
Image(systemName: "sidebar.left")
}
}
}
}
}
}
You can use the offset view modifier to move the sidebar around
Here is an example
struct SideBarExample: View {
#State var showSideBar = false
var mainView: some View{
Rectangle()
.foregroundColor(.blue)
.overlay(Text("Main View"))
}
var sideBar: some View{
HStack{
Rectangle()
.foregroundColor(.green)
.overlay(Text("side bar"))
.frame(width:250)
Spacer()
}
}
var body: some View {
NavigationStack{
ZStack{
mainView
sideBar
.offset(CGSize(width: showSideBar ? 0:-250, height: 0))
}
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
withAnimation {
showSideBar.toggle()
}
} label: {
Image(systemName: "sidebar.left")
}
}
}
}
}
}
Here is what that looks like

How to add button next to search bar when selected in SwiftUI (or UIKit if it's not possible in SwiftUI)?

How can I add a button next to the searchbar when it is currently selected in SwiftUI? An example of what I am talking about is below:
This is the code I have currently:
struct ContentView: View {
#State private var searchText = ""
var body: some View {
NavigationView {
VStack {
Text("Hello")
}
.searchable(text: $searchText)
.navigationTitle("Hello")
}
}
}
If this is not possible to do in SwiftUI, is there a way I can accomplish this by utilizing UIKit in my SwiftUI view?
You can achieve this very easily with #FocusState. here is complete code, you can change it according to your requirements.
struct CustomSearchBar: View {
#Binding var text: String
#State private var isEditing = false
#FocusState private var isSearchFocused: Bool
var body: some View {
HStack {
Image(systemName: "magnifyingglass")
.foregroundColor(.white)
.padding([.leading])
TextField("Search ...", text: $text)
.padding([.trailing,. top, .bottom],7)
.foregroundColor(.white)
.opacity(isEditing ? 1 : 0.7)
.focused($isSearchFocused)
if isSearchFocused {
Button(action: {
// do you option event
}) {
Image("option")
.resizable()
.frame(width: 25, height: 25)
}
.padding(.trailing, 10)
.transition(.move(edge: .trailing))
}
Button(action: {
// do you cancle event
isSearchFocused = false
}) {
Text("Cancel")
}
.padding(.trailing, 10)
.transition(.move(edge: .trailing))
}
.padding()
.background(.gray.opacity(0.3))
.onChange(of: isSearchFocused) { newValue in
text = ""
}
}
}

