Question

I create tow or more custom cell

each cell has a switch inside

How can I know which switch in the row I click

ex.I click the switch in row 3,than It will return indexPath.row = 3

and also the switch status is on or off ?

which void I should put in ?

I know there is a way can get indexpath return by:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

But I don’t want to touch the row,just the switch …

Oh I do some research but it just be a little different

How can keep track of the index path of a button in a tableview cell?

any ideas ?

I wish I can post my screen shot,but not I am a new user
the system doesn’t allow me to do this

When you create the switch, set up a target and action for it:

[mySwitch addTarget:self action:@selector(switchToggled:) forControlEvents:UIControlEventValueChanged];

Here, the target self is your UITableViewController, in which you’ll need to implement the method (void) switchToggled:(id)sender to handle the control event. The switch will automatically send itself to the switchToggled method as the sender when it is toggled. Like this (modified from the UIButton example you linked):

- (void)switchToggled:(id)sender {
    UISwitch *theSwitch = (UISwitch *)sender;
    UITableViewCell *cell = (UITableViewCell *)theSwitch.superview;
    UITableView *tableView = (UITableView *)cell.superview;
    NSIndexPath *indexPath = [tableView indexPathForCell:cell];

    if(theSwitch.on) {
      // switch turned on
    }
    else {
      // switch turned off
    }
}
