SwiftUI的 context Menu

现在来演示一下如何使用 SwiftUI 的 Context Menu 。
代码：

import SwiftUI

struct ContextMenuBootCamp: View {
    @State var bgColor: Color = .purple
    var body: some View {
        VStack(alignment: .leading, spacing: 10.0) {
            Image(systemName: "house.fill")
                .font(.title)
            Text("Swiftful Thinking")
                .font(.headline)
            Text("how to use context menu".localizedCapitalized)
                .font(.subheadline)
        }
        .foregroundColor(.white)
        .padding(30)
        .background(bgColor)
        .cornerRadius(30)
        .contextMenu(ContextMenu(menuItems: {
            Button(action: {
                bgColor = .red
            }, label: {
                Label("Button #1", systemImage: "flame.fill")
            })
            Button(action: {
                bgColor = .orange
            }, label: {
                Label("Button #2", systemImage: "flame.fill")
            })
            Button(action: {
                bgColor = .green
            }, label: {
                Label("Button #3", systemImage: "flame.fill")
            })
        }))
        
    }
}

#Preview {
    ContextMenuBootCamp()