SwiftUI App not displaying sheet on button tap

I am creating a SwiftUI app and wanted to add a settings screen that would be displayed as a modal sheet when tapping on a gear icon. For some reason when tapping on the gear when the app is running on a device or the simulator, the sheet does not appear. However, it does appear on the Xcode Preview when I run it.
I have included the entire ContentView code below and highlighted the part with the button that is supposed to display the sheet. SettingsPage() is just the normal SwiftUI template that says Hello, World.
Thanks.
struct ContentView: View {
#StateObject var locationViewModel = LocationManager()
#State private var showMoreInfo: Bool = false
#State private var showingTopSpeed: Bool = false
#State var showingSettingsScreen: Bool = false
private var currentSpeed: String = "Your current speed is:"
private var topSpeed: String = " Your top speed is:"
var body: some View {
VStack {
HStack(alignment: .lastTextBaseline) {
GPSStrengthView(horizontalAccuracy: locationViewModel.userHorizontalAccuracy)
Spacer()
Button(action: {
withAnimation {
showingTopSpeed.toggle()
print("Toggling showing top speed")
}
}) {
Image(systemName: "speedometer")
.foregroundColor(showingTopSpeed ? .primary : .accentColor)
}
Button(action: {
withAnimation {
showMoreInfo.toggle()
}
}) {
Image(systemName: "filemenu.and.selection")
.renderingMode(.original)
}
//BUTTON IN QUESTION ####################################
Button(action: {
showingSettingsScreen = true
}) {
Image(systemName: "gear")
} .sheet(isPresented: $showingSettingsScreen, content: {
SettingsPage()
})
//############################################
}
.padding(.leading)
.padding(.trailing)
Spacer()
Text(showingTopSpeed ? currentSpeed : topSpeed)
SpeedView(speed: showingTopSpeed ? locationViewModel.userSpeed : locationViewModel.userTopSpeed)
if showMoreInfo {
Text(String(format: "With an accuracy of: +/- %.2f", locationViewModel.userSpeedAccuracy * 2.236936))
.animation(.easeInOut)
}
Spacer()
HStack {
Spacer()
CompassView()
.scaleEffect(scaleVar)
.frame(width: frameDimensions, height: frameDimensions)
}
.padding()
}
}
Try moving your .sheet() to the outermost VStack instead of applying it directly to the Button
struct ContentView: View {
#StateObject var locationViewModel = LocationManager()
#State private var showMoreInfo: Bool = false
#State private var showingTopSpeed: Bool = false
#State var showingSettingsScreen: Bool = false
private var currentSpeed: String = "Your current speed is:"
private var topSpeed: String = " Your top speed is:"
var body: some View {
VStack {
HStack(alignment: .lastTextBaseline) {
GPSStrengthView(horizontalAccuracy: locationViewModel.userHorizontalAccuracy)
Spacer()
Button(action: {
withAnimation {
showingTopSpeed.toggle()
print("Toggling showing top speed")
}
}) {
Image(systemName: "speedometer")
.foregroundColor(showingTopSpeed ? .primary : .accentColor)
}
Button(action: {
withAnimation {
showMoreInfo.toggle()
}
}) {
Image(systemName: "filemenu.and.selection")
.renderingMode(.original)
}
//BUTTON IN QUESTION ####################################
Button(action: {
showingSettingsScreen = true
}) {
Image(systemName: "gear")
}
//############################################
}
.padding(.leading)
.padding(.trailing)
Spacer()
Text(showingTopSpeed ? currentSpeed : topSpeed)
SpeedView(speed: showingTopSpeed ? locationViewModel.userSpeed : locationViewModel.userTopSpeed)
if showMoreInfo {
Text(String(format: "With an accuracy of: +/- %.2f", locationViewModel.userSpeedAccuracy * 2.236936))
.animation(.easeInOut)
}
Spacer()
HStack {
Spacer()
CompassView()
.scaleEffect(scaleVar)
.frame(width: frameDimensions, height: frameDimensions)
}
.padding()
}
.sheet(isPresented: $showingSettingsScreen, content: {
SettingsPage()
})
}

Presenting a sheet pops views from NavigationView

I have a view A that contains a NavigationView. A pushes View B by activating a NavigationLink. B pushes View C by activating a NavigationLink. C pushes View D by tapping a NavigationLink. D then presents a View as a sheet. If i dismiss the sheet the current top view is B. For some reason presenting the sheet pops 2 screens.
Can someone explain this behaviour and how i can fix it?
I'm guessing somehow the navigation link in view B (that pushed view C) get deActivated but I cant figure out why
From what i tested it seems when the sheet gets presented ViewB gets reinitialized which will reinit my vm and so deactivate the link. How to i stop the view from being reinitialized?

}
}
}
Although it is not documented, I realised that presenting a .sheet() while the view itself is set to a "no detail view" via .isDetailLink(false) causes this issue.
I can see why, as if the view is not a detail view it cannot present a sheet, hence the sheet is actually presented by the first detail view and that is why it goes back to that view right after the sheet is presented.
Try removing .isDetailLink(false) and finding a different workaround if you really need it to be not a detail link.

NavigationView and NavigationLink on button click in SwiftUI?

