以编程方式拍摄视图/ WebView的快照 [英] Take snapshot of view / WebView programmatically

问题描述

我想拍摄一个视图（WebView）的快照，或者如果不可能的话，整个屏幕，我可以将其保存到用户的照片库中。我想知道这是否可行。

I want to take a snapshot of a view (WebView) or, if that is not possible, the whole screen, so I can save it into the user's photo gallery. I was wondering if this is possible.

推荐答案

要获取图像，您需要使用：

To get the image, you'll want to use:

UIGraphicsBeginImageContext(self.bounds.size);

[theView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

然后，要保存到照片库：

Then, to save to the Photos Library:

UIImageWriteToSavedPhotosAlbum(viewImage,nil,NULL,NULL);
