描述

PoiSearch

searchInCity(PoiCitySearchOption option)

城市内检索

PoiSearch

setOnGetPoiSearchResultListener（OnGetPoiSearchResultListener poiResultListener）

设置检索结果回调

PoiCitySearchOption

city(String city)

设置检索城市

PoiCitySearchOption

keyword(String key)

搜索关键字

PoiCitySearchOption

cityLimit(boolean cityLimit)

设置区域数据召回限制 为true时，仅召回city对应区域内数据

重点关注

检索完成后需要调用PoiSearch的destroy()方法，否则会有内存泄露。

核心代码

1.发起检索请求

JAVA

// 发起请求
mPoiSearch.searchInCity((new PoiCitySearchOption())
        .city(cityStr)
        .keyword(keyWordStr)
        .pageNum(mLoadIndex) // 分页编号
        .cityLimit(false)
        .scope(scope));

2.检索结果回调处理

JAVA

@Override
public void onGetPoiResult(PoiResult poiResult) {
    if (poiResult == null || poiResult.error == SearchResult.ERRORNO.RESULT_NOT_FOUND) {
        Toast.makeText(PoiCitySearchActivity.this, "未找到结果", Toast.LENGTH_LONG).show();
        return;
    }

    List<PoiInfo> poiInfos = poiResult.getAllPoi();
    if (null == poiInfos) {
        return;
    }

    // 隐藏之前的
    hidePoiInfoLayout();

    mRecyclerView.setVisibility(View.VISIBLE);

    if (null == mPoiItemAdaper) {
        mPoiItemAdaper = new PoiItemAdapter(poiInfos);
    } else {
        mPoiItemAdaper.updateData(poiInfos);
    }
}

NSString *city

区域名称(必选)

BMKPOICitySearchOption

Bool isCityLimit

区域数据返回限制(可选)

BMKPoiSearch

- (BOOL)poiSearchInCity:(BMKPOICitySearchOption*)option;

发起城市POI检索

BMKPoiSearch

- (void)onGetSuggestionResult:(BMKSuggestionSearch *)searcher result:(BMKSuggestionSearchResult *)result errorCode:(BMKSearchErrorCode)error;

返回Sug检索结果

核心代码

1.发起Sug检索与POI检索

Objective-C

// 根据输入发送sug检索
- (void)searchSugInfoWithKey:(NSString *)key {
    if (key.length == 0) {
        self.sugInfoList = [NSMutableArray array];
        __weak typeof(self) weakSelf = self;
        dispatch_async(dispatch_get_main_queue(), ^{
            [weakSelf.tableView reloadData];
        });
        return;
    }
    
    BMKSuggestionSearchOption *option = [BMKSuggestionSearchOption new];
    option.keyword = key;
    option.cityname = @"北京";
    option.cityLimit = YES;
    
    BMKSuggestionSearch *sugSearch = [BMKSuggestionSearch new];
    sugSearch.delegate = self;
    [sugSearch suggestionSearch:option];

}
/// 根据联想词或关键词进行POI检索
- (void)searchPOIInfoWithKey:(NSString *)key {
    if (!key) {
        return;
    }
    BMKPOICitySearchOption *option = [BMKPOICitySearchOption new];
    option.keyword = key;
    option.city = @"北京";
    option.isCityLimit = YES;

    BMKPoiSearch *search = [BMKPoiSearch new];
    search.delegate = self;
    [search poiSearchInCity:option];
}
#pragma mark - UISearchBarDelegate

// 输入回调
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
    // sug检索
     [self searchSugInfoWithKey:searchText];
}
// 确认检索
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
    // POI检索
    [self searchPOIInfoWithKey:searchBar.text];
}

2.Sug检索回调与POI检索回调

Objective-C

#pragma mark - BMKSuggestionSearchDelegate
/// 返回suggestion搜索结果
/// @param searcher 搜索对象
/// @param result  搜索结果
/// @param error BMKSearchErrorCode
- (void)onGetSuggestionResult:(BMKSuggestionSearch *)searcher result:(BMKSuggestionSearchResult *)result errorCode:(BMKSearchErrorCode)error {
    if (error == BMK_SEARCH_NO_ERROR) {
        self.sugInfoList = [result.suggestionList copy];
        __weak typeof(self) weakSelf = self;
        dispatch_async(dispatch_get_main_queue(), ^{
            [weakSelf.tableView reloadData];
        });
    }
}



#pragma mark - BMKPoiSearchDelegate

/// 返回POI搜索结果
/// @param searcher 搜索对象
/// @param poiResult 搜索结果列表
/// @param errorCode BMKSearchErrorCode
- (void)onGetPoiResult:(BMKPoiSearch *)searcher result:(BMKPOISearchResult *)poiResult errorCode:(BMKSearchErrorCode)errorCode {
    [self.searchView endEditing:YES];
    self.tableView.hidden = YES;
    if (errorCode == BMK_SEARCH_NO_ERROR) {
        if (!poiResult.poiInfoList || poiResult.poiInfoList.count == 0) {
            return;
        }
        // 移除标注
        [_mapView removeAnnotations:_mapView.annotations];
        
        _poiInfoList = [poiResult.poiInfoList copy];
        
        NSMutableArray<BMKPoiAnnotation *> *annotions = [NSMutableArray array];
        for (int i = 0; i < poiResult.poiInfoList.count; i++) {
            BMKPoiInfo *info = poiResult.poiInfoList[i];
            BMKPoiAnnotation *annotaion = [[BMKPoiAnnotation alloc] init];
            annotaion.coordinate = info.pt;
            annotaion.title = info.name;
            annotaion.index = i;
            [annotions addObject:annotaion];
        }
        
        // 添加标注
        [_mapView addAnnotations:annotions];
        // 标注适配屏幕
        [self showAnnotations:annotions animated:YES];
