iOS >> ShareKit: Twitter & Facebook & Email Doesn't Receive my App Store Link

I'm implementing ShareKit in my app; I defined in the SHKConfig.h the following definitions:

#define SHKMyAppName @"MyAppName"

#define SHKMyAppURL @"http://itunes.apple.com/app/myAppName/idMyAppID"

When I share a link on Twitter or Facebook or Email, it doesn't publish my App Store App link. instead it publishes the following:

Email - No link at all:

Facebook - There is no link/image within the message like I would expect; instead, it only shows the message the user is writing - and the access to my app is from the unintuitive Facebook Get AppName link at the bottom of the feed:

Twitter - here it gives a strange notification saying I'm missing some sort of APIKEY that I couldn't find any definition on the ShareKit files to set:

and then on Twitter Feed:

Can anyone refer me to what I'm missing here?

Dun know if u found an answer but just for future reference, it is caused because of sharekit trying to shorten urls for tweets using bit.ly . just get an api key for bit.ly and put it in the config file , this will go away.
