ios - pagemenu-navigation 右栏按钮项(不能按tabs隐藏)

Question

我在我的 iOS 应用程序中使用页面菜单 View ，方法是遵循此 https://github.com/uacaps/PageMenu

在 menuviewcontroller 中，我有一个导航栏，左侧有 slidemenu 按钮，右侧有条形按钮项(称为选择照片，我在 storybord 中添加)

在该导航栏下方，我添加了 pagemenu view 4 选项卡(包含患者、EMR、聊天、处方)

所以根据点击我想隐藏/显示那个条形按钮项(这意味着我只想显示条形按钮项(选择照片)的 EMR 选项卡，否则我想隐藏(重新挖掘 3 个选项卡)，但我达不到这是我在 menuviewcontroller viewdidload 方法中的代码

- (void)viewDidLoad {
    [super viewDidLoad]; 


    SWRevealViewController *revealViewController = self.revealViewController;
    if ( revealViewController )
    {
        [self->_slideOutMenu setTarget: self.revealViewController];
        [self->_slideOutMenu setAction: @selector( revealToggle: )];
        [self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

    }

    self.navigationController.navigationBar.shadowImage = [[UIImage alloc] init];
    [self.navigationController.navigationBar setBackgroundImage:[[UIImage alloc] init] forBarMetrics:UIBarMetricsDefault];
    self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
    self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
    self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor whiteColor]};



    UIStoryboard* sb = [UIStoryboard storyboardWithName:@"Main"
                                                 bundle:nil];
    Patient* controller1 = [sb instantiateViewControllerWithIdentifier:@"patient"];

    controller1.title = @"PATIENT";

    EMR* controller2 = [sb instantiateViewControllerWithIdentifier:@"emr"];

    controller2.title = @"EMR";
    Chat* controller3 = [sb instantiateViewControllerWithIdentifier:@"chatViewcontroller"];

    controller3.title = @"CHAT";

    Prescription* controller4 = [sb instantiateViewControllerWithIdentifier:@"prescription"];

    controller4.title = @"PRESCRIPTION";

    NSArray *controllerArray = @[controller1, controller2, controller3, controller4];
    NSDictionary *parameters = @{
                                 CAPSPageMenuOptionScrollMenuBackgroundColor: [UIColor colorWithRed:60.0/255.0 green:169.0/255.0 blue:128.0/255.0 alpha:1.0],
                                 CAPSPageMenuOptionViewBackgroundColor: [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],
                                 CAPSPageMenuOptionSelectionIndicatorColor: [UIColor whiteColor],
                                 CAPSPageMenuOptionBottomMenuHairlineColor: [UIColor colorWithRed:70.0/255.0 green:70.0/255.0 blue:70.0/255.0 alpha:1.0],
                                 CAPSPageMenuOptionMenuItemFont: [UIFont fontWithName:@"HelveticaNeue" size:12.0],
                                 CAPSPageMenuOptionMenuHeight: @(70.0),
                                 CAPSPageMenuOptionMenuItemWidth: @(120.0),
                                 CAPSPageMenuOptionCenterMenuItems: @(YES)
                                 };

    _pagingMenuView = [[CAPSPageMenu alloc] initWithViewControllers:controllerArray frame:CGRectMake(0.0, 42.0, self.view.frame.size.width, self.view.frame.size.height-38) options:parameters];
    if (_currentIndex >= 0 && _currentIndex <= 2){


        [_pagingMenuView moveToPage:_currentIndex];

    }
    [self.view addSubview:_pagingMenuView.view];

}

看我附上的截图

所以我想为除 emr 选项卡之外的所有选项卡隐藏右侧导航栏按钮viewdidload 和 viewwill 出现在 menuviewcontroller 中的方法只被调用一次，每次点击菜单时都不会调用这些方法(患者、EMR、聊天、处方)所以我不知道如何实现它请任何人帮助我

提前致谢

这对我来说是这个问题的公认答案

添加这一行

pagingMenuViewController.delegate=self;

在对象(pagingMenuViewController)启动后如下所示

  pagingMenuViewController = [[CAPSPageMenu alloc] initWithViewControllers:controllerArray frame:CGRectMake(0.0, 42.0, self.view.frame.size.width, self.view.frame.size.height-38) options:parameters];
    self.navigationItem.rightBarButtonItem.tintColor=[UIColor clearColor];

      pagingMenuViewController.delegate=self;

我添加了这个代表CAPPSageMenuDelegateansd 委托(delegate)方法

- (void)didMoveToPage:(UIViewController *)controller index:(NSInteger)index {
    if(index ==1){
        [self show];
    }else{
        [self hide];
    }
}
- (void)willMoveToPage:(UIViewController *)controller index:(NSInteger)index{
    if(index ==1){
        [self show];
    }else{
        [self hide];
    }
}

Answer 1

在viewDidLoad方法中添加

_pagingMenuView.delegate = self

然后实现委托(delegate)方法

- (void)didMoveToPage:(UIViewController *)controller index:(NSInteger)index {
    if(index ==1){
        self.navigationItem.rightBarButtonItem = //your barButton to select photo
        self.navigationItem.leftBarButtonItem = nil;
    }else{
        self.navigationItem.rightBarButtonItem = nil;
        self.navigationItem.leftBarButtonItem = //your barButton to reveal the slide menu
    }

}
