iOS简单获取当前地理坐标

self.locatiOnManager= [[CLLocationManager alloc] init];
    // 设置定位精度，十米，百米，最好
    self.locationManager.desiredAccuracy=kCLLocationAccuracyBest;
    //每隔多少米定位一次（这里的设置为任何的移动）
    self.locationManager.distanceFilter = kCLDistanceFilterNone;
    self.locationManager.delegate = self; //代理设置
    
    // 开始时时定位
    if ([CLLocationManager locationServicesEnabled])
    {
        // 开启位置更新需要与服务器进行轮询所以会比较耗电，在不需要时用stopUpdatingLocation方法关闭;
        [self.locationManager startUpdatingLocation];
    }else
    {
        NSLog(@"请开启定位功能");
    }

//开启定位后会先调用此方法，判断有没有权限
-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
    if ([CLLocationManager authorizationStatus]==kCLAuthorizationStatusNotDetermined)
    {
        //没有权限，调用方法开启权限
        [self.locationManager requestAlwaysAuthorization];
        
    }else if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusAuthorizedWhenInUse)
    {
        [self.locationManager startUpdatingLocation];
    }
}

//成功获取到经纬度
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    // 获取经纬度
    NSLog(@"纬度:%f",newLocation.coordinate.latitude);
    NSLog(@"经度:%f",newLocation.coordinate.longitude);
    // 停止位置更新
    [manager stopUpdatingLocation];
}

// 定位失败错误信息
-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"error");
