Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'UICollectionView must be initialized with a non-nil layout parameter

Question

I have the same code in three pages, but in two of them, this error occurs:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'UICollectionView must be initialised with a non-nil layout parameter

I don't understand why, if the code is the same in three pages and in the first page i don't have any problem.

My Code in header file

#import <UIKit/UIKit.h>

@interface CollectionViewController : UICollectionViewController<UICollectionViewDataSource>

@property (nonatomic,strong) NSMutableArray *marrImages;
@property (nonatomic,strong) NSMutableDictionary *mdictImageData;



@end

and in .m file

@interface CollectionViewController ()

@end

@implementation CollectionViewController


@synthesize marrImages,mdictImageData;

static NSString * const reuseIdentifier = @"cell";


- (void)viewDidLoad {
    [super viewDidLoad];

    //navigation bar
    UIImage *image = [UIImage imageNamed:@"home.png"];
    UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
    backButton.frame = CGRectMake(0, 0, 50, 50);
    [backButton setImage:image forState:UIControlStateNormal];
    //    [backButton addTarget:self action:@selector(leftButtonAcion:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithCustomView:backButton];
    self.navigationItem.leftBarButtonItem = button2;
    self.title = @"Welcome";

    marrImages=[[NSMutableArray alloc]init];

    mdictImageData=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"circlshadow_parking.png",@"imageFile",@"Estacionamentos",@"Info",nil];
    [marrImages addObject:mdictImageData];

   mdictImageData=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"circlshadow_charging.png",@"imageFile",@"Carregar Saldo",@"Info", nil];
    [marrImages addObject:mdictImageData];


}

This code:

    ParkingMenu *parkingMenu = [[ParkingMenu alloc] init];
    parkingMenu.modalPresentationStyle = UIModalPresentationPageSheet;
    parkingMenu.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    [self.navigationController pushViewController:parkingMenu animated:YES];
    [parkingMenu release];

shows that you're creating an instance of ParkingMenu without referencing the storyboard. Presumably this is a subclass of UICollectionViewController and is resulting in you not using the designated initialiser initWithCollectionViewLayout: or unarchiving from the storyboard (which would also set the layout).

You're also not using ARC, so you have to call release , which you shouldn't do really...

You need to update your code so it triggers a segue between the view controllers or so it loads the ParkingMenu from the storyboard by identifier.
