Radio Button issue in Objective c - ios

Question

I have a table view in which I'm loading some data i'm trying to make radio button on that data, but when i select any cell it does not deselect other it is working as a check box . I'm confused where i'm doing mistake, My code is this,
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
radiobtn = [UIButton buttonWithType:UIButtonTypeCustom];
radiobtn.frame = CGRectMake(30, 60, 30, 30);
[radiobtn setImage:[UIImage imageNamed:#"circle.png"] forState:UIControlStateNormal];
[radiobtn setImage:[UIImage imageNamed:#"rights.png"] forState:UIControlStateSelected];
[radiobtn addTarget:self action:#selector(radiobtn:)
forControlEvents:UIControlEventTouchUpInside];
cell.accessoryView = radiobtn;
}
cell.textLabel.text = [dataArray objectAtIndex:indexPath.row];
cell.backgroundColor = [UIColor clearColor];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.font = [UIFont boldSystemFontOfSize:17];
UIView *selectionColor = [[UIView alloc] init];
selectionColor.backgroundColor = [UIColor colorWithRed:(0) green:(0) blue:(0) alpha:1];
cell.selectedBackgroundView = selectionColor;
cell.selectionStyle = UITableViewCellDragStateLifting;
return cell;
}
-(void)radiobtn:(UIButton *)sender
{
if([sender isSelected])
{
[sender setSelected:NO];
}
else
{
[sender setSelected:YES];
}
}
It is looking like this,

Try this.
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
UIButton *radiobtn = [UIButton buttonWithType:UIButtonTypeCustom];
radiobtn.frame = CGRectMake(30, 60, 30, 30);
radiobtn.userInteractionEnabled = NO;
[radiobtn setImage:[UIImage imageNamed:#"circle.png"] forState:UIControlStateNormal];
[radiobtn setImage:[UIImage imageNamed:#"rights.png"] forState:UIControlStateSelected];
// [radiobtn addTarget:self action:#selector(radiobtn:) forControlEvents:UIControlEventTouchUpInside];
cell.accessoryView = radiobtn;
}
cell.textLabel.text = [dataArray objectAtIndex:indexPath.row];
cell.backgroundColor = [UIColor clearColor];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.font = [UIFont boldSystemFontOfSize:17];
UIView *selectionColor = [[UIView alloc] init];
selectionColor.backgroundColor = [UIColor colorWithRed:(0) green:(0) blue:(0) alpha:1];
cell.selectedBackgroundView = selectionColor;
cell.selectionStyle = UITableViewCellDragStateLifting;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
UIButton *button = (UIButton *)cell.accessoryView;
button.selected = YES;
}
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
UIButton *button = (UIButton *)cell.accessoryView;
button.selected = NO;
}
