Ios 如何将经度和纬度转换为点

Ios 如何将经度和纬度转换为点,ios,android-mapview,Ios,Android Mapview,我正在努力获取当前位置的经度和纬度,我正在使用代码 locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.distanceFilter = kCLDistanceFilterNone; // whenever we move locationManager.desiredAccuracy = kCLLocationAccura

我正在努力获取当前位置的经度和纬度,我正在使用代码

locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLDistanceFilterNone; // whenever we move
    locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; // 100 m
    [locationManager startUpdatingLocation];

    - (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation{
    int degrees = newLocation.coordinate.latitude;
    double decimal = fabs(newLocation.coordinate.latitude - degrees);
    int minutes = decimal * 60;
    double seconds = decimal * 3600 - minutes * 60;
    lat = [NSString stringWithFormat:@"%d° %d' %1.4f\"",
                     degrees, minutes, seconds];
    NSLog(@" Current Latitude : %@",lat);

    degrees = newLocation.coordinate.longitude;
    decimal = fabs(newLocation.coordinate.longitude - degrees);
    minutes = decimal * 60;
    seconds = decimal * 3600 - minutes * 60;
  //  longt = [NSString stringWithFormat:@"%d° %d' %1.4f\"",
                //       degrees, minutes, seconds];

    longt = [NSString stringWithFormat:@"%d° %d' %1.4f\"",
             degrees, minutes, seconds];
    NSLog(@" Current Longitude : %@",longt);

}
以及获得:

当前纬度:37°47'9.0024“ 当前经度:-122°24'23.1012“


但是我想要像13.233233这样的纬度和经度(以点为单位)。那么我如何将其转换为经度和纬度?请提供帮助。

为什么要使用此折旧方法在iOS 7中使用此方法获取位置。使用这种方法

 -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

    {
   // location_updated = [locations lastObject];    
   // NSLog(@"updated coordinate are %@",location_updated);

    float currentLocationLati = [[locations objectAtIndex:0] coordinate].latitude;
        float currentLocationLong = [[locations objectAtIndex:0] coordinate].longitude;

    }

通过这种方法,您将发现更新纬度和经度只需使用它们,不要从下面的答案中将它们转换为度


其中R是地球的近似半径(例如6371KM)。

在newLocation.coordinate.latitude和newLocation.coordinate.longitude中,你有你想要的值,只是不转换它们。

你所说的“点”到底是什么意思?在笛卡尔坐标系中。在什么坐标系的笛卡尔坐标系中?UIView还是MKMapView?目的是什么?如果您只想以十进制格式显示它们,请执行NSLog(@“lat,long=%f,%f”,newLocation.coordinate.latitude,newLocation.coordinate.longitude)。另外,这不是一个“android地图视图”。这是一个更新位置的数组,我更新我的答案,你可以从那里得到浮动的纬度和经度
x = R * cos(lat) * cos(lon)
y = R * cos(lat) * sin(lon)
z = R *sin(lat)
