Question

I am currently doing this tutorial to get the GPS coordinates of my present location. I need to know what these values means?

The first 2 values are the geo-coordinates, and i don’t know what the other attributes are ?

Answer 1

From Apple’s iOS Developer Library what you are seeing as a result of the description selector being sent to your CLLocation object (which represents your current location and other location-related info):

A string of the form <<latitude>, <longitude>> +/- <accuracy>m (speed
<speed> kph / heading <heading>) @ <date-time>, where <latitude>,
<longitude>, <accuracy>, <speed>, and <heading> are formatted floating
point numbers and <date-time> is a formatted date string that includes
date, time, and time zone information.

What you probably want to do now is extract info from your CLLocation object by accessing its various properties (e.g. CLLocation.altitude will return the altitude only). Generally, aside from debugging purposes to the console, you would not want to print or display to the user the result of [CLLocation description] which is what you have there!
