Animation In UITableView

UITableView is used in various places in application , but some time we need to perform animation for that we have to add some code into it.

Follow some steps:

1: in viewWillAppear method write this method.

 override func viewWillAppear(_ animated: Bool) {
        listMenuArray = GlobalVariables.listMenuData;
        //self.listMenuTable.reloadData()
        self.navigationController?.isNavigationBarHidden = true
        animateTable()
    }

override func viewWillAppear(_ animated: Bool) {

listMenuArray = GlobalVariables.listMenuData;

//self.listMenuTable.reloadData()

self.navigationController?.isNavigationBarHidden = true

animateTable()

}

2: Now define this method in class:

func animateTable() {
       self.listMenuTable.reloadData()
        
        let cells = listMenuTable.visibleCells
        let tableHeight: CGFloat = listMenuTable.bounds.size.height
        
        for i in cells {
            let cell: UITableViewCell = i as UITableViewCell
            cell.transform = CGAffineTransform(translationX: 0, y: tableHeight)
        }
        
        var index = 0
        
        for a in cells {
            let cell: UITableViewCell = a as UITableViewCell
            UIView.animate(withDuration: 1.5, delay: 0.05 * Double(index), usingSpringWithDamping: 0.8, initialSpringVelocity: 0, animations: {
                cell.transform = CGAffineTransform(translationX: 0, y: 0);
            }, completion: nil)
            
            index += 1
        }
    }

func animateTable() {

self.listMenuTable.reloadData()

let cells = listMenuTable.visibleCells

let tableHeight: CGFloat = listMenuTable.bounds.size.height

for i in cells {

let cell: UITableViewCell = i as UITableViewCell

cell.transform = CGAffineTransform(translationX: 0, y: tableHeight)

}

var index = 0

for a in cells {

let cell: UITableViewCell = a as UITableViewCell

UIView.animate(withDuration: 1.5, delay: 0.05 * Double(index), usingSpringWithDamping: 0.8, initialSpringVelocity: 0, animations: {

cell.transform = CGAffineTransform(translationX: 0, y: 0);

}, completion: nil)

index += 1

}

3: Here listMenuTable is UITableView Instance.
