How can I get the indexPath of UIButton in a customized tableViewCell?

Question

Hi. I created a tableViewCell the include an image, two text labels and a uibutton. The button is allocated to an action method (e.g. viewButtonPused:sender).

I'm used to handle row selection with tableView:didSelectRowAtIndexPath: so I could tell which row was selected. But with the uibutton and its action method .... How can I tell?

Thanks in advance.

Answer 1

define one class variable int SelectedRow; inside didSelectRowAtIndexPath assign value to it like SelectedRow = indexPath.row;

use this SelectedRow variable in side your action method viewButtonPused:sender

Answer 2

Instead of adding the button as a subview of the cell set it to be cell.accessoryView. Then use tableView:accessoryButtonTappedForRowWithIndexPath: to do your stuff that should be done when a user taps this button.

Answer 3

when you set up each UITableViewCell in the cellForRowAtIndexPath: method assign a int to the button.tag propery that corrisponds to the row its on. That way when the viewButtonPused:sender is called you can do:

viewButtonPused:sender {

    UIButton *button = (UIButton *)sender;
    //check button.tag to see which row this button was.

}

If the button's target is the UIViewController/UITableViewController or any other object that maintains a reference to the UITableView instance, this will do nicely:

- (void)viewButtonPushed:(id)sender {
    UIButton *button = (UIButton *)sender;
    UITableViewCell *cell = button.superview; // adjust according to your UITableViewCell-subclass' view hierarchy
    NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
    // use your NSIndexPath here
}

Using this approach will let you avoid extra instance variables and will work fine in case you have multiple sections. You need to have a way to access the UITableView instance though.

Answer 5

Another way that I use now is to subclass UIButton and add a property of type NSIndexPath. On cellForRowAtIndexPath I assign the value of indexPath and its available at the action method.
