高级地点搜索组件

这是一个专业版组件，其结算方式与基本版组件不同。如需了解详情，请参阅概览。

高级版“地点搜索”组件提供的功能与地点搜索基础版相同。您还可以配置该组件的操作按钮，并对显示的评价和媒体应用搜索和过滤选项。

高级地点搜索配置

使用 AdvancedPlaceSearchView 访问高级功能。

配置操作按钮

使用 AdvancedPlaceSearchView 的 .cornerActions 和 .mainActions 方法可移除或自定义操作按钮。

视觉提供方信息要求

带有自定义按钮的地点搜索结果

重要提示：当自定义操作按钮会将用户信息分享给 Google 以外的第三方时，您必须明确告知用户。请参阅视觉提供方信息要求。

此示例展示了一个自定义图片，该图片明确表明用户的信息将发送给“Altostrat”。

应用搜索和过滤选项

使用 AdvancedPlaceSearchView 的 .searchMediaOptions 和 .searchReviewOptions 方法可为媒体或评价启用搜索和过滤功能。

高级地点搜索示例

创建主要操作按钮并移除边角操作

此代码示例会创建一个用于收藏或取消收藏地点的主要操作按钮。它还可确保未配置任何边角操作。

Swift

struct AdvancedPlaceSearchDemoView: View {
  private let configuration = AdvancedPlaceSearchConfiguration(
    content: [.address(), .rating(), .type()],
    preferTruncation: true, // default is false
    theme: PlacesMaterialTheme(),
    attributionPosition: .bottom, // default is top
    mediaSize = .medium, // default is .small
    selectable: true // default is false
  )
  // can also do let placeSearchViewRequest = .searchNearby(...) to  configure a searchNearby request
  @State private var placeSearchViewRequest = .searchByText(
    SearchByTextRequest(
      textQuery: "Googleplex",
      placeProperties: [.all],
      locationBias: CircularCoordinateRegion(
        center: CLLocationCoordinate2D(latitude: 0, longitude: 0),
        radius: 0
      )
    )
  )

  @State private var favoritePlaces: Set<String> = []

  var body: some View {
    AdvancedPlaceSearchView(
      orientation: .horizontal, // default is vertical
      request: placeSearchViewRequest,
      configuration: configuration
    )
    .onLoad { places in
      print("places: \(places)")
    }
    .onRequestError { error in
      print("error: \(error)")
    }
    .onPlaceSelected { place, index in
      print("place: \(place)")
      print("index: \(index)")
    }
    .mainActions { place in
      var actions: [MainPlaceActionElement] = []

      let placeID = place.placeID!
      if self.favoritePlaces.contains(placeID) {
        actions.append(
          .action(
            MainPlaceAction(
              image: Image(systemName: "heart.fill"),
              label: "Unfavorite"
            ) { _ in self.toggleFavorite(placeID) }
          )
        )
      } else {
        actions.append(
          .action(
            MainPlaceAction(
              image: Image(systemName: "heart"),
              label: "Favorite"
            ) { _ in self.toggleFavorite(placeID) }
          )
        )
      }
      actions.append(.actionId(.openMap(style: .primary)))
      return actions
    }
    // Ensures that there are no corner actions.
    .cornerActions { _ in
      return []
    }
  }

  func toggleFavorite(_ placeID: String) {
    if favoritePlaces.contains(placeID) {
      favoritePlaces.remove(placeID)
    } else {
      favoritePlaces.insert(placeID)
    }
  }
}

        

过滤评价和媒体内容

此代码示例会过滤搜索结果，仅显示提及“咖啡”的媒体和评价。

Swift

struct DemoView: View {
  static let peetsCoffeePlaceID = "ChIJT7FdmYiAhYAROFOvrIxRJDU"

  // Query for loading the place details component.
  @State var query: PlaceDetailsQuery = PlaceDetailsQuery(
    identifier: .placeID(peetsCoffeePlaceID)
  )
  let searchMediaOptions = SearchMediaOptions(query: "coffee", rankPreference: .newest)
  let searchReviewOptions = SearchReviewsOptions(query: "coffee", rankPreference: .newest)

  var body: some View {
    AdvancedPlaceDetailsView(
      query: $query,
      configuration: AdvancedPlaceDetailsConfiguration(
        content: [.media(), .reviews()],
        theme: PlacesMaterialTheme()
      ),
      placeDetailsCallback: { _ in }
    )
    .searchMediaOptions(searchMediaOptions) { results in
      guard let result = results.first else { return }
      switch result {
      case .success(let summary):
        print("Summary: \(summary)")
      case .failure(let error):
        print("Error: \(error)")
      }
    }
    .searchReviewsOptions(searchReviewsOptions) { results in
      guard let result = results.first else { return }
      switch result {
      case .success(let summary):
        print("Summary: \(summary)")
      case .failure(let error):
        print("Error: \(error)")
      }
    }
  }
