在使用高德地图之前需要现在高德地图开放平台创建一个APP，会自动生成一个appKey，在工程中使用高德地图sdk时是需要这个key的，然后在自己的工程导入高德地图sdk，高德地图开放平台上有详细的步骤。
1、引入需要的地图框架
#import <MAMapKit/MAMapKit.h>
#import <AMapFoundationKit/AMapFoundationKit.h>
#import <AMapSearchKit/AMapSearchKit.h>
#import <AMapLocationKit/AMapLocationKit.h>
2、创建地图以及需要的属性
//地图
self.mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 0, kScreenWidth, kScreenHeight)];
self.mapView.delegate = self; //遵循代理<MAMapViewDelegate>
[self.view addSubview:self.mapView];
//定位
self.locationManager = [[AMapLocationManager alloc] init];
self.locationManager.delegate = self; //遵循代理<AMapLocationManagerDelegate>
[self.locationManager startUpdatingLocation];//开始定位
//逆地理编码回调
self.regeo = [[AMapReGeocodeSearchRequest alloc] init];
self.searchPoi = [[AMapSearchAPI alloc] init];
self.searchPoi.delegate = self; //遵循代理<AMapSearchDelegate>
//设置地图中间的图片
if (self.centerImgView == nil)
{
self.centerImgView = [[UIImageView alloc] initWithFrame:CGRectMake((kScreenWidth-20)/2, (kScreenHeight-37)/2, 20, 37)];
self.centerImgView.image = [UIImage imageNamed:@"anno"];
}
[self.mapView addSubview:self.centerImgView];
//设置button，显示当前定位的地址（也可以用Label，因为别的功能需要它的点击事件）
self.poiButton = [[UIButton alloc] initWithFrame:CGRectMake(20, 40, kScreenWidth-40, 40)];
self.poiButton.backgroundColor = [UIColor colorWithRed:248/255.0 green:252/255.0 blue:255/255.0 alpha:1];
self.poiButton.layer.masksToBounds = YES;
self.poiButton.layer.cornerRadius = 20.0;
[self.poiButton setTitleColor:[UIColor blackColor] forState:(UIControlStateNormal)];
[self.mapView addSubview:self.poiButton];
3、定位代理方法
- (void)amapLocationManager:(AMapLocationManager *)manager didUpdateLocation:(CLLocation *)location
{
//定位结果
NSLog(@"当前经纬度：location:{lat:%f; lon:%f}", location.coordinate.latitude, location.coordinate.longitude);
//将当前经纬度设置为地图的中心经纬度
self.mapView.centerCoordinate = location.coordinate;
//因为这个是后台持续定位的代理方法，所以必须停止定位，否则地图只要一移动就会回到当前所在位置。
//因为一进入地图就会定位，延迟1s停止定位，是为了能够精准的获取到当前位置，否则可能会出现你定位在当前位置了，但是button上显示的却是别的地方的位置
double delayInSeconds = 1.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
//执行事件
[self.locationManager stopUpdatingLocation];//停止定位
});
}
4、地图区域改变完成后会调用此接口（挪动地图改变经纬度）
- (void)mapView:(MAMapView *)mapView regionDidChangeAnimated:(BOOL)animated;
{
self.centerCoor = [self.mapView convertPoint:self.mapView.center toCoordinateFromView:self.mapView];
//开始逆地理编码，把当前经纬度转成中文地址
self.regeo.location = [AMapGeoPoint locationWithLatitude:self.centerCoor.latitude longitude:self.centerCoor.longitude];
[self.searchPoi AMapReGoecodeSearch:self.regeo];
}
5、逆地理编码回调
- (void)onReGeocodeSearchDone:(AMapReGeocodeSearchRequest *)request response:(AMapReGeocodeSearchResponse *)response
{
if (response.regeocode != nil)
{
//解析response获取地址描述，可以自行选取需要的信息
// self.nowStr 是由当前经纬度转化的中文地址
self.nowStr = [NSString stringWithFormat:@"%@%@%@%@", response.regeocode.addressComponent.province, response.regeocode.addressComponent.city, response.regeocode.addressComponent.district, response.regeocode.addressComponent.streetNumber.street];
;
NSLog(@"💖%@", self.nowStr);
[self.poiButton setTitle:self.nowStr forState:(UIControlStateNormal)];
}
}
上面用到的属性（忘记写在上面了，就补在这里）
@property (strong, nonatomic) MAMapView *mapView;
@property (strong, nonatomic) AMapLocationManager *locationManager;
@property (strong, nonatomic) AMapSearchAPI *searchPoi;
@property (strong, nonatomic) AMapReGeocodeSearchRequest *regeo;
//显示中心点经纬度的地址
@property (strong, nonatomic) UIButton *poiButton;
//当前位置地址
@property (strong, nonatomic) NSString *nowStr;
//中心点大头针
@property (strong, nonatomic) UIImageView *centerImgView;
//中心点经纬度结构体
//这个就是当前地图中心店的经纬度，如果需要使用这个经纬度，可以直接用这个属性
@property (assign, nonatomic) CLLocationCoordinate2D centerCoor;
