swiftui one view with 2 or 3 actionsheets? - swiftui

Question

I want to call different action sheets in a view, using a variable. That does not mean to work.
.actionSheet(isPresented: self.$neuinitialisierung) {
ActionSheet(
title: Text("Testtitel 1"),
message: Text("Testmessage 1"),
buttons: [
.default(Text("Button 1"),
action: {
print("KLICK")
}),
.default(Text("Button 2"),
action: {
self.clouddienst_waehlen = true;
})
])
}
.actionSheet(isPresented: self.$clouddienst_waehlen) {
ActionSheet(
title: Text("Testtitel 2"),
message: Text("Testmessage 2"),
buttons: [
.default(Text("Button 1"),
action: {
print("KLICK")
}),
.default(Text("Button 2"),
action: {
self.clouddienst_waehlen = true;
})
])
}
If I try it with just one action sheet, it works. How can I use the second?

Answer 1

No need for any of these complicated solutions. Just attach your .actionSheets to different views. It doesn’t need to be on the root level. You can use the .actionSheet modifier on a button for example.

I came up with this solution:
#State var showingMenu = false
#State var optionsMenu: OptionsMenu = .main
enum OptionsMenu { case main, export }
...
.actionSheet(isPresented: $showingMenu) {
if self.optionsMenu == .main {
return ActionSheet(title: Text("Main Menu"), buttons: [
.default(Text("Export Menu")) {
delay(0.1) {
self.optionsMenu = .export
self.showingMenu = true
}
}
.destructive(Text("Close"))
])
} else {
return ActionSheet(title: Text("Export Menu"), buttons: [
.default(Text("Export timeline as GPX")) {
// TODO
},
.default(Text("Export timeline as JSON")) {
// TODO
},
.destructive(Text("Close"))
])
}
}
And the button that opens the first menu needs to make sure to reset the enum value, otherwise the wrong menu will open on next button tap:
Button(action: {
self.optionsMenu = .main
self.showingMenu = true
}) {
Image(systemName: "ellipsis")
}

You can use:
func actionSheet<T>(item: Binding<T?>, content: (T) -> ActionSheet) -> some View where T : Identifiable
It takes a Binding to some kind of optional and if the value is not nil presents an ActionSheet. Instead of setting your a flag to true, you would set this optional to some value.
