How to scroll UITableView to specific position

Swift 4.2 version:

let indexPath:IndexPath = IndexPath(row: 0, section: 0)
self.tableView.scrollToRow(at: indexPath, at: .none, animated: true)

Enum: These are the available tableView scroll positions - here for reference. You don't need to include this section in your code.

public enum UITableViewScrollPosition : Int {

case None
case Top
case Middle
case Bottom
}

DidSelectRow:

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    let theCell:UITableViewCell? = tableView.cellForRowAtIndexPath(indexPath)

    if let theCell = theCell {
        var tableViewCenter:CGPoint = tableView.contentOffset
        tableViewCenter.y += tableView.frame.size.height/2

        tableView.contentOffset = CGPointMake(0, theCell.center.y-65)
        tableView.reloadData()
    }

}

[tableview scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO];

This will take your tableview to the first row.

it should work using - (void)scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated using it this way:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[yourTableView scrollToRowAtIndexPath:indexPath 
                     atScrollPosition:UITableViewScrollPositionTop 
                             animated:YES];

atScrollPosition could take any of these values:

typedef enum {
UITableViewScrollPositionNone,
UITableViewScrollPositionTop,
UITableViewScrollPositionMiddle,
UITableViewScrollPositionBottom
} UITableViewScrollPosition;

I hope this helps you
