swiftui dismiss view
Using @State property wrapper (recommended)
struct ContentView: View {
@State private var showModal = false
var body: some View {
Button("Show Modal") {
self.showModal.toggle()
}.sheet(isPresented: $showModal) {
ModalView(showModal: self.$showModal)
}
}
}
struct ModalView: View {
@Binding var showModal: Bool
var body: some View {
Text("Modal view")
Button("Dismiss") {
self.showModal.toggle()
}
}
}
Using presentationMode
You can use presentationMode environment variable in your modal view and calling self.presentaionMode.wrappedValue.dismiss() to dismiss the modal:
struct ContentView: View {
@State private var showModal = false
// If you are getting the "can only present once" issue, add this here.
// Fixes the problem, but not sure why; feel free to edit/explain below.
@Environment(\.presentationMode) var presentationMode
var body: some View {
Button(action: {
self.showModal = true
}) {
Text("Show modal")
}.sheet(isPresented: self.$showModal) {
ModalView()
}
}
}
struct ModalView: View {
@Environment(\.presentationMode) private var presentationMode
var body: some View {
Group {
Text("Modal view")
Button(action: {
self.presentationMode.wrappedValue.dismiss()
}) {
Text("Dismiss")
}
}
}
}
