在iPhone上提取UISegmentedControl的图像

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.

Answer 1

尝试UIKit-Artwork-Extractor（在github.com上查找）

Answer 2

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
