have you actually tried it? I'm currently working on a project with several 3D transforms, and when I try to programmatically make this screenshot it works just fine :) Here is the code I use:

-(UIImage *)getScreenshot
{
    CGFloat scale = 1.0;
    if([[UIScreen mainScreen]respondsToSelector:@selector(scale)])
    {        
        CGFloat tmp = [[UIScreen mainScreen]scale];
        if (tmp > 1.5)
        {
            scale = 2.0;    
        }
    }      
    if(scale > 1.5)
    {
        UIGraphicsBeginImageContextWithOptions(self.frame.size, NO, scale);
    } 
    else
    {
        UIGraphicsBeginImageContext(self.frame.size);
    }    
    //SELF HERE IS A UIVIEW
    [self.layer renderInContext:UIGraphicsGetCurrentContext()];    
    UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return screenshot;
}
