How to set image to the UISegmentedControl in iPhone?

I am new to iPhone development. I have created UISegmentedControl having 2 segments. I want to display images for each segment instead of title. Here is my code

NSArray *itemArray = [NSArray arrayWithObjects: @"segment1", @"segment2", nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(5,100,300,40);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.selectedSegmentIndex = 1;
[self.view addSubview:segmentedControl];
[segmentedControl release]; 

But instead of displaying the title ,segment1 and segment2 it should be replaced with the images I have.

It is almost exactly what you had, just pass an array of UIImages instead of NSStrings.

NSArray *itemArray = [NSArray arrayWithObjects:
    [UIImage imageNamed:@"segment1.png"],
    [UIImage imageNamed:@"segment2.png"],
    nil];
