[SUI] 表单 (Form)

Form

Form 是一个用于分组控件的容器，主要用于某些功能的配置。
它以 grouped 样式的 List 展示控件，并在四周留有填充。
与 List 组件类似，Form 也可以使用 Section 将内容分成多个部分。

示例

enum NotifyMeAboutType {
    case directMessages, mentions, anything
}

enum ProfileImageSize {
    case large, medium, small
}

struct ContentView: View {
    @State private var notifyMeAbout: NotifyMeAboutType = .anything
    @State private var playNotificationSounds = false
    @State private var sendReadReceipts = false
    @State private var profileImageSize: ProfileImageSize = .small

    var body: some View {
        NavigationView {
            Form {
                Section(header: Text("Notifications"),
                        footer: Text("¿Qué quieres que te notifique?")) {
                    Picker("Notify Me About", selection: $notifyMeAbout) {
                        Text("Direct Messages").tag(NotifyMeAboutType.directMessages)
                        Text("Mentions").tag(NotifyMeAboutType.mentions)
                        Text("Anything").tag(NotifyMeAboutType.anything)
                    }
                    Toggle("Play notification sounds", isOn: $playNotificationSounds)
                    Toggle("Send read receipts", isOn: $sendReadReceipts)
                }
                Section(header: Text("User Profiles")) {
                    Picker("Profile Image Size", selection: $profileImageSize) {
                        Text("Large").tag(ProfileImageSize.large)
                        Text("Medium").tag(ProfileImageSize.medium)
                        Text("Small").tag(ProfileImageSize.small)
                    }
                    Button("Clear Image Cache") {}
                }
            }
        }
    }
}
