在iOS的UITableviewcell中选择单选按钮

Question

Am display list of names in UITableview and I'm trying to select any one of the names by using radio button. The problem I face is I can't select the specific row of the cell, either all the rows are selected or deselected.

Code for displaying radio button in cell:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UIButton *report_but;
int flag;

static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == Nil) 
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

}
 cell.textLabel.text = [user_name objectAtIndex:indexPath.row];

report_but = [UIButton buttonWithType:UIButtonTypeRoundedRect];
report_but.frame = CGRectMake(260,18,20,20);
[report_but setTitle:@"" forState:UIControlStateNormal];

if (flag == 0) {
    [report_but setBackgroundImage:[UIImage imageNamed:@"radio_blank.png"] forState:UIControlStateNormal];
}
else
[report_but setBackgroundImage:[UIImage imageNamed:@"radio.png"] forState:UIControlStateNormal];

[report_but addTarget:self action:@selector(radio_button:)forControlEvents:UIControlEventTouchUpInside];

[cell.contentView addSubview:report_but];
return cell;
}

- (void)radio_button:(id)button
{

NSLog(@"radio button clicked");
NSLog(@"button tag %@",button);
if (flag == 0) {
    flag = 1;
}
else
    flag = 0;

[table_list reloadData];

}

While row 1 is selected

And I can't use didselectrowatindexpath method for this single row selection, since selecting the row should not select the radio button.

Can any one help me to select the only one row of this tableviewcell.

Try this,

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    UIButton *report_but;
    if (cell == Nil) 
    {
         cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
         UIButton *report_but = [UIButton buttonWithType:UIButtonTypeRoundedRect];
         report_but.frame = CGRectMake(260,18,20,20);
         [report_but setTitle:@"" forState:UIControlStateNormal];
         report_but.tag = 8888;
         [cell.contentView addSubview:report_but];
    } 

    report_but = (UIButton *)[cell.contentView viewWithTag:8888];
    if (selectedIndexPath && selectedIndexPath.row == indexPath.row) {

    } else {

    }

}

and in radio_button:

- (void)radio_button:(id)button
{
     CGPoint pointInTable = [button convertPoint:button.bounds.origin toView:self.tableView];    

     selectedIndexPath = [self.tableView indexPathForRowAtPoint:pointInTable];
     [table_list reloadData];
}
