scrollToRowAtIndexPath with UITableView does not work

Heres Swift 3 version

let numberOfSections = self.tableView.numberOfSections
let numberOfRows = self.tableView.numberOfRows(inSection: numberOfSections-1)

if numberOfRows > 0 {
let indexPath = NSIndexPath.init(row: numberOfRows-1, section: numberOfSections-1)
self.tableView.scrollToRow(at: indexPath as IndexPath, at: UITableViewScrollPosition.bottom, animated: animated)
}

**SWIFT 3 VERSION of @Fox5150 answer, with an extension :**

extension UITableView {

func tableViewScrollToBottom(animated: Bool) {

DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(100)) {

let numberOfSections = self.numberOfSections
let numberOfRows = self.numberOfRows(inSection: numberOfSections-1)
if numberOfRows > 0 {
let indexPath = IndexPath(row: numberOfRows-1, section: (numberOfSections-1))
self.scrollToRow(at: indexPath, at: UITableViewScrollPosition.bottom, animated: animated)
}
}
}
}

**USAGE:**

self.tableView.tableViewScrollToBottom(animated: true)

Call scrollToLastPosition() method after loading the tableview like call from viewWillAppear( ) or after table view reload when some thing changed into tableview


func scrollToLastPosition() {
if !message.isEmpty {
let indexpath = NSIndexPath(forRow: message.count - 1 , inSection: 0)
self.tableView.scrollToRowAtIndexPath(indexpath, atScrollPosition: .Bottom, animated: true)
}
}

The better solution is to flip upside down the tableView so you can show new message just by
`-insertRowsAtIndexPaths:withRowAnimation:`

to do it you need first to flip your table by:

_tableView.transform = CGAffineTransformMakeScale (1,-1);

then don't forget to flip back your cells, best place to do it in -awakeFromNib by subclassing:

- (void)awakeFromNib {
[super awakeFromNib];
self.contentView.transform = CGAffineTransformMakeScale (1,-1);

//if you have accessoryView
self.accessoryView.transform = CGAffineTransformMakeScale (1,-1);
}

Try reloading first before calling scroll. Very weired but works for iOS8.

tableView.reloadData()
tableView.scrollToRowAtIndexPath(indexPath, atScrollPosition: UITableViewScrollPosition.Bottom, animated: animated)

I have the problem with a bigger index say even 15. Only indexes till 5-6 use to work. By making "animated: false" scrollToRowAtIndexPath() worked perfectly.

The solution at my problem is:

let numberOfSections = tableView.numberOfSections()
let numberOfRows = tableView.numberOfRowsInSection(numberOfSections-1)

if numberOfRows > 0 {
println(numberOfSections)
let indexPath = NSIndexPath(forRow: numberOfRows-1, inSection: (numberOfSections-1))
tableView.scrollToRowAtIndexPath(indexPath, atScrollPosition: UITableViewScrollPosition.Bottom, animated: animated)
}

If the keyboard is still visible you have to set the `UITableView`'s `contentInset` property to compensate for the keyboard height at the bottom of the screen. Otherwise your cell might be hidden behind the keyboard because the `UITableView` doesn't know that half of its content is hidden by it.

Or use a `UITableViewController` which handles that automatically.
