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.
