NSArray objectAtIndex index 1 bounds beyond [0,0]?

Question

My problem is that the first cell in each section works but if I have another cell in that section (index 1) it just crashes with that error.

I realize this question has been asked many times, but I have referenced the other questions and not have helped, I am getting the error:

Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 1 beyond bounds [0 .. 0]'

And the class where this problem is:

HERE IS MY .H,

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

@interface SidebarViewController : UITableViewController

@property (nonatomic, strong) NSArray *menuItems;
@property (nonatomic, strong) NSArray *fitnessItems;
@property (nonatomic, strong) NSArray *fitnessItemsImages;
@property (nonatomic, strong) NSArray *settingsItems;
@property (nonatomic, strong) NSArray *settingsItemsImages;
@property (nonatomic, strong) NSArray *allItems;


@end

HERE IS MY .M,

#import "SidebarViewController.h"
#import "UIColor+FlatUI.h"


@interface SidebarViewController ()

@end

@implementation SidebarViewController


- (void)viewDidLoad
{
[super viewDidLoad];

_menuItems = @[@"Home"];
_fitnessItems = @[@"Find Exercises",@"Workouts",@"Build Workouts"];
_settingsItems = @[@"Account", @"Preferences"];

Problem is in your prepareForSegue: method.

NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
UINavigationController *destViewController = (UINavigationController*)segue.destinationViewController;
destViewController.title = [[_menuItems objectAtIndex:indexPath.row] capitalizedString];

For example selected index path is 1.2 => your code is calling [_menuItems objectAtIndex:2] that raises the error.

Actual solution depends on what you want to do. If you want to perform the seague only when tapping on cell from first section you should change your didSelectRowAtIndexPath:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

    if (indexPath.section == 0)
         [self performSegueWithIdentifier:@"Test" sender:nil];

}

Otherwise you should change the destViewController.title = ... accordingly.

A tip that might want to help you find this kind of errors would be to set the breakpoints on exceptions.
