Getting the exact location of a UITableViewCell

Question

Given a UITableView, how can I find the location of a specific UITableViewCell? In other words, I want to get its frame relative to my iPhone screen, n

Answer 1

Swift-version of Tomasz and Jhaliya's answers in case anyone (else) struggles with this:

var cellRect = tableView.rectForRow(at: indexPath)
cellRect = cellRect.offsetBy(dx: -tableView.contentOffset.x, dy: -tableView.contentOffset.y)

Answer 2

If you really need to convert specifically to a point in the window, you could do this:

[yourAppDelegate.window convertPoint:[cell.contentView.center] fromView:[cell.contentView]];

I used the cells center coordinate, but you could use any point you want.

Vladimir is right, watch out for rows that are not visible (or that have been recycled).

try it in

didSelectRowAtIndexPath method

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];


        // get current location of selected cell

        CGRect rectInTableView = [tableView rectForRowAtIndexPath:indexPath];

        CGRect rectInSuperview = [tableView convertRect:rectInTableView toView:[tableView superview]];


         NSLog(@"Cell Y Is %f",rectInSuperview.origin.y);

        NSLog(@"Cell X Is %f",rectInSuperview.origin.x);

For future viewers, I was having trouble getting a reliable frame for cells in a UITableView. I was trying to display a UIAlertController in ActionSheet style on an iPad which needs a popover presentation. In the end this approach yielded the best results:

// 44 is the standard height for a cell in a UITableView
// path is the index path of the relevant row
// controller is the UIAlertController
CGRect frame = CGRectZero;
frame.origin.y = 44 * path.row;
frame.origin.x = table.frame.origin.x;
frame.size = CGSizeMake(table.frame.size.width, 44);
controller.popoverPresentationController.sourceRect = [tableView convertRect:frame toView:self.view];
controller.popoverPresentationController.sourceView = self.view;

Answer 5

Try the following(sending nil as a toView parameter means you want to convert you rect to window coordinates):

CGRect r = [cell convertRect:cell.frame toView:nil];

And remember that if particular row is not currently visible then there may not be UITableViewCell for it - so before using that code you may need to check if cell is valid (not nil for example)

You could also use the rectForRowAtIndexPath method to get the location of a UITableView by sending the indexPath for that.

- (CGRect)rectForRowAtIndexPath:(NSIndexPath *)indexPath

So use as below:

CGRect myRect = [tableView rectForRowAtIndexPath:indexPath];
