Scroll All the Way Down to the Bottom of Uitableview

Scroll all the way down to the bottom of UITableView

If your requirement is to scroll to the last cell of tableView you can use setContentOffset like this so that you can scroll to the last cell of tableView.

Put this in the reloadData() function:

func reloadData(){
    chatroomTableView.reloadData()
    dispatch_async(dispatch_get_main_queue(), { () -> Void in
        let scrollPoint = CGPoint(x: 0, y: self.chatroomTableView.contentSize.height - self.chatroomTableView.frame.size.height)
        self.chatroomTableView.setContentOffset(scrollPoint, animated: true)
    })
}

Add this to your UITableViewDelegate :

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
        let lastRowIndex = tableView.numberOfRowsInSection(0)
        if indexPath.row == lastRowIndex - 1 {
            tableView.scrollToBottom(true)
        }
    }

Add this to the bottom of your .swift file:

extension UITableView {
    func scrollToBottom(animated: Bool = true) {
        let sections = self.numberOfSections
        let rows = self.numberOfRowsInSection(sections - 1)
        if (rows > 0){
            self.scrollToRowAtIndexPath(NSIndexPath(forRow: rows - 1, inSection: sections - 1), atScrollPosition: .Bottom, animated: true)
        }
    }
}

Auto scroll to bottom of UITableView

let indexPath = IndexPath(item: noOfRows, section: 0)
yourTableView.scrollToRow(at: indexPath, at: UITableView.ScrollPosition.bottom, animated: true)

How to scroll to the bottom of a UITableView on the iPhone before the view appears

I believe that calling

 tableView.setContentOffset(CGPoint(x: 0, y: CGFloat.greatestFiniteMagnitude), animated: false)

will do what you want.

UITableView scroll to bottom

Scrolling to tableViewCell?

//for instance, you have 15 cells
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:14 inSection:0];
[self.tableView scrollToRowAtIndexPath:indexPath
                      atScrollPosition:UITableViewScrollPositionTop
                              animated:YES];

iOS UITableView Scroll to bottom of section

You can try with this code:

int yourSection = 2;
int lastRow = [tableView numberOfRowsInSection:yourSection] - 1;
[tableView scrollToRowAtIndexPath:[NSIndexPath lastRow inSection:yourSection] atScrollPosition:UITableViewScrollPositionBottom animated:YES];

You get the numbers of rows in your section, then scroll to that indexPath.

UITableView not scrolling to the bottom

Not being able to scroll to the bottom of the tableview is usually a symptom of its height being too large. (i.e. it's cut off at the bottom)

Don't compute the height you need and put those numbers in your code. Just find out what it should be from the view hierarchy. For example, you might compute the height of your table view with CGRectGetHeight(self.view.bounds) - CGRectGetMaxY(self.iAdView), and the view's y origin with CGRectGetMaxY(self.iAdView) assuming that the iAd view and your table view are both subviews of self.view. Or, even better, just use autoresize masks or autolayout to keep the table view the right size.

Tableview won't fully scroll to the bottom

the is because of tabBar it is hide the table view so you can add this code to your ViewController

let adjustForTabbarInsets: UIEdgeInsets = UIEdgeInsets(0, 0, self.tabBarController!.tabBar.frame.height, 0)
self.yourTableView.contentInset = adjustForTabbarInsets
self.yourTableView.scrollIndicatorInsets = adjustForTabbarInsets

Detect when UITableView has scrolled to the bottom

Swift 3

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    if indexPath.row + 1 == yourArray.count {
        print("do something")
    }
}
