How to measure Elevation using GPS technology for iPhone SDK?

There are few apps like Strava which records users movements using GPS. It also measures the elevation of the road on which they travelled.

I would like to know how can we measure elevation of the road using iPhone SDK?

Please let me know.

Use the Google Elevation API

Example here

Then use a JSON parser to retrieve the values

CoreLocation is what you want to use (although it is generally quite inaccurate I've found) first import the core location framework in the .h:

#import <CoreLocation/CoreLocation.h>

followed by in the .m:

- (void)locationUpdate:(CLLocation *)location {

altitudeLabel.text = [NSString stringWithFormat:@"Altitude - %f", [location altitude]];
}

This is given in height from sea level
