Remove UICollectionView cells on edit button - objective-c

Question

I am using a UICollectionView to retrieve images and labels stored in the Cloud database Parse.
I now need an option that will let me delete a certain image and its corresponding label.
I am looking for something such as the typical iPhone "Edit" button on the top right hand corner which displays a swipe animation with a delete button next to the cell. I'm aware that such a thing can be done on a UITableView through
[[self tableView] setEditing:YES animated:YES];
but I can't seem to find the equivalent for a UICollectionView anywhere.
Any help appreciated, even if it doesn't deal with the deletion from Parse itself, just the editing style on the collection view would be ideal.
Here is how I populate my cells:
- (void)viewDidLoad
{
[super viewDidLoad];
[self retrieveSelectedImages];
}
-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
return 1;
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
return [imageFilesArray count];
}
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"myRoomsCell";
MyRoomsCell *cell = (MyRoomsCell *)[collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
PFObject *imageObject = [imageFilesArray objectAtIndex:indexPath.row];
PFFile *imageFile = [imageObject objectForKey:#"imageFile"];
cell.loadingSpinner.hidden = NO; //show loading spinner to indicate work is happening until the image loads
[cell.loadingSpinner startAnimating];
// UILabel *label = (UILabel*) [cell viewWithTag:5];
cell.label.text= [imageObject objectForKey:#"roomLabel"]; //set room label as the label stored on parse previously inserted by the user
cell.label.font = [UIFont fontWithName:#"Helvetica-Bold" size:18];
cell.label.textAlignment = NSTextAlignmentCenter;
[imageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error)
{
if (!error) {
cell.parseImage.image = [UIImage imageWithData:data];
[cell.loadingSpinner stopAnimating];
cell.loadingSpinner.hidden = YES;
}
}];
return cell;
}
-(void) retrieveSelectedImages
{
//parse query where we search the favorites array column and return any entry where the array contains the logged in user objectid
PFQuery *getFavorites = [PFQuery queryWithClassName:#"collectionViewData"];
[getFavorites whereKey:#"selectedImage" equalTo:[PFUser currentUser].objectId];
[getFavorites findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error)
{
imageFilesArray = [[NSArray alloc] initWithArray:objects];
[roomsCollection reloadData];
}
}];
}

Basically, there is no Apple-provided way to do this.
There are also some really nice libraries. My personal favorite is DraggableCollectionView, and also check out LXReorderableCollectionViewFlowLayout.

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
[[Singleton sharedSingleton].selectedProfileArray removeObjectAtIndex:indexPath.row];
[selectCollectionView reloadData];
}
