Ios 在侧边栏上方添加空间

我有一个侧边栏，我使用以下方法实现：

但是，我注意到第一个菜单项上方没有足够的空间，您可以在此处看到：

下面是我的rootcontroller.m中的代码

#define kExposedWidth 200.0
#define kMenuCellID @"MenuCell"

#import "RootController.h"

@interface RootController()

@property (nonatomic, strong) UITableView *menu;
@property (nonatomic, strong) NSArray *viewControllers;
@property (nonatomic, strong) NSArray *menuTitles;

@property (nonatomic, assign) NSInteger indexOfVisibleController;

@property (nonatomic, assign) BOOL isMenuVisible;

@end


@implementation RootController

- (id)initWithViewControllers:(NSArray *)viewControllers andMenuTitles:(NSArray *)menuTitles
{
    if (self = [super init])
    {
        NSAssert(self.viewControllers.count == self.menuTitles.count, @"There must be one and only one menu title corresponding to every view controller!");    // (1)
        NSMutableArray *tempVCs = [NSMutableArray arrayWithCapacity:viewControllers.count];

        self.menuTitles = [menuTitles copy];

        for (UIViewController *vc in viewControllers) // (2)
        {
            if (![vc isMemberOfClass:[UINavigationController class]])
            {
                [tempVCs addObject:[[UINavigationController alloc] initWithRootViewController:vc]];
            }
            else
                [tempVCs addObject:vc];

            UIBarButtonItem *revealMenuBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Menu" style:UIBarButtonItemStylePlain target:self action:@selector(toggleMenuVisibility:)]; // (3)

            UIViewController *topVC = ((UINavigationController *)tempVCs.lastObject).topViewController;
            topVC.navigationItem.leftBarButtonItems = [@[revealMenuBarButtonItem] arrayByAddingObjectsFromArray:topVC.navigationItem.leftBarButtonItems]; 


        }
        self.viewControllers = [tempVCs copy];
        self.menu = [[UITableView alloc] init]; // (4)
        self.menu.delegate = self;
        self.menu.dataSource = self;

    }
    return self;
}

{
    [super viewDidLoad];
    [self.menu registerClass:[UITableViewCell class] forCellReuseIdentifier:kMenuCellID];
    self.menu.frame = self.view.bounds;

    self.indexOfVisibleController = 0;
    UIViewController *visibleViewController = self.viewControllers[0];
    visibleViewController.view.frame = [self offScreenFrame];
    [self addChildViewController:visibleViewController]; // (5)
    [self.view addSubview:visibleViewController.view]; // (6)
    self.isMenuVisible = YES;
    [self adjustContentFrameAccordingToMenuVisibility]; // (7)


    [self.viewControllers[0] didMoveToParentViewController:self]; // (8)

}

- (void)toggleMenuVisibility:(id)sender // (9)
{
    self.isMenuVisible = !self.isMenuVisible;
    [self adjustContentFrameAccordingToMenuVisibility];
}


- (void)adjustContentFrameAccordingToMenuVisibility // (10)

给你的部分标题加上高度，它会在第一行上方增加空间

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { 
    return 40; //set this value
}

你真正的问题是处理应用程序顶部的状态栏

您是否希望在应用程序正在使用时状态栏挂起？然后，你可能会考虑将整个界面击倒20秒（除非你真的希望状态栏与内容重叠）

---

或者，您可以在整个应用程序中隐藏状态栏，或者仅在特定的ViewController中隐藏状态栏。

您是指

“Carrier”

和

“Cheats”

之间的空间吗？是的，先生。我只需要添加一些空白。添加到您的RootController。
