Can you add UIViewRepresentable (UISearchBar) as a navigationBarItem? - SwiftUI - swiftui

I am setting the leading and trailing navigationBarItems like this
.navigationBarItems(leading: SearchBar(text: $searchText), trailing: rightTopBarItems())
The trailing items show up fine but SearchBar does not appear. Is it possible to add a UIViewRepresentable as a navigationBarItem? I cannot find anything in the documentation.
SearchBar code:
import SwiftUI
struct SearchBar: UIViewRepresentable {
#Binding var text: String
class Coordinator: NSObject, UISearchBarDelegate {
#Binding var text: String
init(text: Binding<String>) {
_text = text
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
text = searchText
}
}
func makeCoordinator() -> SearchBar.Coordinator {
return Coordinator(text: $text)
}
func makeUIView(context: UIViewRepresentableContext<SearchBar>) -> UISearchBar {
let searchBar = UISearchBar(frame: .zero)
searchBar.delegate = context.coordinator
searchBar.autocapitalizationType = .none
searchBar.searchBarStyle = UISearchBar.Style.minimal
return searchBar
}
func updateUIView(_ uiView: UISearchBar, context: UIViewRepresentableContext<SearchBar>) {
uiView.text = text
}
}

I had the same problem.
So, I gave up adding UIViewRepresentable and decided to useTextField directly.
I hope this serves your purpose.
struct SearchTextField: View {
#State var input: String = ""
#Binding var searchText: String
var body: some View {
HStack {
Image(systemName: "magnifyingglass")
TextField("Search word", text: $input, onCommit: {
self.searchText = self.input
})
}
}
}
final class SearchViewModel: ObservableObject {
#Published var searchText = ""
}
struct ContentView: View {
#ObservedObject var viewModel = SearchViewModel()
var body: some View {
NavigationView {
Text("Hello")
.navigationBarTitle(Text(""), displayMode: .inline)
.navigationBarItems(leading:
HStack {
SearchTextField(searchText: $viewModel.searchText)
}
)
}
}
}

Get PDF-Scanner in fullscreen in a sheet in SwiftUI

I am working on a PDF-Scanner and want to realize it with SwiftUI. I know that I have to work with UIViewRepresentable to get this done.
So the user should open the Camera (to scan the document) in a Sheetview, but the camera doesn't open. If I put it in a Navigationview, it works fine.
My questions are:
Is it possible to open the camera in Sheetviews (fullscreen). Or is it possible put the CameraView in a limited frame in the SheetView to get this done.
Thanks a lot

How to past an image in TextEditor SwiftUI like oneNote/notion?

I want to paste an image in line with text like apps one note or notion do. I read somewhere that it's impossible with TextEditor and I had to use UITextView instead, so I did that but I do not know how to trigger the event PASTE to paste the picture.
Once I do that I will need to figure out how to save the whole shebang in CoreData (the text only as text, the imgs as images). But now I just need help to figure out how to paste an image into a TextEditor or UITextView. Thanks

Clearing Binding text to textfield still shows text in textfield

I have a textField and next to it a button that should clear the text. My problems is though that the TextField View only carries a binder. Hence the actual text in the textfield isn't deleted since Bindings doesn't reload views.
I tried to narrow it down as much as possible in an example:
struct ContentView: View {
#State var presentedView = false
#State var text: String = ""
var body: some View {
Button("Hello, world!") { presentedView = true }
.padding()
.sheet(isPresented: $presentedView, content: {
SomeView(viewModel: .init(textBinder: $text), text: $text)
})
}
}
struct SomeView: View {
let viewModel: ViewModel
#Binding var text: String
var body: some View {
HStack {
TextFieldTyped(text: $text)
Spacer()
Button("erase") {
$text.wrappedValue = ""
}
}
}
struct ViewModel {
let textBinder: Binding<String>
}
}
struct TextFieldTyped: UIViewRepresentable {
#Binding var text: String
func makeUIView(context: Context) -> UITextField {
let textField = UITextField(frame: .zero)
textField.delegate = context.coordinator
return textField
}
func updateUIView(_ uiView: UITextField, context: Context) {
uiView.becomeFirstResponder()
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, UITextFieldDelegate {
var parent: TextFieldTyped
init(_ textField: TextFieldTyped) {
self.parent = textField
}
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
if (textField.text?.count ?? 0) == 1, string.isEmpty {
parent.text = string
} else if string.isEmpty, !(textField.text ?? "").isEmpty {
parent.text = String(textField.text?.dropLast() ?? "")
} else {
parent.text = (textField.text ?? "").isEmpty ? string : (textField.text ?? "") + string
}
return true
}
}
}
try the following code without the useless ViewModel, and an update of text in updateUIView:
struct ContentView: View {
#State var presentedView = false
#State var text: String = ""
var body: some View {
Button("Hello, world!") { presentedView = true }
.padding()
.sheet(isPresented: $presentedView, content: {
SomeView(text: $text)
})
}
}
struct SomeView: View {
#Binding var text: String
var body: some View {
HStack {
TextFieldTyped(text: $text)
Spacer()
Button("erase") {
text = "" // <--- here
}
}
}
}
struct TextFieldTyped: UIViewRepresentable {
#Binding var text: String
func makeUIView(context: Context) -> UITextField {
let textField = UITextField(frame: .zero)
textField.delegate = context.coordinator
return textField
}
func updateUIView(_ uiView: UITextField, context: Context) {
uiView.becomeFirstResponder()
uiView.text = text // <--- here
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, UITextFieldDelegate {
var parent: TextFieldTyped
init(_ textField: TextFieldTyped) {
self.parent = textField
}
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
if (textField.text?.count ?? 0) == 1, string.isEmpty {
parent.text = string
} else if string.isEmpty, !(textField.text ?? "").isEmpty {
parent.text = String(textField.text?.dropLast() ?? "")
} else {
parent.text = (textField.text ?? "").isEmpty ? string : (textField.text ?? "") + string
}
return true
}
}
}
The other answer is perfectly fine but it is also good idea to pull related vars out into their own struct, as recommended in Data Essentials in SwiftUI (WWDC20) at 4:00. Here is how I think it would be achieved in your case:
struct SomeViewConfig {
var presented = false
var text: String = ""
mutating func present() {
presented = true
text = ""
}
}
struct ContentView2: View {
#State var someViewConfig = SomeViewConfig()
var body: some View {
Button("Hello, world!") { someViewConfig.present() }
.padding()
.sheet(isPresented: $someViewConfig.presented) {
SomeView(config: $someViewConfig)
}
}
}
struct SomeView: View {
#Binding var config: SomeViewConfig
var body: some View {
HStack {
TextFieldTyped(text: $config.text)
Spacer()
Button("erase") {
config.text = ""
}
}
}
}

