项目需求

1.公司要求模仿微信/QQ的定位选址效果
2.根据关键字进行定位选址
本项目中用到了高德地图的POI周边搜索功能、单次定位功能、关键字搜索

本人对高德的API进行了一个简单的封装,SLocationManager定位管理者,可以进行单次搜索,持续搜索,关键字搜索,获取当前的经纬度...如果有什么不明白的地方直接看官方文档,文档真的很详细,注释什么的很详细,这个工具类是直接从项目中拷贝过来的,由于工作时间紧张,所以没有demo,😂,小伙伴们不要问demo了,哈哈.👇的快速通道可以帮助小伙伴们快速熟悉高德API,如果有什么疑问,欢迎提问

快速通道

1.根据关键字检索POI（Point of Interest，兴趣点)

关键字检索介绍

根据关键字检索适用于在某个城市搜索某个名称相关的POI，例如：查找北京市的“肯德基”。
注意：关键字未设置城市信息（默认为全国搜索）时，如果涉及多个城市数据返回，仅会返回建议城市，请根据APP需求，选取城市进行搜索。

2.检索周边POI

周边检索介绍

适用于搜索某个位置附近的POI，可设置POI的类别，具体查询所在位置的餐饮类、住宅类POI，例如：查找天安门附近的厕所等等场景。
****说明****：

1、支持指定查询POI的类别。高德地图的POI类别共20个大类，分别为：汽车服务、汽车销售、汽车维修、摩托车服务、餐饮服务、购物服务、生活服务、体育休闲服务、医疗保健服务、住宿服务、风景名胜、商务住宅、政府机构及社会团体、科教文化服务、交通设施服务、金融保险服务、公司企业、道路附属设施、地名地址信息、公共设施，同时，每个大类别都还有二级以及三级的细小划分，具体的POI类别请参考：POI分类编码表。
2、不设置POI的类别，默认返回“餐饮服务”、“商务住宅”、“生活服务”这三种类别的POI。

陌上北辰:我想问下，为什么（-(void)onInputTipsSearchDone:(AMapInputTipsSearchRequest *)request response:(AMapInputTipsSearchResponse *)response）我每次返回的数据都只有10条呢，可以设置吗
HaoKe:// 设置每页最多返回多少条poiitem
query.setPageSize(30);
HaoKe:int currentPage = 0;
//不输入城市名称有些地方搜索不到
// 第一个参数表示搜索字符串，第二个参数表示poi搜索类型，第三个参数表示poi搜索区域（空字符串代表全国）
query = new PoiSearch.Query(key, "", "");
// 设置每页最多返回多少条poiitem
query.setPageSize(30);
// 设置查询页码
query.setPageNum(currentPage);

//构造 PoiSearch 对象，并设置监听
poiSearch = new PoiSearch(this, query);
poiSearch.setOnPoiSearchListener(this);
//调用 PoiSearch 的 searchPOIAsyn() 方法发送请求。
poiSearch.searchPOIAsyn();
CoderZNB:@陌上北辰我记得可以的，文档里有说
1ffdfbe42a4c:您好！想问下现在有demo么？或者帮助一下qq：946608155，万分感谢！
1ffdfbe42a4c:@CoderZNB 而且我的需求几乎跟楼主的一模一样，所以希望楼主能多给一些帮助，我卡在这两天了
1ffdfbe42a4c:@CoderZNB 我集成啥的都成功了，但是咋就出不来列表呢，而且还竟然走if (self.canLocationFlag == NO) {
return ;
}这个了，这个不是没定位成功么
CoderZNB:没有demo啊,你走到哪一步了
CodeMe:请问AMapPOIAroundSearchRequest支持拼音搜索吗
CoderZNB:@CodeMe 那你就得在返回的结果里处理了，遍历所有的结果，使用属性字符串，给关键字设置高亮
CodeMe:@CoderZNB 如何像微信那样，将包含关键字的部分高亮，即使用拼音也可以
CoderZNB:可以的
Locaus_Joe:请问我调用了[[SLocationManager sharedManager] beginAroundSearch],没有返回周围搜索的数据呢？
Locaus_Joe:@ZNBmm 是的已经弄好 666
CoderZNB: @Locaus_Joe - (void)locationManagerDidGetPOISearchResponse，这个方法里返回了，如果我没记错的话😬
916648890dfa:6666
Vampire_Jam:真不赖啊你
