Type 1234 and it displays $12.34 but ...

But how? I thought I just needed to call "[self viewDidUnload]" but that doesn't seem to do it. Where is the "forceThisViewToUnloa...

Hi, I'm working on a pretty simple iPhone app at the moment. I have a UIWebView with a UIToolBar at the bottom of it with a button on it. I've built it all through code, although I did create an empty NIB as I am hoping to get Facebook Connect working with it eventually and have had problems when I don't set it up with this empty NIB in...
I have several html files which will be located in the documents directory at locations only known at runtime (may be within a varying tree hierarchy).

Works great, but Instruments is reporting two memory leaks. I'm using the code in a standard UIViewController, but that is inside a UINavigationContro...
This should be easy: When calling a didSelectRowAtIndexPath, I run a complex method, that downloads the contents of a URL, parses it, and put the result in the various properties. In the Simulator, and on a device in a WiFi situation, everything is just fine. However, on a device on a slower network, it just takes some time to process th...
