Reloading table view header or footer
I've been struggling with updating the content of a table view footer. I ended up creating a custom view that I hang on to, returning that from the delegate method, and then changing its content. But I'm looking at the Personal Hotspot UI in Settings, and I see that the section footer changes nicely when you enable and disable the hot spot. It resizes with animation, and the rest of the table doesn't change. How is this properly done? -- Rick ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Reloading table view header or footer
Have you tried any of these? reloadSections:withRowAnimation reloadRowsAtIndexPaths, perhaps? Or reloadSectionIndexTitles? Set an observer to the data record that is being used to populate that cell, then create a little method in your TV class that is triggered when that data value changes. Then within that method, issue the appropriate reload: [self.tableView reloadSections: mySectionIndexPath withRowAnimation: UITableViewRowAnimationNone] or [self.tableView reloadSectionIndexTitles]; or NSArray *mySectionIndex = [NSArray arrayWithObject[thatIndexPathForThisSection]] [ self.tableView reloadRowsAtIndexPath: mySectionIndex withRowAnimation: UITableViewRowAnimationNone]; Not sure if reloading a cell that is a section header will really do a refresh on it, but it looks like reloadSectionIndexTitles sure will.

Unfortunately, of those that cause a section to reload, it makes all the cells reload, too, which is something I want to avoid. -- Rick ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
