uicollectionviewcell

I'm designing an iOS app with a UICollectionView, and I'd like users to be able to select multiple items within this view. It seems there's a standard style of checkmark Apple uses in this kind of situation. For example, in the image below you can see it when selecting multiple photos in a share sheet. According to the documentation , you are responsible for updating the UI of your cells to reflect their selection state. I know on a UITableViewCell you can set the accessoryType property to add a checkmark, but I can't seem to find any equivalent for a UICollectionViewCell. Is there a way Apple

I have a UICollectionView, that loads cells from reusable cell, which contains label. An array provides content for that label. I can resize label width depending on content width easily with sizeToFit. But I cannot make cell to fit label. Here's the code - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. arrayOfStats = @[@"time:",@"2",@"items:",@"10",@"difficulty:",@"hard",@"category:",@"main"]; } - (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection: (NSInteger)section{ return [arrayOfStats count

I am attempting to update a single cell inside a UICollectionView , specifically I am just trying to update an image in that specific cell detonated by cell.imageView . [self.collectionView reloadData] is not really an option because it makes the whole collection view flash. [self.collectionView beginUpdates] is not a thing in a UICollectionView it seems. I understand I may be able to use: [self.collectionView performBatchUpdates:^{ //do something } completion:nil]; I am not exactly sure what to put inside a completion block to update that certain cell's imageView . This is all being done

I'd like to customize the animation styles when a UICollectionViewCell is inserted and/or deleted. The reason why I need this is that by default I see that inserting a cell has a smooth fade in animation, however deleting a cell has a combination of move-to-the-left + fade out animation. I would be very happy with this if not for one problem. After I delete a cell, it is still reused when I add new ones, and when it's reused it's added not with the default fade in effect, but instead it's a combination of move-to-the-left + fade in. I'm not sure why I'm getting this inconsistency in animations

1) How can i achieve as shown in image with UICollectionView ? 2) I've tried -(CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath method & passed different sizes but it leaves out spaces between cells. Can i empty those spaces? I want different height & width for every cell Current output: . Sorry this is super late... But maybe this will help people who haven't found an answer yet. If you have your images in an array, you can simply reference the image size and make the adjustments to

When I try to put UICollectionCell to UICollectionView in Interface Builder I can't put it with unknown reasons. The cell is going to the tools bar without adding to UICollectionView I am using: iOS SDK 6.0 XCode 4.5.1 I don't use Storyboard Only UICollectionView inside StoryBoard have UICollectionViewCell inside. If use XIB, create a new XIB with CellName.xib, add CollectionViewCell to it, specify name of UICollectionView custom class. After that use registerNib. Sample code: https://github.com/lequysang/TestCollectionViewWithXIB You cannot put UICollectionViewCell directly into the
