Question

我在ios应用程序中使用了pagemenu视图，方法是https://github.com/uacaps/PageMenu

在menuviewcontroller中我有一个导航栏，左侧有我的slidemenu按钮，右侧有条形按钮项目（我在故事栏中添加了选择的照片）

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

所以根据点击我想隐藏/显示栏按钮项目（这意味着只有EMR标签我想显示栏按钮项目（选择照片）否则我想隐藏（提醒3个标签），但我无法实现它这是我在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];

}

查看我附上的截图

所以我想为emr选项卡以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，那些不是每次都在调用菜单（病人，EMR，聊天，处方），所以我不知道如何实现它请任何人帮我这个

提前致谢

这对我来说是这个问题中已接受的答案

添加此行

pagingMenuViewController.delegate=self;

在对象（pagingMenuViewController）之后启动

  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 CAPSPageMenuDelegate ansd委托方法

- (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
    }

}

Answer 2

确保在创建实例

后分配委托属性

_pagingMenuView.delegate = self

其他隐藏，显示您可以在委托方法中处理的业务

Answer 3

@sathya chinnasamy它什么都没有。您可以在这里使用NSNotificationCenter。

//将此代码粘贴到导航栏类

[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(playerStatus:) name:@"hideNavigationButton" object:nil];

- (void) playerStatus:(NSNotification *) notification
{
// hide navigation button.
}

//When you tap the button call this method

[[NSNotificationCenter defaultCenter]postNotificationName:@"hideNavigationButton" object:nil];

pagemenu-navigation右栏按钮项（根据标签无法隐藏）
