{
if(CabinInfoPopupSegmentControl.selectedSegmentIndex == 0)
{

    if(!cabinInfoDetailsViewObj)
    {
        cabinInfoDetailsViewObj = [[CabinInfoDetailsView alloc]initWithFrame:CGRectMake(232, 188, 617,412)];
    }
    [CabinInfoPopupSegmentControl setImage:[UIImage imageNamed:@"16.4_WhiteButton.png"] forSegmentAtIndex:0];
    [CabinInfoPopupSegmentControl setImage:[UIImage imageNamed:@"16.4_GreyButton.png"] forSegmentAtIndex:1];

if(CabinInfoPopupSegmentControl.selectedSegmentIndex == 1)
{
    if(!cabinInfoDeckPlansViewObj)
    {
        cabinInfoDeckPlansViewObj = [[CabinInfoDeckPlansView alloc]initWithFrame:CGRectMake(232, 188, 617,412)];

in my application,used this code :

//Give .h file UISegmentedControl  *seg;


- void)viewDidLoad
{

 seg        = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Notification", @"Messages", nil]];
seg.tag                         = 1;
seg.segmentedControlStyle       = UISegmentedControlStyleBar;
seg.frame                       = CGRectMake(1, 0, 318, 45);
[seg addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
seg.tintColor                   = [UIColor whiteColor];
seg.selectedSegmentIndex        = 0;
seg.backgroundColor=[UIColor clearColor];
[seg setDividerImage:[UIImage imageNamed:@""] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[seg setImage:[UIImage imageNamed:@"notificationselected.png"] forSegmentAtIndex:0];
[seg setImage:[UIImage imageNamed:@"message.png"] forSegmentAtIndex:1];
[self.view addSubview:seg];

}

pragma mark - UISegmentedControl
- (IBAction)segmentAction:(id)sender
{
UISegmentedControl *segControll = (UISegmentedControl *)sender;
if (segControll.selectedSegmentIndex==0)
{
    [segControll setImage:[UIImage imageNamed:@"notificationselected.png"] forSegmentAtIndex:0];
    [segControll setImage:[UIImage imageNamed:@"message.png"] forSegmentAtIndex:1];

 //right code for select the segmentcontroll.index=0
}
else if (segControll.selectedSegmentIndex==1)
{
    [segControll setImage:[UIImage imageNamed:@"notification.png"] forSegmentAtIndex:0];
    [segControll setImage:[UIImage imageNamed:@"messageselected.png"] forSegmentAtIndex:1];

    //right code for select the segmentcontroll.index=1
  }
}

i hope it will help you.
