搜尋建議

取得建議搜尋

如要取得搜尋建議，請對 ContextualSearchRuntime 呼叫 getSearchSuggestions 方法。這個方法會採用單一 GetSearchSuggestionsOptions，您可以在其中指定要用來取得搜尋建議的文字。

傳回的 SearchSuggestions 物件不含任何可存取的屬性。其中包含轉譯搜尋建議所需的一切資訊，但沒有公開透明。

Swift 使用 Swift 並行處理樣式，Objective-C 則使用回呼函式。

Swift

getSearchSuggestions(withOptions:)

Task {
    let suggestions = try await searchRuntime.getSearchSuggestions(
            withOptions: GetSearchSuggestionsOptions(withTextContext:['Sample Query', 'Another query string']))
}

Objective-C

getSearchSuggestionsWithOptions

  [searchRuntime
      getSearchSuggestionsWithOptions:
            [[GetSearchSuggestionsOptions alloc] initWithTextContext: @[@'Sample Query', @'Another query string' ]]
                             completionHandler:^(SearchSuggestions *_Nullable suggestions,
                                                 NSError *_Nullable error) {
                              // error will be not null if there is an error.
                              // On success, suggestions will be non null.
                            }];

取得依據位置提供的搜尋建議

getSearchSuggestions 要求也支援根據位置提供搜尋建議。使用 LocationSuggestionsContext 建構 GetSearchSuggestionsOptions 物件。

請按照下列步驟建構 LocationSuggestionsContext 類別：

1. (必要) 設定 latitude、longitude 和 radiusMeters，以符合要求的區域。
2. (選用) 將 startTime 設為符合應套用的搜尋建議要求時間。
3. (選用) 設定 geoTypes 清單，其中包含要求的地理區域類型。提供的類型可用於調整服務傳回結果的排名和篩選方式。支援的值列於 LocationSuggestionsContext。

Swift

getSearchSuggestions(withOptions:)

Task {
    let locationContext: LocationSuggestionsContext = {
      let context = LocationSuggestionsContext()
      context.latitude = 40.748595
      context.longitude = -73.992365
      context.radiusMeters = 2500
      context.startTime = try?
        Date.ISO8601FormatStyle.iso8601.parse("2024-03-14T19:20:30.000+02:00")
      context.geoTypes = ["restaurant", "cafe"]
      return context
    }()
    let suggestions = try await searchRuntime.getSearchSuggestions(
            withOptions: GetSearchSuggestionsOptions(locationContext: [
              locationContext
            ]))
}

Objective-C

getSearchSuggestionsWithOptions

  LocationSuggestionsContext *locationContext;
  locationContext = [[LocationSuggestionsContext alloc] init];
  locationContext.latitude = 40.748595;
  locationContext.longitude = -73.992365;
  locationContext.radiusMeters = @2500;
  [searchRuntime
      getSearchSuggestionsWithOptions:
            [[GetSearchSuggestionsOptions alloc] initWithLocationContext: locationContext]
                             completionHandler:^(SearchSuggestions *_Nullable suggestions,
                                                 NSError *_Nullable error) {
                              // error will be not null if there is an error.
                              // On success, suggestions will be non null.
                            }];

多媒體

如要顯示搜尋建議方塊，請使用下列方法 (如果使用 UIKit 與 SwiftUI，樣式會有所不同)。

Swift UIKit

使用 SearchSuggestionsViewController 顯示搜尋建議方塊。

// Create the SearchSuggestionsViewController with specified display options.
var searchSuggestionsController = SearchSuggestionsViewController(options: viewOptions)
...
// Add the view controller to the existing view hierarchy
searchSuggestionsController.addToViewContoller(self)
view.addSubview(searchSuggestionsController.view)
...
// Assign a specific set of search suggestions to this view controller.
searchSuggestionsController.searchSuggestions = suggestions

Objective-C

使用 SearchSuggestionsViewController 顯示搜尋建議方塊。

// Create the SearchSuggestionsController with specified display options.
SearchSuggestionsViewController *_searchSuggestionsController =
      [[SearchSuggestionsViewController alloc] initWithOptions:_customizationOptions];
...
// Add the view controller to the existing view hierarchy
[_searchSuggestionsController addToViewController:self];
[self.view addSubview:_searchSuggestionsController.view];
...
// Assign a specific set of search suggestions to this view controller.
_searchSuggestionsController.searchSuggestions = suggestions

SwiftUI

您可以使用 SearchSuggestionsView 顯示搜尋建議

SearchSuggestionsView(suggestions: suggestions, options: options)
