UITextField subview of UITableViewCell, get indexPath of cell

Question

I have added a UITextField as a subview of a UITableViewCell. Then I have added a target and selector so that I can know

Answer 1

Call [UIView superview] on the field to get the cell that it's in, then call [UITableView indexPathForCell:] on the cell to get the index path.

UPDATE: on iOS 7 you need to call superview on that view too (extra layer of views); here's a category on UITableView that should work independent of iOS version:

@interface UITableView (MyCoolExtension) 

- (NSIndexPath *)indexPathForCellContainingView:(UIView *)view;

@end

@implementation UITableView (MyCoolExtension)

- (NSIndexPath *)indexPathForCellContainingView:(UIView *)view {
    while (view != nil) {
        if ([view isKindOfClass:[UITableViewCell class]]) {
            return [self indexPathForCell:(UITableViewCell *)view];
        } else {
            view = [view superview];
        }
    }

    return nil;
}

@end

Answer 2

I would like to share @Ertebolle code in swift -

extension UITableView
{
    func indexPathForCellContainingView(view1:UIView?)->NSIndexPath?
    {
        var view = view1;
        while view != nil {
            if (view?.isKindOfClass(UITableViewCell) == true)
            {
                return self.indexPathForCell(view as! UITableViewCell)!
            }
            else
            {
                view = view?.superview;
            }
        }
        return nil
    }
}

Answer 3

Instead of recursively trying to find the superview, there's a simpler solution:

Swift

func indexPathForCellContainingView(view: UIView, inTableView tableView:UITableView) -> NSIndexPath? {
    let viewCenterRelativeToTableview = tableView.convertPoint(CGPointMake(CGRectGetMidX(view.bounds), CGRectGetMidY(view.bounds)), fromView:view)
    return tableView.indexPathForRowAtPoint(viewCenterRelativeToTableview)
}

Objective-C

- (NSIndexPath *)indexPathForCellContainingView:(UIView *)view inTableView:(UITableView *)tableView {
    CGPoint viewCenterRelativeToTableview = [tableView convertPoint:CGPointMake(CGRectGetMidX(view.bounds), CGRectGetMidY(view.bounds)) fromView:view];
    NSIndexPath *cellIndexPath = [tableView indexPathForRowAtPoint:viewCenterRelativeToTableview];
    return cellIndexPath
}

I made this into a Gist for the Swift hearted

Answer 4

Swift 4/5

func indexPathForCellContainingView(view: UIView,
                                    inTableView tableView:UITableView) -> IndexPath? {
    let viewCenterRelativeToTableview =
        tableView.convert(CGPoint(x: view.bounds.midX, y: view.bounds.midY), to: view)
    return tableView.indexPathForRow(at: viewCenterRelativeToTableview)
}

Answer 5

Try this solution. It worked for me

   #pragma mark - Get textfield indexpath
- (NSIndexPath *)TextFieldIndexpath:(UITextField *)textField
{
    CGPoint origin = textField.frame.origin;
    CGPoint point = [textField.superview convertPoint:origin toView:self.TblView];

    NSIndexPath * indexPath = [self.TblView indexPathForRowAtPoint:point];
    NSLog(@"Indexpath = %@", indexPath);
    return indexPath;
}
