Send UIButton touch event to didSelectRowAtIndexPath

Question

I have a UIButton added to a UITableViewCell

In order to reduce code redundancy, I'd like to touch event of UIButton to fall through the cell - so it ends up in:

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

Can you tell me how?

Answer 1

In your button's action method, you can determine the index path of the row from the table view and pass that to the delegate method:

- (IBAction)buttonClicked:(UIButton *)button
{
    CGPoint point = [button center];
    UITableView *table = [self tableView];
    NSIndexPath *indexPath = [table indexPathForRowAtPoint:point];
    [[table delegate] tableView:table didSelectRowAtIndexPath:indexPath];
}

Answer 2

That's a bad idea. Instead, you should call the same function from didSelectRowAtIndexPath: & the button's action method & place your common code in that function. Something like-

- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//fetch the cell corresponding to this index path
MyCustomCell* cell = (MyCustomCell*)[self cellForRowAtIndexPath:indexPath] ;
[cell foo] ; 


}

-(void) buttonClicked:(id)sender //In your custom cell class
{
    [self foo];
}

HTH,
