viewForFooterInSection not called for last section with reloadData

Question

I want to refresh the section footer(s) using reloadData, but right now all sections are updated except for the last one - viewForFooterInSection is not called, even if the footer is visible. Scrolling the view is the only way to call viewForFooterInSection for the last section. What could be the reason for this behavior? I'm using Autolayout.

EDIT: heightForFooterInSection is implemented to support different footer heights, but should maybe just return AutomaticDimension and the logic should go elsewhere?

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
        switch(tableView) {
        case self.firstTableView:
            let item = self.firstItems[section]
            let shouldShowFirstButton = myModel.hasActions(item)
            let shouldShowSecondButton = myModel.hasOtherActions(item)
           if shouldShowFirstButton && shouldShowSecondButton {
                return FirstFooterView.heightForTwoButtons()
            } else if shouldShowFirstButton ||shouldShowSecondButton{ 
               return FirstFooterView.heightForOneButton()
            } else {
               return OtherFooterView.height()
            }
        case self.secondTableView:
            return 0.0
        case self.thirdTableView:
            if self.state1 {
                return 70.0
            } else if selectedItem == nil {
                return 0.0
            }else{
                return 0.0
            }
        default:
            DDLogInfo("height 0 for section \(section)")
            return 1.0
        }

Can you please post relevant code here? – Aditya Srivastava Sep 08 '17 at 10:18 — Aditya Srivastava, Sep 08 '17 at 10:18

 UiView.setAnimationsEnabled(False)
 self.TableView.reloadSections(NSIndexSet(index: yoursection), 
 withRowAnimation: UITableViewRowAnimation.None)
 self.TableView.scrollToRowAtIndexPath(NSIndexPath(forRow: 0, inSection: 5), 
 atScrollPosition: UITableViewScrollPosition.Bottom, animated: false)
 UIView.setAnimationsEnabled(true)

Using this you can reload a particular section you want to reload. Hope it helps

Edit: If you want to scroll to particular position

  self.TableView.scrollRectToVisible(<#T##rect: CGRect##CGRect#>, animated: <#T##Bool#>)

Thanks, this seems to work! Just wondering if there is a way to scroll to the to exact position before the reload instead of a scroll position as .bottom? – Dan Sep 08 '17 at 13:28
Enum are there to set. But only other way for it work will be something like this self.TableView.scrollRectToVisible:CGRect(x:0, y:0, width:1, height:1) animated:false – cole Sep 08 '17 at 13:43
