Question

i am using custom checkbox buttons in my table view and want to save the selected cell’s data to a mutable array…. can anyone help me… Thanks

create a mutable array to store your selected data, lets call it ‘yourSeparatedData’ , set the tag of your checkbox in cellForRowAtIndexPath and set onCheck: method as target. the code will look like this:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *CellIdentifier = @"setMe";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyle………
    }
    checkBox = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    checkBox.frame = CGRectMake(customizeMe);
    if(yourSeparatedData && [yourSeparatedData indexOfObject:[yourTableViewDataSource objectAtIndex:indexPath.row]] != NSNotFound)
    {
        [checkBox setBackgroundImage:[UIImage imageNamed:@"check.png"] forState:UIControlStateNormal];
    }
       else {
        [checkBox setBackgroundImage:[UIImage imageNamed:@"unCheck.png"] forState:UIControlStateNormal];
        }
        [checkBox addTarget:self action:@selector(onCheck:) forControlEvents:UIControlEventTouchUpInside];
        [checkBox setTag:indexPath.row];

        [cell addSubview:checkBox];
        return cell;

}

-(void)onCheck:(id)sender {
     if(yourSeparatedData && [yourSeparatedData indexOfObject:[yourTableViewDataSource objectAtIndex:[sender tag]]] != NSNotFound)
       {
        [sender setBackgroundImage:[UIImage imageNamed:@"unCheck.png"] forState:UIControlStateNormal];
        [yourSeparatedData removeObject:[yourTableViewDataSource objectAtIndex:[sender tag]]];
       }
      else {
        [sender setBackgroundImage:[UIImage imageNamed:@"check.png"] forState:UIControlStateNormal];
        [yourSeparatedData addObject:[yourTableViewDataSource objectAtIndex:[sender tag]]];
      }
      [yourTableView reloadData];
 } 

this code is not tested, you are using checkbox so I assumed that you want to separate not just one data, at the end of the selection, you will have ‘yourSeparatedData’ with the objects picked from your tableView.
