You should not be using view controllers for the section headers. Remember that view controllers are designed around screenfuls of content - not to manage some subview of your table. Therefore you might be using a UITableViewController for the current screen, but for implementing your custom headers, all you will be doing is creating a custom subclass of UIView. As for the allocation problem, feel free to cache your custom header views if that makes sense for your application. Then when we ask for the header again, you can return the cached version. >> >> 2.

There's more than one way to skin this cat, but in my demo app, I simply assigned the section number as a property of the custom header view when I created it. That way, when it was tapped it could send a message back to the view controller that included its section index. >> >> I don't know if Luke is still on this list, and I also know this is might >> be too much to ask, but is there anyway we could take a look at the >> TableViewUpdates project, much like Francois Jouaux did with Padalicious? >> Maybe not all of it, just the part related to the headers? >> This project has been made into sample code on developer.apple.com. https://developer.apple.com/library/ios/samplecode/TableViewUpdates/ Luke_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
