iOS 高德地图仿微信发送实时位置 - IOS - 服务器之家

这篇文章主要介绍了iOS 高德地图仿微信发送实时位置,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧

最近项目中要写一个微信那种发送位置的功能。具体功能在于:

- 定位到当前位置

- 可定位当前位置附近的poi

- 可自行搜索目标位置,并展示附近的poi

- 选择当前位置或者选择目标位置进行发送

iOS 高德地图仿微信发送实时位置

一.准备工作

1.首先去高德地图官网下载相关的sdk(如下图):

2.按照高德地图官网的步骤继续添加所需要的依赖库

3.根据项目的bundleid前往高德地图api中创建引用并申请相关的key

高德地图应用管理后台

到这一步前期的准备工作基本差不多了,当然,我这写的不是很具体,详细的引入高德地图sdk还需要耐心按照高德地图官网sdk一步步的去操作

二.代码部分

1.初始化高德地图sdk

在appledelegate中引入相关头文件,从高德地图应用管理中找到该应用对用的key值,进行高德地图sdk的初始化操作。直接贴代码部分:

  self.window.rootviewcontroller = [[uinavigationcontroller alloc] initwithrootviewcontroller:[viewcontroller new]];
  [amapservices sharedservices].apikey = apikey;
  
  return yes;
}

2.定位到用户当前位置

在你需要定位的类中引入与地图相关的头文件

初始化地图view:

    if (error) {
      [self showhint:@"定位错误" yoffset:-180];
      nslog(@"locerror:{%ld - %@};",(long)error.code,error.localizeddescription);
      if (error.code == amaplocationerrorlocatefailed) {
        return ;
      }
    }
    //定位信息
    nslog(@"location:%@", location);
    if (regeocode)
    {
      [self hidehud];
      self.currentlocationcoordinate = cllocationcoordinate2dmake(location.coordinate.latitude, location.coordinate.longitude);
      self.city = regeocode.city;
      [self showmappoint];
      [self setcenterpoint];
      self.request.location = [amapgeopoint locationwithlatitude:location.coordinate.latitude longitude:location.coordinate.longitude];
      [self.mapsearch amappoiaroundsearch:self.request];
    }
  }];
}

定位成功之后展示大头针到当前位置(如果一直不显示大头针,检查一下自己是否导入了高德地图的资源文件):

    self.request.page = self.currentpage;
    [self.mapsearch amappoiaroundsearch:self.request];

}

包括主动选择地图上的点然后进行附近的搜索,可自定义搜索的内容,定位成功之后用户可以获取到当前的经纬度地址等一系列信息。详细的代码有点多就不一一贴出来了,需要的同学可以点击下面的github地址去下载体验。
