ios获取当前城市 ,位置,坐标,经纬度

有些时候可能只是用到地图的某些功能,比如获取当前所在的城市,然后根据城市返回相应的数据,而不需要其他操作,每次都要写那么几行代码,所以就做了小小的封装,后期可能会添加新功能,来适应app的各种需求(使其变得更为强大)

github打包地址:https://github.com/iOSSinger/SGLocation

核心代码:

使用方法:

    //一行代码获取当前城市
    [loc setGetCity:^(NSString *city) {
        NSLog(@"%@",city);
    }];

    //一行代码获取当前位置
    [loc setGetLocation:^(NSString *location) {
        NSLog(@"%@",location);
    }];

    //一行代码获取当前坐标
    [loc setGetCoordinate:^(CLLocationCoordinate2D coodinate) {
        NSLog(@"%f-%f",coodinate.latitude,coodinate.longitude);
    }];

具体实现代码,其实用block将值传回来,而不需要使用代理

#import "SGLocation.h"

@interface SGLocation()<CLLocationManagerDelegate>

@property (nonatomic,strong) CLLocationManager *manager;
