ios高德地图定位及定位后数据如何回调

我有一个地方需要用到当前的位置的经纬度和省市区（不用显示地图），因此我想封装一个地图类，以后我只要调用这个类就会返回当前的位置的经纬度和省市区。但是操作的时候，一直不调用我的地图，我就不知道该如何做了，望各位指点一二

.h文件

#import <UIKit/UIKit.h>
#import <MAMapKit/MAMapKit.h>
#import <AMapSearchKit/AMapSearchAPI.h>



@interface MyUserLocation : UIViewController


{
    void (^Location)(AMapReGeocode *reGeocode);
}

- (void)location:(void (^)(AMapReGeocode * reGeocode))block;

@end

.m文件

#import "MyUserLocation.h"
#import "Method.h"
#define SPAN  MACoordinateSpanMake(0.025, 0.025)

        [self.userLocationDict setObject:[NSNumber numberWithFloat:userLocation.location.coordinate.latitude] forKey:@"latitude"];
        
        self.currentLocation = userLocation;

3 个解决方案

#1

人工置顶

#2

刚刚UINavigationController推到这个地图类的时候,定位回调居然调用了.这是什么情况呀?如果我这个类不是继承UIViewController,而是继承NSObject,那岂不是永远都不能调用地图了?

#3

需要代理的订阅者去实现地图的代理方法。你上面的控制器中，指明了要实现的协议<MAMapViewDelegate,AMapSearchDelegate>

self.mapView.delegate = self; ///////这句指明了使用当前控制器作为代理的接收者
