我在我的应用程序中使用它作为侧边菜单：https ://github.com/romaonthego/RESideMenu

但是，我在让它与两个数组一起工作时遇到了问题。如果用户登录，我希望我的 RESideMenu 显示某个菜单项数组，如果没有用户，则显示不同的菜单项数组。

假设我打开了应用程序，但我没有登录，如果我打开菜单就会显示正确的菜单。但是，如果我然后登录，如果我再次打开它，菜单不会改变，它保持不变，就好像我没有登录一样。现在，如果我打开应用程序，但我没有登录，那么我登录，然后将应用程序退出多任务处理，再次打开它，现在显示“登录”菜单！

这是我的菜单视图的 .h 文件中的代码：

//
//  JSAMenuViewController.h
//  JSApp
//
//  Created by Jacob Klapper on 10/31/13.
//
//

#import <UIKit/UIKit.h>
#import "RESideMenu.h"

@interface JSAMenuViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, RESideMenuDelegate>

@property (strong, readwrite, nonatomic) UITableView *tableView;

@property NSArray *currentArray;

@property NSArray *inTitles;

@property NSArray *outTitles;

@end

为了在我的 tableview 菜单中实现/使用两个数组，我应该做一些不同的事情吗？

谢谢！

我相信我刚刚解决了我自己的问题哈哈。我正在尝试将更改数组的代码放在不同的方法中，并且这个方法有效：

- (void)sideMenu:(RESideMenu *)sideMenu willShowMenuViewController:(UIViewController *)menuViewController
{
    NSLog(@"willShowMenuViewController");

    self.inTitles = [NSArray arrayWithObjects:@"Login", @"Register", @"About Us", @"Who's Who", @"Request a Position", @"My Debates", @"Submit an Idea", @"Debates", @"Logout", nil];

    self.outTitles = [NSArray arrayWithObjects:@"Login", @"Register", @"About Us", @"Who's Who", nil];

    if([PFUser currentUser])
    {
        self.currentArray = self.inTitles;
        [self.tableView reloadData];
    }

    else
    {
        self.currentArray = self.outTitles;
        [self.tableView reloadData];
    }

    [self.tableView reloadData];
}

每次出现菜单时都会调用它。
