The following simple way to create radio button in your iOS app follow two steps.

Step1- Put this code in your in viewDidLoad or any other desired method

 [_mrRadio setSelected:YES];
        [_mrRadio setTag:1];
        [_msRadio setTag:1];
        [_mrRadio setBackgroundImage:[UIImage imageNamed:@"radiodselect_white.png"] forState:UIControlStateNormal];
        [_mrRadio setBackgroundImage:[UIImage imageNamed:@"radioselect_white.png"] forState:UIControlStateSelected];
        [_mrRadio addTarget:self action:@selector(radioButtonSelected:) forControlEvents:UIControlEventTouchUpInside];

        [_msRadio setBackgroundImage:[UIImage imageNamed:@"radiodselect_white.png"] forState:UIControlStateNormal];
        [_msRadio setBackgroundImage:[UIImage imageNamed:@"radioselect_white.png"] forState:UIControlStateSelected];
        [_msRadio addTarget:self action:@selector(radioButtonSelected:) forControlEvents:UIControlEventTouchUpInside];

Step2- Put following IBAction method in your class

-(void)radioButtonSelected:(id)sender
{
    switch ([sender tag ]) {
        case 1:
            if ([_mrRadio isSelected]==YES) {
              //  [_mrRadio setSelected:NO];
               // [_msRadio setSelected:YES];
               genderType = @"1";
            }
            else
            {
                [_mrRadio setSelected:YES];
                [_msRadio setSelected:NO];
                genderType = @"1";
            }
            break;
        case 2:
            if ([_msRadio isSelected]==YES) {
               // [_msRadio setSelected:NO];
               // [_mrRadio setSelected:YES];
                genderType = @"2";
            }
            else
            {
                [_msRadio setSelected:YES];
                [_mrRadio setSelected:NO];
                 genderType = @"2";
            }
            break;
        default:
            break;
    }
}
