iOS自带定位获取地址
引入框架
#import
遵守代理
<CLLocationManagerDelegate>
需要字段
@property (strong, nonatomic) CLLocationManager *manager;
@property (nonatomic, assign) double currentLatitude;
@property (nonatomic, assign) double currentLongitute;

- (void)viewDidLoad {
[super viewDidLoad];
// 判断定位操作是否被允许
_manager = [[CLLocationManager alloc] init];
[_manager requestWhenInUseAuthorization];//申请定位服务权限
_manager.delegate = self;
//设置定位精度
_manager.desiredAccuracy = kCLLocationAccuracyBest;
//定位频率,每隔多少米定位一次
CLLocationDistance distance = 10.0;//十米定位一次
_manager.distanceFilter = distance;
[_manager startUpdatingLocation];
}
//代理方法
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
NSLog(@"定位成功");
//获取定位的坐标
CLLocation *location = [locations firstObject];
//获取坐标
CLLocationCoordinate2D coordinate = location.coordinate;

//停止定位
[_manager stopUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
