First thing: You should not be adding the UIButton's everytime the cell is loading. You should add them inside if (cell == nil) block.
Next thing: You should keep track of the selected radio button index (an int value) in a sepearate array (a NSMutableArray), and select the respective UIButton, outside the if (cell == nil) block.
I hope this tutorial will help you.
