help on button.tag = indexPath.row - iphone

Question

I have this code on my cellForRowAtindexPath, with a custom cell and a button on the each cell.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"tblCellView";
TableCellView *cell = (TableCellView *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier];
Alarms *alarma = (Alarms *)[alarmsArray objectAtIndex: indexPath.row];
if (!cell) {
[[NSBundle mainBundle] loadNibNamed:#"TableCellView" owner:self options:nil];
cell = tblCell;
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(-7, 4, 30, 33)];
[button addTarget:self action:#selector(favButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[button setTag:1];
[cell.contentView addSubview:button];
[button release];
}
// Set up the cell.
[cell setLabelText: [alarma nombreAlarma]];
UIButton *button = (UIButton *)[cell viewWithTag:1];
button.tag = indexPath.row;
return cell;
}
My problem is that when I click on the button, I got random results, as soon as I move on the table and cells are reusing I got different indexes that are not equal to label tex for the cell in question.
-(IBAction)favButtonAction: (id)sender
{
UIButton *button = (UIButton *)sender;
Alarms *alarma = (Alarms *)[alarmsArray objectAtIndex: button.tag];
NSLog(#"labelText: %#",[alarma nombreAlarma]);
}
for example, the first cell always is ok but the last cell is equal to first objectAtIndex (maybe button.tag is equal to 0 when it must be 14?)

Answer 1

Ok I found a solution, is a different approach but it works :
[button addTarget:self action:#selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside];
and then on the button handler:
- (void)checkButtonTapped:(id)sender event:(id)event
{
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint: currentTouchPosition];
if (indexPath != nil)
{
...
}
}

Don't put tag value for button inside cell.
This is my button inside the content view of my cell. Note: button should be subview of Contentview.
[cell1.YourButton addTarget:self action:#selector(OnClickCategory:) forControlEvents:UIControlEventTouchUpInside];
Action for my button
- (void) OnClickCategory:(id) sender {
//NSIndexPath *indexPath =(NSIndexPath *)[sender tag];
UIView *senderButton = (UIView*) sender;
NSIndexPath *indexPath = [CategoryTable indexPathForCell: (UITableViewCell*)[[senderButton superview]superview]];
NSLog(#"%d",indexPath.row);
}
This works for me.
