The (UITableView*)tableView object in a UITableViewController is created when
it's needed. So you won't see it in the default nib. The style of the tableView
can only be set when it is created. If you want to customize the creation of
the tableView, you can do it either of two ways:
1. Add you own UITableView object (with the group style, if you want it) in the
UITableViewController's nib and hook it up to the UITableViewController's
tableView outlet.
or:
2. Intercept the dynamic creation of the tableView in code, overriding the
style of the created table. In the code of your subclass of
UITableViewController, add this (or just uncomment and tweak it if it's already
there from the template):
- (id)initWithStyle:(UITableViewStyle)style
{ // Override initWithStyle: if you create the controller
programmatically and want to perform customization that is not appropriate for
viewDidLoad.
self = [super initWithStyle:UITableViewStyleGrouped];
if (self != nil)
{
// any further customizations here
}
return self;
}
Here's the relevant documentation for the IUTableViewController class:
initWithStyle:
Initializes a table-view controller to manage a table view of a given style.
- (id)initWithStyle:(UITableViewStyle)style
Parameters
style
A constant that specifies the style of table view that the controller object is
to manage (UITableViewStylePlain orUITableViewStyleGrouped).
Return Value
An initialized UITableViewController object or nil if the object couldn’t be
created.
Discussion
If you use the standard init method to initialize a UITableViewController
object, a table view in the plain style is created.
Hope this helps,
