Is there an equivalent to InputAccessoryView in SwiftUI (or any indication one is coming?)
And if not, how would you emulate the behavior of an InputAccessoryView (i.e. a view pinned to the top of the keyboard)? Desired behavior is something like iMessage, where there is a view pinned to the bottom of the screen that animates up when the keyboard is opened and is positioned directly above the keyboard. For example:
macOS 12.0+,Mac Catalyst 15.0+
ToolbarItemPlacement
has a new property in iOS 15.0+
keyboard
On iOS, keyboard items are above the software keyboard when present, or at the bottom of the screen when a hardware keyboard is attached. On macOS, keyboard items will be placed inside the Touch Bar. https://developer.apple.com
struct LoginForm: View {
@State private var username = ""
@State private var password = ""
var body: some View {
Form {
TextField("Username", text: $username)
SecureField("Password", text: $password)
}
.toolbar(content: {
ToolbarItemGroup(placement: .keyboard, content: {
Text("Left")
Spacer()
Text("Right")
})
})
}
}
struct KeyboardToolbar<ToolbarView: View>: ViewModifier {
private let height: CGFloat
private let toolbarView: ToolbarView
init(height: CGFloat, @ViewBuilder toolbar: () -> ToolbarView) {
self.height = height
self.toolbarView = toolbar()
}
func body(content: Content) -> some View {
ZStack(alignment: .bottom) {
GeometryReader { geometry in
VStack {
content
}
.frame(width: geometry.size.width, height: geometry.size.height - height)
}
toolbarView
.frame(height: self.height)
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
}
}
extension View {
func keyboardToolbar<ToolbarView>(height: CGFloat, view: @escaping () -> ToolbarView) -> some View where ToolbarView: View {
modifier(KeyboardToolbar(height: height, toolbar: view))
}
}
And use .keyboardToolbar
view modifier as you would normally do.
struct ContentView: View {
@State private var username = ""
var body: some View {
NavigationView{
Text("Keyboar toolbar")
.keyboardToolbar(height: 50) {
HStack {
TextField("Username", text: $username)
}
.border(.secondary, width: 1)
.padding()
}
}
}
}
I've solved this problem using 99% pure SwiftUI on iOS 14. In the toolbar you can show any View you like.
That's my implementation:
import SwiftUI
struct ContentView: View {
@State private var showtextFieldToolbar = false
@State private var text = ""
var body: some View {
ZStack {
VStack {
TextField("Write here", text: $text) { isChanged in
if isChanged {
showtextFieldToolbar = true
}
} onCommit: {
showtextFieldToolbar = false
}
.textFieldStyle(RoundedBorderTextFieldStyle())
.padding()
}
VStack {
Spacer()
if showtextFieldToolbar {
HStack {
Spacer()
Button("Close") {
showtextFieldToolbar = false
UIApplication.shared
.sendAction(#selector(UIResponder.resignFirstResponder),
to: nil, from: nil, for: nil)
}
.foregroundColor(Color.black)
.padding(.trailing, 12)
}
.frame(idealWidth: .infinity, maxWidth: .infinity,
idealHeight: 44, maxHeight: 44,
alignment: .center)
.background(Color.gray)
}
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
