UIKIt Channel and User Filters

Thanks, I read the guide you posted and it is the concept I am attempting to do in iOS, Android UIKit. I am looking at iOS currently and do not see how I can modify the search query in the SBUChannelListViewController.

There is an instance variable, channelListQuery, that I would like to be able to override as the default query by adding 1 additional criteria which is the custom type. So far I do not see an interface for being able to modify the query. Also I would like this filter to always be applied when I use that viewcontroller.
