如何从 swiftUI 的父视图中的另一个视图访问变量？

Question

I have one view "CancelRow"

struct CancelRow: View {
    @State var isSelected: Bool = true // its dynamic

//UI part
}

I have another view i which i want to show button active or not based on "isSelected" from "CancelRow"

// AnotherVIew

    Spacer()
    SubmitButtonView(buttonTitle: title, buttonCallBack: {
        goToOtherScreen()
    }, isActive: isSelected ) // how to access this variable from  "CancelRow"

but i am not sure how to access variable from another view..and if value of "isSelected" is changed in "CancelRow" how to update that value in another view?

Thank you for help

Answer 1

If the relationship beetween your views is "parent" (or composition ), then you can use @Binding property wrapper. Then your SubmitButtonView will have a property

@Binding var isActive: Bool 

and you'll call

SubmitButtonView(buttonTitle: title, buttonCallBack: {
        goToOtherScreen()
    }, isActive: $isSelected )

from CancelRow .
