与UIViewController有区别，就是UITableViewController自身的带的是tableView。
AppDelegate.m
#import "AppDelegate.h"
#import "RootTableViewController.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
RootTableViewController *rootTVC = [[RootTableViewController alloc]initWithStyle:(UITableViewStyleGrouped)];
UINavigationController *ncRoot = [[UINavigationController alloc]initWithRootViewController:rootTVC];
self.window.rootViewController = ncRoot;
[self.window makeKeyAndVisible];
[ncRoot release];
ncRoot = nil;
[rootTVC release];
rootTVC = nil;
return YES;
}
解释：
1、与原来的UIViewController一样，创建出来的RootTableViewController的对象rootTVC，style可以用plain和grouped两种。
2、UINavigationController创建出来是用rootTVC作为参数创建的。

#import "AppDelegate.h"
#import "RootTableViewController.h"

解释：
1、UITableViewController已经帮我们封装了我们实现代理那些方法，就是上面那些注释起来的方法。
2、[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:kCELL_ID]，是对我们将要用到的cell进行注册。第一个参数，是UITableViewCell类，第二个参数，是我们设的宏定义，用来作为cell的重用字符。
