Personally I only have Pokemon Platinum but I'm pretty sure you go to the safari zone and this girl challenges you to catch a certain amount of Pokemon in the amount of time you get in the safari zone.I got it by catching every Pokemon I saw whether I liked it or not.I think this is the right app I'm talking about but just to make sure you should try it out just to make sure.

To access the friendship checker in pokemon white you need the C - Gear. After you obtain that, go to the IR options and go to the feeling check.

There is a special bell called the soothe bell that makes your Pokemon holding it like you more. Also I think there is a berry that does the same thing.
