Answer 1

Pretty much with a UISearchBar inside of -(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar you'd use [navigationController setNavigationBarHidden: YES animated:YES] which animates it to hide when you click inside of the search bar, then inside of - (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar you'd use [navigationController setNavigationBarHidden: NO animated:YES] which animates it returning into the view.

In the UITextView 's Delegate you get two methods that are essentially the same.

- (void)textViewDidBeginEditing:(UITextView *)textView

Where you would put [navigationController setNavigationBarHidden: YES animated:YES]

- (void)textViewDidEndEditing:(UITextView *)textView

Where you would put [navigationController setNavigationBarHidden: NO animated:YES]
