uicollectionviewcell

I've set the width of a cell(UICollectionViewCell) to be equal to the width of the UICollectionView and I'm trying to do exactly the same thing with the UILabel that is included inside that cell. I think the code below explains exactly what I'm trying to achieve. So i've read some question here in SO and also a couple of tutorials but I'm still not sure how I can achieve this. In a couple of questions it was saying about using collectionViewLayout but I'm really struggling on how to use it within my code. Any ideas? Thank you! func collectionView(collectionView: UICollectionView,

I am displaying dynamic images recieved from server in a horizontal collection view. When I set up the collectionview I set this: -(void)setupCollectionView{ [self setupPageControlView]; self.screensCollectionView.delegate=self; self.screensCollectionView.dataSource=self; [self.screensCollectionView registerNib:[UINib nibWithNibName:@"FGAppScreensCollectionViewItemCell" bundle:nil] forCellWithReuseIdentifier:@"screenCell"]; UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init]; [flowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal]; [flowLayout

This question has been asked a few times but none of the answers are detailed enough for me to understand why/how things work. For reference the other SO questions are: How to update size of cells in UICollectionView after cell data is set? Resize UICollectionView cells after their data has been set Where to determine the height of a dynamically sized UICollectionViewCell? I'm using MVC but to keep things simple lets say that I have a ViewController that in ViewWillAppear calls a web service to load some data. When the data has been loaded it calls [self.collectionView reloadData] The self

I have defined in my Storyboard (iPad) a view that contains a UICollectionView , at the bottom of the view there's also a UIToolbar . In the UICollectionView I have added a UICollectionViewCell (implemented by an iPadCellCollectionViewCell class) that contains a another view that is a Core-Plot Graph (a CPTGraphHostingView class). I have a class called X that implements the UICollectionViewDelegate and UICollectionViewDataSource . In the class X, I build for each cell of my view (in ViewDidLoad ) the Core-Plot Graph and I have the following code to link the graph to the cell of the

I am having similar problem like this I am generating height of view at run time.Here is my code @interface CollectionViewController () { NSMutableArray *arrMain; } @property(nonatomic,strong) NSMutableArray *arrMain; @end @implementation CollectionViewController @synthesize arrMain, - (void)viewDidLoad { [super viewDidLoad]; [cView registerNib:[UINib nibWithNibName:@"CViewCell" bundle:nil] forCellWithReuseIdentifier:kCellID]; CViewFlowLayout *fl = [[CViewFlowLayout alloc] init]; self.cView.collectionViewLayout = fl; NSString *strJson = MY FUNCTION WHICH RETURNS JSON STRING; SBJSON *parser = [

I have a FollowVC and FollowCell Setup with collection View. I can display all the datas correctly into my uIcollection view cell using the following code with no problem. func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell { if let cell = collectionView.dequeueReusableCellWithReuseIdentifier("FollowCell", forIndexPath: indexPath) as? FollowCell { let post = posts[indexPath.row] cell.configureCell(post, img: img) if cell.selected == true { cell.checkImg.hidden = false } else { cell.checkImg.hidden = true } return cell } }

Recently, I encountered a problem with the Interface Builder which I failed to solve. I'm using a UICollectionViewController and whenever I add a Cell it immediately shows a orange rectangle (indicating a auto-layout update). Updating the frame/cell doesn't change anything. The warning associated with the orange marking reads "Expected: height=Y, Actual: height=X" where Y is always exactly X-100. That is: When I set a custom cell height of 193, it says "Expected: height=93". This happens no matter which size I enter. The problem with this is that I have many difficulties with the subviews and

I'm making use of UICollectionView and I need to scroll to first cell after click in a button. The button is located in a (big) header section in my collection view... when clicking int it, I need scroll to my first cell located bellow of this button. I created a action of this button, but I don't know how to scroll to first UICollectionViewCell. Can someone help me? Use this delegate method, setting the indexPath at the first position: Swift self.collectionView?.scrollToItemAtIndexPath(NSIndexPath(forItem: 0, inSection: 0), atScrollPosition: .Top, animated: true) Swift 3 self.collectionView?
