SwiftUI:无法将“Bool"类型的值转换为预期的参数类型“Binding<Bool>" [英] SwiftUI: Cannot convert value of type 'Bool' to expected argument type 'Binding<Bool>'

问题描述

为 SwiftUI 创建一个基于文本的游戏

Creating a text-based game for SwiftUI

想知道为什么我不能在字符 ForEach 循环中访问 isSelected?

Wondering why can't I access isSelected in character ForEach loop?

收到此错误:无法将Bool"类型的值转换为该行上的预期参数类型Binding"

Get this error: Cannot convert value of type 'Bool' to expected argument type 'Binding' on this line

Toggle(isOn: character.isSelected){

变量对象声明:@Binding var 字符:[字符]

代码在这里:

        VStack {

            ForEach(characters) { character in

                HStack{

                    VStack(alignment:.leading) {
                        Text("\(character.name)")
                            .fontWeight(.bold)

                        Text("\(character.description)")
                        .lineLimit(10)

                    }

                    Spacer()

                    Toggle(isOn: character.isSelected){
                        Text("a")
                    }.labelsHidden()

推荐答案

你只需要添加一个 $:

You just need to add a $:

Toggle(isOn: $character.isSelected){
