Answer 1

The simplest solution is to set that topView as tableHeaderView .

self.tableView.tableHeaderView = topView

Now when you scroll the tableView topView will goes up with it. Also no need to implement scrollViewDidScroll now.

Answer 2

Select your tableview in your Controller of Storyboard

1. Select your TableView
2. Go to Attributes Inspector on the right panel of Utilities
3. Set Style to Grouped
