在我的申请,我试图使用该函数 [self.navigationCotroller presentModalViewController:nextVC动画:YES]; 然而,当它进入下一个视图,子视图完成整个屏幕(当然它确实) ,问题是,我怎么能添加栏按钮导致的看法回来?问题,同时使用presentModalViewController

我曾尝试使用

  1. self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"back" style:UIBarButtonItemStyleDone target:self action:@selector(Go)]; 
    

    在功能viewDidLoad中,但它没有工作,没有酒吧,甚至按钮显示

  2. UINavigationBar *bb = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 44)]; 
    self.NVBar = bb; 
    [self.view addSubview:bb]; 
    

然而,我不知道如何将barbutton添加到新的导航栏--- NVBar

你想给我一个解决方案吗?

您将需要弹出新的视图控制器,以便为导航栏设置为自动包括。

在视图控制器从上面的代码中,

//*** Hook up four buttons to these actions and play around with it for a 
//*** better sense of what is going on.  
//*** JSBViewController is the name of my test class 
//*** You should use your ViewController class that you are currently coding so 
//*** you can see the difference of pop/push versus present/dismiss inside of a    
//*** navigation controller 
-(IBAction)push:(id)sender 
{ 
    JSBViewController * viewController = [self.storyboard instantiateViewControllerWithIdentifier:NSStringFromClass([JSBViewController class])]; 
    [self.navigationController pushViewController:viewController animated:YES]; 
} 
-(IBAction)pop:(id)sender 
{ 
    [self.navigationController popViewControllerAnimated:YES]; 

} 
-(IBAction)present:(id)sender 
{ 
    JSBViewController * viewController = [self.storyboard instantiateViewControllerWithIdentifier:NSStringFromClass([JSBViewController class])]; 
    [self presentViewController:viewController animated:YES completion:nil]; 
} 
-(IBAction)dismiss:(id)sender 
{ 
    [self dismissViewControllerAnimated:YES completion:nil]; 
} 

您正在寻找的行为,你将需要使用push方法
[self.navigationController pushViewController:viewController animated:YES];

如果使用[self.navigationController pushViewController:picker animated:YES];来推下你的下一个VC,那么导航栏应该保持在最上面。然后你可以用`[self.navigationController popViewControllerAnimated:YES]来回弹。

这是相当非常规使用导航栏从一个模态视图回去。 `
