Question

I subclassed UITableViewCell and added a round rec button using IB.

Normally, the event will be handled on the class of my custom UITableViewCell.

But how do handle the event that the button is clicked on the viewController which has a UITableView that uses this UITableViewCell?

Answer 1

When creating the custom cell, make sure you are adding the view controller as the button action’s target. So in your view controller’s (assuming it is the datasource for the table view):

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // All your standard identifier & dequeueing stuff here
    if (cell == nil) 
    {
        // We are creating a new cell, let's setup up its button's target & action 
        cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
        [cell.yourButton addTarget:self action:@selector(yourAction:) forControlEvents:UIControlEventTouchUpInside];
    }
    return cell;
}
