如何将UIWebView的内容保存为图像(How do I save the contents of a UIWebView as an image)

我想将UIWebView的内容保存为图像。 我的代码只保存了屏幕上可见的网页内容。

- (IBAction)saveImage:(id)sender { UIGraphicsBeginImageContext(webCanvas.frame.size); [self.webCanvas.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage =UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIImageWriteToSavedPhotosAlbum(viewImage, nil,nil,nil); }

我想要它所以它会将整个网页保存在UIWebView包括屏幕UIWebView不到的网站部分。 这可能吗？

I want to save the content of UIWebView as an image. The code I have only saves the content of the webpage that is visible on the screen.

- (IBAction)saveImage:(id)sender { UIGraphicsBeginImageContext(webCanvas.frame.size); [self.webCanvas.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage =UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIImageWriteToSavedPhotosAlbum(viewImage, nil,nil,nil); }

I want it so it will save the whole webpage in the UIWebView including the part of the website that is not visible on screen. Is this possible?
