jquery - 如何隐藏和显示同一栏按钮项目上的 View 按下

Question

我以编程方式创建了一个右栏按钮项。 Andi 在我的 View Controller 中放置了一个 UIVIEW。我已经为我的 bar button item 添加了操作。但现在我所做的是，第一次我的 UIVIEW 将被隐藏。当我的条形按钮项目按下时，应该显示我的 UIVIEW。

我需要的是，当单击同一个按钮时，我的同一个 UIVIEW 应该隐藏和显示。这是我的代码；

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    _barButton.target = self.revealViewController;
    _barButton.action = @selector(revealToggle:);

    [self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

    UIBarButtonItem *chkmanuaaly = [[UIBarButtonItem alloc]initWithTitle:@"Demo "style:UIBarButtonItemStylePlain target:self action:@selector(nextview)];
    self.navigationItem.rightBarButtonItem=chkmanuaaly;

    RightMenu.hidden = YES;




}
-(void)nextview{
    NSLog(@"Right button pressed");

    RightMenu.hidden = NO;



}

我怎样才能再次隐藏我按下相同的右栏按钮项。

请帮帮我，谢谢

我已经检查了这段代码。这会起作用:

@implementation viewcontroller
    bool isShown = false;

    - (void)viewDidLoad {
        [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
        [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
        _barButton.target = self.revealViewController;
        _barButton.action = @selector(revealToggle:);

        [self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

        UIBarButtonItem *chkmanuaaly = [[UIBarButtonItem alloc]initWithTitle:@"Demo "style:UIBarButtonItemStylePlain target:self action:@selector(nextview)];
        self.navigationItem.rightBarButtonItem=chkmanuaaly;

        RightMenu.hidden = YES;




    }
    -(void)nextview{
        NSLog(@"Right button pressed");

        if (!isShown) {
            RightMenu.hidden = NO;

            isShown = true;
        } else {
             RightMenu.hidden = YES;
            isShown = false;
        }



    }

如果可行，请告诉我。
