I am using a subclass of UIViewController to manage a TableView page. When I get some XML data I want to force the table to repaint. I call reloadData on the TableView, but get not response. If I click on the table it repaints. What am I doing wrong? numberOfRowsInSection etc are not being called by the processing of reloadData.

Thanks,
Gerry

Are you calling reloadData from the main thread? That's the only one allowed to update the UI.

No, I'm not. How do I make the call on the main thread from my thread that has responded to the update?

Thanks,

Search the Developer Documentation for "mainthread".

Thanks,

I found the performSelectorOnMainThread method which does what is needed.

Great. That's what I was hoping you'd say!
