SwiftUI带主操作Popup按钮跨平台适配：Mac右键无菜单求助

问题核心在于Mac平台上，Menu组件的primaryAction会将右键点击也触发为主操作，而非弹出菜单。要实现跨平台的「点击触发主操作、长按/右键弹出菜单」效果，最简易的方案是使用**Button配合contextMenu**的组合，这种方式在iOS（长按）和Mac（右键）上都能稳定工作：

struct ContentView: View {
    var body: some View {
        Button {
            print("Button was tapped")
        } label: {
            Label("Options", systemImage: "paperplane")
        }
        .buttonStyle(.borderless)
        .contextMenu {
            Button("Item One", action: {})
            Button("Item Two", action: {})
            Button("Item Three", action: {})
        }
    }
}

方案说明： #

• iOS端：长按按钮会弹出上下文菜单，点击按钮触发主操作，和原Menu的primaryAction表现完全一致。
• Mac端：左键点击触发主操作，右键点击弹出菜单，完美匹配需求。

如果想在iOS上保留原Menu的展开动画等原生体验，也可以通过平台条件编译区分处理：

struct ContentView: View {
    var body: some View {
        #if os(iOS)
        Menu {
            Button("Item One", action: {})
            Button("Item Two", action: {})
            Button("Item Three", action: {})
        } label: {
            Label("Options", systemImage: "paperplane")
        } primaryAction: {
            print("Button was tapped")
        }
        .buttonStyle(.borderless)
        #else
        Button {
            print("Button was tapped")
        } label: {
            Label("Options", systemImage: "paperplane")
        }
        .buttonStyle(.borderless)
        .contextMenu {
            Button("Item One", action: {})
            Button("Item Two", action: {})
            Button("Item Three", action: {})
        }
        #endif
    }
}