SwiftUI Searchbar pushed off screen by keyboard

I have implemented a searchbar that filters a list. However when the keyboard appears it pushes the searchbar right off the screen. I have tried using .ignoresSafeArea(.keyboard) however it will not work (I have tried placing it in many different spots). I would like to make it so the view/list does not move at all when the keyboard appears.
I am displaying this view below after pressing a button
//MARK: - ActivitySelectorView
ActivitySelectorView(showActivitySelector: $showActivitySelector, activityToSave: activityToSave, allActivities: activities, categoryNames: categoryNames)
.environmentObject(activityToSave)
.frame(width: screen.width, height: screen.height)
.offset(x: showActivitySelector ? 0 : screen.width)
.offset(y: screen.minY)
.offset(x: viewState.width)
.animation(.easeInOut)
And inside ActivitySelectorView I have a title bar and the filtered list which includes a searchbar and list
var body: some View {
ZStack {
//backgroundColor
Color("\(activityToSave.category)Color")
VStack {
TitleBar(showingAlert: $showingAlert, showActivitySelector: $showActivitySelector, categoryName: categoryNames[(Int(String(activityToSave.category.last!)) ?? 1) - 1])
//MARK: - LIST
FilteredList(filter: activityToSave.category, passedActivityBinding: $activityToSave.activityName, showActivitySelector: $showActivitySelector)
.colorMultiply(Color("\(activityToSave.category)Color"))
}
}
}
Here we have FilteredList:
var body: some View {
List {
SearchBar(text: $searchText)
ForEach(fetchRequest.wrappedValue.filter({ searchText.isEmpty ? true : $0.name.contains(searchText) }), id: \.self) { activity in
Text(activity.name.capitalized)
.onTapGesture {
self.showActivitySelector = false
self.selectedActivity = activity.name.capitalized
}
}.onDelete(perform: deleteActivity)
}
.resignKeyboardOnDragGesture()
}
And last the code for the searchBar
struct SearchBar: UIViewRepresentable {
#Binding var text: String
class Coordinator: NSObject, UISearchBarDelegate {
#Binding var text: String
init(text: Binding<String>) {
_text = text
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
text = searchText
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
UIApplication.shared.endEditing()
}
}
func makeCoordinator() -> Coordinator {
return Coordinator(text: $text)
}
func makeUIView(context: Context) -> UISearchBar {
let searchBar = UISearchBar(frame: .zero)
searchBar.delegate = context.coordinator
searchBar.returnKeyType = .done
searchBar.enablesReturnKeyAutomatically = false
return searchBar
}
func updateUIView(_ uiView: UISearchBar, context: Context) {
uiView.text = text
}
}

View automatically jumps to Multiline Text Field

My SwiftUI View is kinda acting weird since i added a MultilineTextField. When pressing a item on the List, the view kind jumps back and forth and then it jumps automatically to the last text field in the view as seen in this video. This just happened after i added a MultilineTextField at the end.

When you opening the view, your Custom TextField calls firstResponders. Just remove calling firstResponder on load and your view will start at the beginning.
func updateUIView(_ uiView: UITextView, context: UIViewRepresentableContext<UITextViewWrapper>) {
if uiView.text != self.text {
uiView.text = self.text
}
if uiView.window != nil, !uiView.isFirstResponder {
//uiView.becomeFirstResponder() << Here calling firstResponder
}
UITextViewWrapper.recalculateHeight(view: uiView, result: $calculatedHeight)
}
SwiftUI TextFields do not support firstResponder yet, however with Representable and using UIKit it is possible, like in your solution, Grüezi