I am trying to push from login view to detail view but not able to make it.even navigation bar is not showing in login view. How to push on button click in SwiftUI? How to use NavigationLink on button click?
var body: some View {
NavigationView {
VStack(alignment: .leading) {
Text("Let's get you signed in.")
.bold()
.font(.system(size: 40))
.multilineTextAlignment(.leading)
.frame(width: 300, height: 100, alignment: .topLeading)
.padding(Edge.Set.bottom, 50)
Text("Email address:")
.font(.headline)
TextField("Email", text: $email)
.frame(height:44)
.accentColor(Color.white)
.background(Color(UIColor.darkGray))
.cornerRadius(4.0)
Text("Password:")
.font(.headline)
SecureField("Password", text: $password)
.frame(height:44)
.accentColor(Color.white)
.background(Color(UIColor.darkGray))
.cornerRadius(4.0)
Button(action: {
print("login tapped")
}) {
HStack {
Spacer()
Text("Login").foregroundColor(Color.white).bold()
Spacer()
}
}
.accentColor(Color.black)
.padding()
.background(Color(UIColor.darkGray))
.cornerRadius(4.0)
.padding(Edge.Set.vertical, 20)
}
.padding(.horizontal,30)
}
.navigationBarTitle(Text("Login"))
}
To fix your issue you need to bind and manage tag with NavigationLink, So create one state inside you view as follow, just add above body.
#State var selection: Int? = nil
Then update your button code as follow to add NavigationLink
NavigationLink(destination: Text("Test"), tag: 1, selection: $selection) {
Button(action: {
print("login tapped")
self.selection = 1
}) {
HStack {
Spacer()
Text("Login").foregroundColor(Color.white).bold()
Spacer()
}
}
.accentColor(Color.black)
.padding()
.background(Color(UIColor.darkGray))
.cornerRadius(4.0)
.padding(Edge.Set.vertical, 20)
}
Meaning is, when selection and NavigationLink tag value will match then navigation will be occurs.
I hope this will help you.
iOS 16+
Note: Below is a simplified example of how to present a new view. For a more advanced generic example please see this answer.
In iOS 16 we can access the NavigationStack and NavigationPath.
Usage #1
A new view is activated by a simple NavigationLink:
struct ContentView: View {
var body: some View {
NavigationStack {
NavigationLink(value: "NewView") {
Text("Show NewView")
}
.navigationDestination(for: String.self) { view in
if view == "NewView" {
Text("This is NewView")
}
}
}
}
}
Usage #2
A new view is activated by a standard Button:
struct ContentView: View {
#State private var path = NavigationPath()
var body: some View {
NavigationStack(path: $path) {
Button {
path.append("NewView")
} label: {
Text("Show NewView")
}
.navigationDestination(for: String.self) { view in
if view == "NewView" {
Text("This is NewView")
}
}
}
}
}
Usage #3
A new view is activated programmatically:
struct ContentView: View {
#State private var path = NavigationPath()
var body: some View {
NavigationStack(path: $path) {
Text("Content View")
.navigationDestination(for: String.self) { view in
if view == "NewView" {
Text("This is NewView")
}
}
}
.onAppear {
path.append("NewView")
}
}
}
iOS 13+
The accepted answer uses NavigationLink(destination:tag:selection:) which is correct.
However, for a simple view with just one NavigationLink you can use a simpler variant: NavigationLink(destination:isActive:)
Usage #1
NavigationLink is activated by a standard Button:
struct ContentView: View {
#State var isLinkActive = false
var body: some View {
NavigationView {
VStack(alignment: .leading) {
...
NavigationLink(destination: Text("OtherView"), isActive: $isLinkActive) {
Button(action: {
self.isLinkActive = true
}) {
Text("Login")
}
}
}
.navigationBarTitle(Text("Login"))
}
}
}
Usage #2
NavigationLink is hidden and activated by a standard Button:
struct ContentView: View {
#State var isLinkActive = false
var body: some View {
NavigationView {
