-(IBAction)saveWeb:(id)sender 
{ 

    UIGraphicsBeginImageContext(webview.frame.size); 
    [self.webview.layer renderInContext:UIGraphicsGetCurrentContext()]; 
    UIImage *viewImage =UIGraphicsGetImageFromCurrentImageContext(); 
    UIGraphicsEndImageContext(); 
    UIImageWriteToSavedPhotosAlbum(viewImage, nil,nil,nil); 

} ////make sure u add the quartzcore frame work to get rid of the renderincontext problem flag
