文章标签 android高德地图选点地图高德地图搜索初始化 文章分类 Android 移动开发

这两天一直捣鼓着地图的选址功能，需要达到的要求是：1，能用户定位 2，大头针固定在地图中心，拖动地图停止后获取到该大头针的位置信息 3，能通过搜索框搜索到我们输入的地址

主要思路：大头针分为两个一个是用户的位置大头针另一个是所选取的位置的大头针（包括拖动后的大头针和搜索功能查找到位置的大头针，公用一个大头针）并且两个大头针都成为控制器器属性。

我使用到的高德地图sdk是:

'AMap3DMap' , '5.2.1' #高德3D地图

'AMapSearch' , '5.2.1' #高德搜索功能

'AMapLocation', '2.4.0' #定位

完整代码如下：

#define Screen_Width        [UIScreen mainScreen].bounds.size.width
#define Screen_Height       [UIScreen mainScreen].bounds.size.height

@interface MapAddressViewController ()<MAMapViewDelegate, AMapSearchDelegate, UISearchBarDelegate, UISearchResultsUpdating, UITableViewDataSource, UITableViewDelegate, AMapLocationManagerDelegate>


///定位
@property (nonatomic, strong) AMapLocationManager *locationManager;
///定位按钮
@property(nonatomic,weak) UIButton *locationBtn;
///搜索  控制器
@property (nonatomic, strong) UISearchController *searchController;
///展示搜索结果tableView
@property (nonatomic, strong) UITableView *tableView;
///搜索提示  模型
@property (nonatomic, strong) NSMutableArray *tips;
///地图
@property (nonatomic, strong) MAMapView *mapView;
///大头针
@property (nonatomic, strong) MAPointAnnotation *pointAnnotation;
///大头针view视图
@property(nonatomic, strong) MAAnnotationView *annotationView;
///逆地理编码
@property (nonatomic, strong) AMapReGeocodeSearchRequest *regeo;
///逆地理编码使用的
@property (nonatomic, strong) AMapSearchAPI *search;
///单次定位的回调
@property (nonatomic, copy) AMapLocatingCompletionBlock completionBlock;
//显示地址的label
@property(nonatomic, weak) UILabel *addressL;

@end

上面获取到的信息是一个位置的具体信息，如果你想获取就近的POI信息，可以在地图结束拖动的代理做如下操作：

/**
 滑动地图结束 修改当前位置
 */
- (void)mapView:(MAMapView *)mapView regionDidChangeAnimated:(BOOL)animated {
//    self.regeo.location = [AMapGeoPoint locationWithLatitude:mapView.centerCoordinate.latitude longitude:mapView.centerCoordinate.longitude];
    AMapPOIAroundSearchRequest *r = [[AMapPOIAroundSearchRequest alloc] init];
    r.location = [AMapGeoPoint locationWithLatitude:mapView.centerCoordinate.latitude longitude:mapView.centerCoordinate.longitude];
    r.radius = 500; //查找半径 单位:米
    r.sortrule = 0; // 排序: 0距离  1综合
//    r.types = @"写字楼|公寓|建筑|餐饮"; //搜索的类型 多个用'|'分割
    [self.search AMapPOIAroundSearch:r];
//    [self.search AMapReGoecodeSearch:self.regeo];
    
    if (self.annotationView) {
        
        [UIView animateWithDuration:0.15 animations:^{
            self.annotationView.centerOffset = CGPointMake(0, -18 + offsetY);
        }];
    }
}

然后在poi查找结果回调中获得数据:

/**
 * @brief POI查询回调函数
 * @param request  发起的请求，具体字段参考 AMapPOISearchBaseRequest 及其子类。
 * @param response 响应结果，具体字段参考 AMapPOISearchResponse 。
 */
- (void)onPOISearchDone:(AMapPOISearchBaseRequest *)request response:(AMapPOISearchResponse *)response{


    for (AMapAOI *poi in response.pois) {
        NSLog(@"%@",poi.name);
    }

}

提醒我自己: 1, 添加搜索栏的时候如果直接用Masonry添加约束, 刚进控制器那会儿还正常, 但是一点击搜索, 搜索栏就会跑到屏幕外(左上角屏幕之外)。解决办法是添加一个父控件，然后再将搜索栏用frame的形式添加到父控件。2，创建后的选取位置的大头针视图(是视图不是模型) 用属性保存起来在地图即将拖动和拖动完成后的代理通过改变 centerOffset 来让大头针有动画效果(当然,也有其他方法可实现) 3,