VStack(alignment: .leading) {
...
Button(action: {
self.isLinkActive = true
}) {
Text("Login")
}
}
.navigationBarTitle(Text("Login"))
.background(
NavigationLink(destination: Text("OtherView"), isActive: $isLinkActive) {
EmptyView()
}
.hidden()
)
}
}
}
Usage #3
NavigationLink is hidden and activated programmatically:
struct ContentView: View {
#State var isLinkActive = false
var body: some View {
NavigationView {
VStack(alignment: .leading) {
...
}
.navigationBarTitle(Text("Login"))
.background(
NavigationLink(destination: Text("OtherView"), isActive: $isLinkActive) {
EmptyView()
}
.hidden()
)
}
.onAppear {
self.isLinkActive = true
}
}
}
Here is a GitHub repository with different SwiftUI extensions that makes navigation easier.
Another approach:
SceneDelegate
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: BaseView().environmentObject(ViewRouter()))
self.window = window
window.makeKeyAndVisible()
}
BaseView
import SwiftUI
struct BaseView : View {
#EnvironmentObject var viewRouter: ViewRouter
var body: some View {
VStack {
if viewRouter.currentPage == "view1" {
FirstView()
} else if viewRouter.currentPage == "view2" {
SecondView()
.transition(.scale)
}
}
}
}
#if DEBUG
struct MotherView_Previews : PreviewProvider {
static var previews: some View {
BaseView().environmentObject(ViewRouter())
}
}
#endif
ViewRouter
import Foundation
import Combine
import SwiftUI
class ViewRouter: ObservableObject {
let objectWillChange = PassthroughSubject<ViewRouter,Never>()
var currentPage: String = "view1" {
didSet {
withAnimation() {
objectWillChange.send(self)
}
}
}
}
FirstView
import SwiftUI
struct FirstView : View {
#EnvironmentObject var viewRouter: ViewRouter
var body: some View {
VStack {
Button(action: {self.viewRouter.currentPage = "view2"}) {
NextButtonContent()
}
}
}
}
#if DEBUG
struct FirstView_Previews : PreviewProvider {
static var previews: some View {
FirstView().environmentObject(ViewRouter())
}
}
#endif
struct NextButtonContent : View {
var body: some View {
return Text("Next")
.foregroundColor(.white)
.frame(width: 200, height: 50)
.background(Color.blue)
.cornerRadius(15)
.padding(.top, 50)
}
}
SecondView
import SwiftUI
struct SecondView : View {
#EnvironmentObject var viewRouter: ViewRouter
var body: some View {
VStack {
Spacer(minLength: 50.0)
Button(action: {self.viewRouter.currentPage = "view1"}) {
BackButtonContent()
}
}
}
}
#if DEBUG
struct SecondView_Previews : PreviewProvider {
static var previews: some View {
SecondView().environmentObject(ViewRouter())
}
}
#endif
struct BackButtonContent : View {
var body: some View {
return Text("Back")
.foregroundColor(.white)
.frame(width: 200, height: 50)
.background(Color.blue)
.cornerRadius(15)
.padding(.top, 50)
}
}
Hope this helps!
Simplest and most effective solution is :
NavigationLink(destination:ScoresTableView()) {
Text("Scores")
}.navigationBarHidden(true)
.frame(width: 90, height: 45, alignment: .center)
.foregroundColor(.white)
.background(LinearGradient(gradient: Gradient(colors: [Color.red, Color.blue]), startPoint: .leading, endPoint: .trailing))
.cornerRadius(10)
.contentShape(Rectangle())
.padding(EdgeInsets(top: 16, leading: UIScreen.main.bounds.size.width - 110 , bottom: 16, trailing: 20))
ScoresTableView is the destination view.
In my opinion a cleaner way for iOS 16+ is using a state bool to present the view.
struct ButtonNavigationView: View {
#State private var isShowingSecondView : Bool = false
var body: some View {
NavigationStack {
VStack{
Button(action:{isShowingSecondView = true} ){
Text("Show second view")
}
}.navigationDestination(isPresented: $isShowingSecondView) {
Text("SecondView")
}
}
}
}
I think above answers are nice, but simpler way should be:
NavigationLink {
TargetView()
} label: {
Text("Click to go")
}
