Extract image of UISegmentedControl on iPhone

Question

I am using UISegmentedControl (with only one segment) as a button. But problem with this is one cannot change font size in UISegmentedControl (possible in iOS-5+ but I am targeting lower versions devices). Is it possible to extract image of UISegmentedControl from app so that I can use custom UIButton with this image as background?

Any help will be appreciated.

for (UIImageView*imgView in segmentControl.subviews) {
    UIGraphicsBeginImageContext(imgView.frame.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    [segmentControl.layer renderInContext:context];
    UIImage *yourImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext(); 
}

and import QuartzCore.framework

thanks for the response. This solution works in simulator but fails on device with error message -[UISegment image]: unrecognized selector sent to instance 0x1b98c0. (in my case "thisbutton" is UIsegmentedControl with number of segments 1). DO you have any idea what might be the reason? – chatur Nov 14 '11 at 11:55
but this UIImageView is added by you or is standart ? :) – Igor Bidiniuc Nov 14 '11 at 13:57
