iOS地圖定位系統語言為英文時，返回中文位置信息

需要在定位前后對系統語言進行轉換：

#pragma mark - CLLocationManagerDelegate

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{
    //獲取用戶位置
    CLLocation *location = [locations lastObject];
    //停止定位
    [_locationManager stopUpdatingLocation];
    
    //當定位成功后，如果horizontalAccuracy大於0，說明定位有效
    if (location.horizontalAccuracy < 0) {
        return;
    }
    //系統語言為英文時返回中文編碼
    NSMutableArray *defaultLanguages = [LRH_USERDEFAULT objectForKey:@"AppleLanguages"];
    [LRH_USERDEFAULT setObject:[NSArray arrayWithObjects:@"zh-hans",nil] forKey:@"AppleLanguages"];
    
    //逆地理編碼
    CLGeocoder *geocoder = [[CLGeocoder alloc]init];
    __weak typeof(self) weakSelf = self;
    [geocoder reverseGeocodeLocation:location completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
        NSString *cityName = @"";
        if (error) {
            LRHLog(@"沒有找到此經緯度的地理信息");
        } else {
            CLPlacemark *pmark = [placemarks firstObject];
            cityName = pmark.locality;
        }
        
        if (weakSelf.delegate && [weakSelf.delegate respondsToSelector:@selector(getLocationCityWith:withCityName:)]) {
            [weakSelf.delegate getLocationCityWith:self withCityName:cityName];
        }
        //還原系統語言
        [LRH_USERDEFAULT setObject:defaultLanguages forKey:@"AppleLanguages"];
    }];
}

 自己寫的一個定位管理類：
