i am doing feedback form using UITableview in that using custom checkbox for selection.In a UITableviewcell i placed four static buttons for options like,**Very 
Good**,**Good**,**Average**,**Below Average**.

What i want is,i want to select only one button checked in a row, if i select another button checked automatically previous selected button should be unchecked.

Example: In same row suppose if i select **Very Good** first again i selected **Average** , previous selected **Very Good** should be unchecked.

Check My code Below for reference:

This is in cellforrowatindexpath

```
[cell.R1_BTN setImage:[UIImage imageNamed:@"Touch_G.png"] forState:UIControlStateNormal];
[cell.R1_BTN addTarget:self action:@selector(BtnClicked:) forControlEvents:UIControlEventTouchUpInside]; 
cell.R1_BTN.tag=1;

```
