I have a sidebar which I implemented using this: http://mobile.tutsplus.com/tutorials/iphone/implementing-container-containment-sliding-menu-controller/
However, I noticed that there isn't enough space above the first menu item as you can see here: 
Here is the code in my rootcontroller.m
#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;
}
