UIImageView won't load image in UICollectionViewCell

I'm new to UICollectionViews. I have setup a basic UICollectionViewController with rows of 2 cells. In the controller I have one cell and I dragged a UIImageView into it. I connected it to the custom cell class. I made sure so change the class of the cell to this one in the interface builder also. In my view controller I have this code: 

@implementation StickersViewController

static NSString * const reuseIdentifier = @"stickerCell";

- (void)viewDidLoad {
    [super viewDidLoad];




    [self.collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:reuseIdentifier];


    //Add the images
    self.images = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"one.png"], [UIImage imageNamed:@"two.png"], [UIImage imageNamed:@"three.png"], nil];


}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


#pragma mark <UICollectionViewDataSource>

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {

    return 1;
}


- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {

    return [self.images count];
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    StickerCell *cell = (StickerCell *)[collectionView dequeueReusableCellWithReuseIdentifier:reuseIdentifier forIndexPath:indexPath];

    cell.imageView.image=self.images[indexPath.row];

    return cell;
}

I am getting this error when running the code: UICollectionViewCell imageView]: unrecognized selector sent to instance 0x7fe8e0e7828. Not sure why. Seems I have connected things up correctly. Could someone give me some pointers to where I might be going wrong please?

refer this tutorial http://www.raywenderlich.com/22324/beginning-uicollectionview-in-ios-6-part-12
you will get the right answer. probably i think you don't set the collection reusable view identifier
select collection view cell goto attribute inspector and set the collection reusable view identifier = cell

The problem is here:

[self.collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:reuseIdentifier];

where you're registering a UICollectionViewCell instead of your custom subclass. So that should be:

[self.collectionView registerClass:[StickerCell class] forCellWithReuseIdentifier:reuseIdentifier];

Also, keep in mind that in case that the setup is done in a Storyboard you do not need to register the class yourself since it is automatically handled for you (provided that you have set a custom class & a reuse identifier)

I hope that this makes sense
