How do I force a UIWebView to update when it's offscreen?

Question

I have a UIWebView that I'm setting to some text and displaying and then hiding, changing the text, and displaying again. The issue I'm running in to is that when I make the view visible again I see the old text for an instant. Is there a way to force the UIWebView to show the new text when it displays?

The code is ordered correctly and looks like this:

[back assignLabelText:[facts getCurrentFact].answer];
[self doAnimation:back.view andViewToHide:front.view flipRight:YES];

Answer 1

You should wait until at least the webview's webViewDidFinishLoad: is fired before revealing the webview. Even then there can be some lag, so I add an additional 0.1 second delay before revealing the view.

Answer 2

Call setNeedsDisplay on back's view

[back assignLabelText:[facts getCurrentFact].answer];
[[back view] setNeedsDisplay];
[self doAnimation:back.view andViewToHide:front.view flipRight:YES];
