ActionSheet 列表提示框的使用

1. ActionSheet 的基本使用

  1.1 实现

 /// 列表提示框
struct ActionsheetBootcamp: View {
    @State var showActionSheet: Bool = false
    @State var actionSheetOption: ActionSheetOptions = .isOtherPost
    
    /// 定义枚举
    enum ActionSheetOptions{
        case isMyPost
        case isOtherPost
    }
    
    var body: some View {
        testView1
        //testView2
        //testView3
    }
    
    /// 方式一 基本使用
    var testView1: some View{
        Button("Click me") {
            showActionSheet.toggle()
        }
        .actionSheet(isPresented: $showActionSheet, content: getActionSheet1)
    }
    
    func getActionSheet1() -> ActionSheet{
        return ActionSheet(title: Text("This is title"))
    }
}

  2.1 实现

// 方式二 带有标题，内容和多个 Button
var testView2: some View{
    VStack {
        HStack {
            Circle()
                .frame(width: 30, height: 30)
            Text("@username")
            Spacer()
            Button {
                showActionSheet.toggle()
            } label: {
                Image(systemName: "ellipsis")
            }
            .accentColor(.primary)
        }
        .padding()
        Rectangle().aspectRatio(1.0, contentMode: .fit) //aspectRatio: 纵横比 fit: 缩放自适应
    }
    .actionSheet(isPresented: $showActionSheet, content: getActionSheet2)
}

// 创建表单提示框
func getActionSheet2() -> ActionSheet{
    //return ActionSheet(title: Text("This is title"))
    let button1: ActionSheet.Button = .default(Text("Default"))
    let button2: ActionSheet.Button = .destructive(Text("Destructive"))
    let button3: ActionSheet.Button = .cancel()
    return ActionSheet(
        title: Text("This is the title!"),
        message: Text("This is the message."),
        buttons: [button1, button2, button3])
}

3. ActionSheet 枚举分类型提示框

  3.1 实现

// 方式三 枚举分类型
var testView3: some View{
    VStack {
        HStack {
            Circle()
                .frame(width: 30, height: 30)
            Text("@username")
            Spacer()
            Button {
                actionSheetOption = .isMyPost
                showActionSheet.toggle()
                
            } label: {
                Image(systemName: "ellipsis")
            }
            .accentColor(.primary)
        }
        .padding()
        Rectangle().aspectRatio(1.0, contentMode: .fit) //aspectRatio: 纵横比 fit: 缩放自适应
    }
    .actionSheet(isPresented: $showActionSheet, content: getActionSheet3)
}

// 创建表单提示框
func getActionSheet3() -> ActionSheet{
    let shareButton: ActionSheet.Button = .default(Text("Share")) {
        // add code to share post
    }
    let reportButton: ActionSheet.Button = .destructive(Text("Report")) {
        // add code to report this post
    }
    let deleteButton: ActionSheet.Button = .destructive(Text("Delete")) {
        // add code to delete this post
    }
    let cancelButton: ActionSheet.Button = .cancel()
    
    let title: String = "What woud you like to do?"
    
    switch actionSheetOption{
    case .isOtherPost:
        return ActionSheet(
            title: Text(title),
            message: nil,
            buttons: [shareButton, reportButton, cancelButton])
    case .isMyPost:
        return ActionSheet(
            title: Text(title),
