Start UITableView scrolled to bottom

Question

How do I start a UITableView scrolled to the last cell?

• not animated
• not after view appeared
• not after table view is even added as a subview

just have a plain UITableView(frame: CGRectZero, style: UITableViewStyle.Plain) that when presented on screen, will start scrolled all the way to the bottom.

I've tried:

// 1
reloadData()
scrollToRowAtIndexPath(
    NSIndexPath(forItem: dataArray.count-1, inSection: 0),
    atScrollPosition: .Top, animated: false
)

// 2
reloadData()
var contentOffset = self.contentOffset
contentOffset.y = CGFloat.max
setContentOffset(contentOffset, animated: false)

on the tableView's init method (in my subclass)

I've also tried the classic CGAffineTransformMakeScale(1,-1) hack, but that makes my cells stick to the bottom and I want them stuck the the top (but scrolled to the bottom). (that is only relevant if I have few cells, when they don't fill the entire UITableView space)

EDIT: another detail, I'm using dynamic cells UITableViewAutomaticDimension.

This will scroll to bottom without any glitch, but if you use Tableview scroll-to-row property then there will be glitch.

For Swift 3 use

self.TableView.reloadData() // To populate your tableview first
//Since we have to wait until the table is reload
 DispatchQueue.main.async {
 let bottomOffset = CGPoint(x: 0, y: self.TableView.contentSize.height - self.TableView.frame.size.height)
 self.TableView.setContentOffset(bottomOffset, animated: false)
 }

For Objective C use

[YourTableView reloadData]; // To populate your tableview first

[YourTableView setContentOffset:CGPointMake(0, YourTableView.contentSize.height - YourTableView.frame.size.height)];
