- (void)followMe;
method in SHKTwitter
class can be used only when your app uses xAuth as authentification method with pre iOS5 Twitter. Some info about xAuth authentication method is in DefaultSHKConfigurator.m
file.
The method by default not used for OAuth authentication method, which is what you do most probably use.
edit:
It might work also with OAuth, if you specify twitterUsername to follow in SHKConfigurator.m.
The method can be called after user authenticates, most conveniently during send - so to be able to call it you should subclass SHKTwitter and override send method to call also [self followMe];
I have not tried it myself, it is just an idea.
Maybe it would be worth implementing it directly in ShareKit also for OAuth using sharer specific instruction...
