    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

- (IBAction)jump2two:(UIButton *)sender {
    //创建一个新的modal并弹出
    YYtwoViewController *two=[[YYtwoViewController alloc]init];
    //在two上用导航控制器包装，让弹出的模态窗口有一个导航栏可以放返回按钮
    UINavigationController *nvc=[[UINavigationController alloc]initWithRootViewController:two
                                 ];
    [self presentViewController:nvc animated:YES completion:^{
        NSLog(@"弹出一个模态窗口");
