644 CHAPTER 18: Where Am I? Finding Your Way with Core Location newLocation.altitude]; altitudeLabel.text = altitudeString; NSString *verticalAccuracyString = [NSString stringWithFormat:@"%gm", newLocation.verticalAccuracy]; verticalAccuracyLabel.text = verticalAccuracyString; NOTE: Both the longitude and latitude are displayed in formatting strings containing the cryptic- looking \u00B0. This represents the Unicode representation of the degree symbol (°). It's never a good idea to put anything other than ASCII characters directly in a source code file, but including the hex value in a string is just fine, and that's what we've done here. Determining Distance Traveled Finally, we determine the distance between the current location and the location stored in startingPoint and display the distance. While this application runs, if the user moves far enough for the location manager to detect the change, the Distance Traveled: field will be continually updated with the distance away from where the user was when the application was started. CLLocationDistance distance = [newLocation distanceFromLocation:startingPoint]; NSString *distanceString = [NSString stringWithFormat:@"%gm", distance]; distanceTraveledLabel.text = distanceString;
