    // Do any additional setup after loading the view.
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [self.navigationController.navigationBar setTranslucent:NO];//设置navigationbar的半透明

    self.title = @"RootViewController";//设置navigationbar上显示的标题

    [self.navigationController.navigationBar setBarTintColor:[UIColor purpleColor]];//设置navigationbar的颜色

    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonItemStyleDone target:self action:Nil];//设置navigationbar左边按钮

    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonItemStylePlain target:self action:Nil];//设置navigationbar右边按钮

    [self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];//设置navigationbar上左右按钮字体颜色

    //self.navigationItem.rightBarButtonItem setTarget:<#(id)#>
    //动态添加一个按钮


    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    button.frame = CGRectMake(0, 300, 300, 50);

    [button setTitle:@"新添加的动态按钮" forState: UIControlStateNormal];

    button.backgroundColor = [UIColor clearColor];

    button.tag = 2000;

    [button addTarget:self action:@selector(clicked:) forControlEvents:UIControlEventTouchUpInside];

    [self.view addSubview:button];

    }

    - (void)clicked:(id) sender{
    SecondViewController *second = [[SecondViewController alloc]init];
    [self.navigationController pushViewController:second animated:YES];
    //second.str = @"hello!!";
    [second release];
    }
    //这个是新按钮的响应函数
    -(IBAction) buttonClicked:(id)sender {

    delegate:self
    cancelButtonTitle:@"确定"
