实现代理

定义全局变量

{
    /*** 高德地图 ***/
    MAMapView * _mapView;
    UIButton * _locationButton;
    CLLocation * _currentLocation;
    //主动定位
    AMapSearchAPI * _search;
}

@property(nonatomic,retain)NSString * currentCity;

定义全局宏

//当前城市
#define localTitle @"localTitle"
//当前街道
#define detailTitle @"detailTitle"
//城市id
#define cityId @"cityId"
//获取纬度
#define latitudeLocation @"latitudeLocation"
//获取精度
#define longitudeLocation @"longitudeLocation"
/*** 获取城市城市ID和区域ID ***/
#define getCityUrl @""baseUrl""

定义方法

    ** 高德地图 **
    [self initMapView];
    dispatch_async(dispatch_get_global_queue(0, 0), ^{
        [self initSearch];
    });
