Viewcontroller, Pageviewcontroller, pagecontentviewcontrollers
A viewcontroller adds a Pageviewcontroller
[Viewcontroller Addchildviewcontroller:_pageviewcontroller];
One pageviewcontroller add multiple pagecontentviewcontroller[Custom views] for subpage
[_pagecontentviewcontroller Setviewcontrollers:@[a,b,c]];
Tip: Start with a single set and then implement the Protocol method to get Befor,after's Contentviewcontroller

Pageviewcontroller is equivalent to a controller container, adding multiple contentviewcontroller, its own definition, and DataSource defined in the parent Viewcontroller
