You can use KMLViewer Sample code which has been provided by Apple which you will get in the following link, http://developer.apple.com/library/ios/#samplecode/KMLViewer/Introduction/Intro.html

In this, path has been drawn with the help of KML file.

You can get the coordinates between the Source and destination by using following URL, https://maps.google.com/maps?saddr=SOURCE_COORDINATES&daddr=DESTINATION_COORDINATES&output=kml

and you will have to parse above URLSTRING with following code,

parseKMLAtURL:URLSTRING
