Question

I am currently trying to create a sort of tasktracker.. The following code works currently, but I need it to delete the row with the tag of the button.. In other words.

When button with tag:0 is pressed, delete row with tag:0

All my atempts have failed so I’m bringing it to the experts.

 - (void)buttonPressedAction:(id)sender
    {
        UIButton *button = (UIButton *)sender;
        NSInteger *row = button.tag;
        NSString *cleanedUp = [NSString stringWithFormat:@"%d", row];
            if(button.titleLabel.text == @"Unchecked"){
            [button setTitle:@"Checked" forState:UIControlStateNormal];
        }
        else{
            [button setTitle:@"Unchecked" forState:UIControlStateNormal];
        }
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:button.titleLabel.text 
                                                        message:cleanedUp
                                                       delegate:nil 
                                              cancelButtonTitle:@"OK"
                                              otherButtonTitles:nil];
        [alert show];

    }

UITableView has built-in capabilities to allow the deletion of rows. This may be better suited for what it sounds like you are trying to accomplish. Here is an example.

To use custom buttons you will need use beginUpdates and endUpdates to modify your table view animated.

NSInteger row = button.tag;
[tableView beginUpdates];
//make sure you remove the row from your datasource 
//as well or an exception will be raised
[self.datasource removeObjectAtIndex:row]
[deleteRowsAtIndexPaths:[NSIndexPath indexPathForRow:row inSection:0]
       withRowAnimation:UITableViewRowAnimationFade];

[tableView endUpdates];
