我们如何在UIWebView中获取图像的URL？

Question

I just want to extract the url of an image that I touched from a UIWebView. How can we do that ? Thanks in advance!

I believe you'd have to use JavaScript to do this... or at least, that's one way of doing it. You can have a JavaScript function (say, URLofImageClicked ) that returns the URL of the clicked image. In Objective-C, you would make a call to that function using stringByEvaluatingJavaScriptFromString: . I would guess you would make that JavaScript call when UIWebView detects a click.

Hope this helps!
