This will ensure that all instances of
ItemsViewController
use the
UIT-
ableViewStyleGrouped
style, no matter what initialization message is sent to it.
Open
HomepwnerAppDelegate.m
. In
applica-
tion:didFinishLaunchingWithOptions:
, create an instance of
Item-
sViewController
and set it as the
rootViewController
of the window. Make
sure to import the header file for
ItemsViewController
at the top of this file.
#import "ItemsViewController.h"
@implementation HomepwnerAppDelegate
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
// Create a ItemsViewController
ItemsViewController *itemsViewController = [[ItemsViewController alloc] init];
// Place ItemsViewController's table view in the window hierarchy
[[self window] setRootViewController:itemsViewController];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
Build and run your application. You will see the default appearance of a plain
UIT-
ableView
with no content, as shown in
Figure 9.5
.
How did you get a table view? As a
subclass of
UIViewController
, a
UITableViewController
inherits the
view
method. This method calls
loadView
, which creates and loads an empty view object if
none exists. A
UITableViewController
's
view
is always an instance of
UIT-
ableView
, so sending
view
to the
UITableViewController
gets you a bright,
shiny, and empty table view.
