Question

I have a custom cell for a UITableView. The cell has a button in it called ShowData. I add a selector for that button:

[cell.ShowData addTarget:self action:@selector(ShowData:) forControlEvents:UIControlEventsTouchUpInside];

in My ShowData: method, I’d like some of the info that I used in displaying the cell. How can I pass information in this way? Thanks.

Answer 1

Your showData: will receive the button itself as its sender argument. You can walk up the button’s superviews until you find your custom cell and then access any properties you’ve added to the cell.

- (IBAction)showData:(id)sender
{
    while (sender && ![sender isKindOfClass:[MyCustomTableViewCell class]])
        sender = [sender superview];
    if (!sender) {
        // error
    }

    MyCustomTableViewCell *cell = sender;
    // do stuff using cell
}
