TAUniversityChildVC is a ASViewController which node is ASTableNode. But my first TAUniversityChildVC.tableNode just like this:enter image description here, and when I scroll scrollNode, the second TAUniversityChildVC.tableNode is added to scrollNode，and it's frame is normal

TAUniversityNode is TAUniversityVC's node like this:

class TAUniversityVC: ASViewController 

 var categorys = [String]()

 var universityNode: TAUniversityNode 
 return node as! TAUniversityNode
 

 init() 
 super.init(node: TAUniversityNode())
 automaticallyAdjustsScrollViewInsets = false
 

 required init?(coder aDecoder: NSCoder) 
 fatalError("init(coder:) has not been implemented")
 


extension TAUniversityVC 

 override func viewDidLoad() 
 super.viewDidLoad()
 setupInterwork()
 

 func setupInterwork() 
 categorys.append(contentsOf: ["全部", "微课程", "文学历史", "健康生活", "文艺兴趣", "中医养生", "拳操健身", "中西烹饪"])
 universityNode.categorys = categorys
