In your custom UIActivity subclass you have to simply override one method:

+ (UIActivityCategory)activityCategory
{
   return UIActivityCategoryShare;
}

There are to possible categories: action and share.
It's important, this is class method, not instance. Also, it's iOS 7 specific - all action activities are placed in bottom line (if any), then above the share activities and then above AirDrop. So, if you want to get rid of bottom line for example, simply exclude all action activities. If you want to put something in share/action line - override activityCategory. default is UIActivityCategoryShare;
