Question

有一个关于u tube的视频教程，展示了如何执行此操作。它包含一个UIwebview和工具栏按钮来保存内容。没有任何运气使这项工作。可以有人看看，看看他们可以做它工作。非常感谢提前。

-(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
