I know its very late to answer this but hope this may help anyone.

you can create button like radio button using IBOutletCollection. create one IBOutletCollection property in our .h file.

@property (nonatomic, strong) IBOutletCollection(UIButton) NSArray *ButtonArray;

connect all button with this IBOutletCollection and make one IBAction method for all three button.

- (IBAction)btnTapped:(id)sender {
       for ( int i=0; i < [self.ButtonArray count]; i++) {
           [[self.ButtonArray objectAtIndex:i] setImage:[UIImage                         
            imageNamed:@"radio-off.png"]                 
            forState:UIControlStateNormal];
       }
     [sender setImage:[UIImage imageNamed:@"radio-on.png"]
      forState:UIControlStateNormal];
}

For options screens, especially where there are multiple radio groups, I like to use a grouped table view. Each group is a radio group and each cell a choice within the group. It is trivial to use the accessory view of a cell for a check mark indicating which option you want.

If only UIPickerView could be made just a little smaller or their gradients were a bit better suited to tiling two to a page...
