I can think of two solutions:

To use Apple's CLPlacemark and CLGeoCoder as this answer Get current city and country from CLGeocoder?
To use the Google Geocoding API https://developers.google.com/maps/documentation/geocoding/?csw=1

Thaks for your reply but I want to display any alert if user selectes different countries as source and destinations ,so what should i do to compare – Feb 02 '15 at 06:44
Check if the source and destination have the same country code or name that will insure that both points are in the same country. Therefore you can route else alert the user. – Ashraf Tawfeeq Feb 02 '15 at 06:58
