1、注：info.plist里面加NSLocationWhenInUseUsageDescription（string）类型
iOS10之后在plist里面加：
定位权限：Privacy - Location When In Use Usage Description 我们需要通过您的地理位置信息获取您周边的相关数据
定位权限: Privacy - Location Always Usage Description 我们需要通过您的地理位置信息获取您周边的相关数据
定位的需要这么写，防止上架被拒。
2、添加Framework

#import <CoreLocation/CoreLocation.h>

3、添加代理，属性

<CLLocationManagerDelegate>
@property (nonatomic, strong) CLLocationManager *locationManage;
@property (nonatomic, assign) CLLocationCoordinate2D locationCoordinate2D;
@property (nonatomic, strong) CLGeocoder *geocoder;

4、GelocationProvider.m文件添加block回调地址给控制器

@property (nonatomic, copy) void (^gelocationBlock) (NSString *string);

4、GelocationProvider.h文件代码

- (instancetype)init
{
    if (self = [super init]) {
        self.locationManage.delegate = self;
        self.locationCoordinate2D = CLLocationCoordinate2DMake(55, 34);
        
        if ([[UIDevice currentDevice].systemVersion intValue] <= 7) {
            NSLog(@"%.2f", [[UIDevice currentDevice].systemVersion doubleValue]);
        }
        else {
            NSLog(@"%.2f", [[UIDevice currentDevice].systemVersion doubleValue]);
            [self.locationManage requestWhenInUseAuthorization];
        }
        [self.locationManage startUpdatingLocation];
        
//需要等待进行locationManage走代理方法
        [self performSelector:@selector(getLocationInfo) withObject:nil afterDelay:1.0f];
        //反地理编码获取位置信息
    }
    return self;
}

- (void)getLocationInfo
{
    CLLocation *location = [[CLLocation alloc] initWithLatitude:self.locationCoordinate2D.latitude longitude:self.locationCoordinate2D.longitude];
    NSLog(@"latitude->%f, longitude->%f", self.locationCoordinate2D.latitude, self.locationCoordinate2D.longitude);
    [self.geocoder reverseGeocodeLocation:location completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
        if (error || placemarks.count == 0) {
            self.gelocationBlock(error.localizedDescription);
        }
        else {
            CLPlacemark *placemark = [placemarks firstObject];
            NSLog(@"-->%@", placemark.name);
            self.gelocationBlock(placemark.name);
        }
    }];
}

- (CLGeocoder *)geocoder
{
    if (!_geocoder) {
        _geocoder = [[CLGeocoder alloc] init];
    }
    return _geocoder;
}
- (CLLocationManager *)locationManage
{
    if (!_locationManage) {
        _locationManage = [[CLLocationManager alloc] init];
    }
    return _locationManage;
}
- (void)setLocationCoordinate2D:(CLLocationCoordinate2D)locationCoordinate2D
{
    _locationCoordinate2D = locationCoordinate2D;
}

#pragma mark --CLLocationManageDelegate
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"error->%@", error.localizedDescription);
    [self.locationManage stopUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations
{
    CLLocation *location = [locations lastObject];
    self.locationCoordinate2D = CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude);
    [self.locationManage stopUpdatingLocation];
}

6、在ViewController里面获取位置信息

GelocationProvider *gelocation = [[GelocationProvider alloc] init];
    gelocation.gelocationBlock = ^(NSString *string) {

    NSLog(@"位置信息->%@", string);
}
