使用：

    ViewController* vc = [[ViewController alloc] init];    
    self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:vc];
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];

[self.navigationController pushViewController:xxx animated:YES];

[self.navigationController popViewControllerAnimated:YES];

    self.title = @"标题";    
    //设置背景颜色，下面三句话
    self.navigationController.navigationBar.backgroundColor = [UIColor blueColor];
    self.navigationController.navigationBar.translucent = YES; //设置背景为透明的
    self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
    
    self.navigationController.navigationBar.tintColor = [UIColor blueColor]; //设置按钮颜色
    //手动添加左右两个按钮，若不添加，左按钮自动生成，带有返回图标和上一个界面的标题
    UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Exit" style:UIBarButtonItemStylePlain target:self action:@selector(handleExit:)];
    self.navigationItem.leftBarButtonItem = backButton;
    UIBarButtonItem *setButton = [[UIBarButtonItem alloc] initWithTitle:@"设置" style:UIBarButtonItemStylePlain target:self action:@selector(setButtonAction:)];
    self.navigationItem.rightBarButtonItem = setButton;
