SnowCat.framework for iOS application is a framework for developing apps via creating some '.plist' files simply.
It is based on SlanissueToolkit.framework, copyright ©2015 Slanissue.com.

I suggest you controlling the UI via notifications, but not codes, the best habit is NOT writing any UI codes in your controllers.
You can do some calculating works in your codes (e.g.: a singleton instance),
and send out a notification to notice all guys that interest in the results.
As all SnowCat views & controllers can define a 'notifications' list and do some actions when these 'events' happen,
we can let the framework to do the UI works.
Meanwhile, you should send out a notification when some events happen in UI level (e.g.: a button clicked), so that guys interest in it will do their works when received this notification.
There are two ways to callback from the UI level:
- Notification
- CallFunc

// TODO: handle button1 clicked notification here.
