Simulated low memory warning not working
So I have a UIViewController with a webview in it. I tried pushing another viewcontroller into the nav controller and then simulate a memory warning and then go back. Now the view with the webview is purely blank. I tried adding a view and changing the background color to this code and it didn't add it after the memory warning. I tried calling setNeedsLayout and setNeedsDisplay and it didn't help either. It's as if the view is not there. So I double checked the view frame and it is:
<UIView: 0x8aebd70; frame = (0 0; 768 960); clipsToBounds = YES; autoresize = W+H; layer = <CALayer: 0x8ae2830>>
any idea why?
