ViewWillAppear not called in UITableViewController?

Question

I have a couple of UITableViewController classes and I just noticed that these methods are not being called:

-(void)viewWillAppear:(BOOL)animated;
-(void)viewDidAppear:(BOOL)animated;

I read at http://discussions.apple.com/thread.jspa?threadID=1529769&tstart=0 that I myself would have to call these methods when I click the view dispatchers, but this is strange, since it works for anything other than UITableViewController.

Also makes this a bit of an issue when I need the UITableViewCell to unselect in the UIViewController that pressed the UITableViewController.

Answer 6

The same thing can happen if you use the UITabViewController. You need to force a call to viewWillAppear by either calling UITabViewControllerDelegate or UINavigationControllerDelegate
