POUIWebView Archiving - iPhone
text
Body
copied!<p>I am trying to archive my <code>UIWebView</code> object using <code>NSKeyedArchiver</code> and restore it later using <code>NSKeyedUnarchiver</code> in the same state. Archiving/Unarchiving works, but the <code>UIWebView</code> is blank when unarchived again (I archived it with a website loaded), but I need it to have the same website it did before I archived it. </p> <p>I've tried saving the <code>HTTPBody</code> of the <code>NSURLRequest</code> of the <code>UIWebView</code>, but that always returns <code>(null)</code>, so I think I am barking up the wrong tree there. (or I am fetching it wrong?)</p> <p>Here's what I have tried:</p> <pre><code>UIWebView*currentWebview = [[Controller sharedInstance] mainWebView]; NSData*webViewData = [NSKeyedArchiver archivedDataWithRootObject:currentWebview]; [sub setObject:webViewData forKey:@"Instance"]; //saves and decodes correctly, but that's a blank `UIWebView` even though I saved it with contents being loaded NSData*body = [[currentWebview request] HTTPBody]; //returns (null) always, but the webview is not null and has a valid request [sub setObject:body forKey:@"HTTP_Body"]; </code></pre> <p>What am I missing here? I need to retain the <code>UIWebView</code> as it was and load it again in the same state without having to open the URL at a later stage.</p> <p>And yes, I am aware of <code>document.documentElement.outerHTML</code> and <code>document.documentElement.innerHTML</code>, but that's <strong>not</strong> what I am looking for. I need to retain the whole website for later, not just the HTML code.</p> <p>Thanks!</p>
