保存UIwebview的內容到照片庫

Question

有一個關於U管的視頻教程，顯示如何執行此操作。它包含一個UIwebview和工具欄按鈕來保存內容。沒有任何運氣使這項工作。有人有一個看看，看看他們可以使它工作。多提前感謝。

-(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
