uicollectionviewcell

问题 I've noticed iOS it's very mean when using UICollectionView inside an UITableViewCell . What I'm trying to achieve, it's to have a Collection of Images ( UICollectionView approach) inside a UITableViewCell . I'm trying to mimic Facebook post style, I think, they have an UITableView , with custom cells and so on, but here's the Problem... I've managed to put the UICollectionView inside an UITableViewCell , and It worked correctly and perfectly, no problem, everything showing fine, it's

问题 I am trying to add shadow to my custom UICollectionViewCell , This is the code I am using in my custom collection view cell class: self.layer.shadowOffset = CGSizeMake(1, 0); self.layer.shadowColor = [[UIColor blackColor] CGColor]; self.layer.shadowRadius = 5; self.layer.shadowOpacity = .25; This is giving shadow to the components of the collection view cell. 回答1: Don't forget to add these 2 lines self.clipsToBounds = false self.layer.masksToBounds = false 回答2: Swift 4.2 and xcode 10 here's

问题 I dynamically set width of each cell of UICollectionView according to text inside it. The problem is that most of the time the width size is correct but sometimes cell size is not correct. These are strings i displayed in cell let tabs = ["1st tab", "Second Tab Second", "Third Tab", "4th Tab", "A"] func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { let text = tabs[indexPath.row] let font

问题 I have an app that been happily shipping for a couple of years. It retrieves RSS Feeds in a UICollectionView. The cellForItemAtIndexPath method sets text and calls a datasource method to load an image from a link specified in the feed. If none exists it loads the web page data and searches for <img> tags to get an image. Once the image is found/loaded the delegate method is called to add the image to the cell. (below) When running in iOS 8 and 9 everything is happy, but when running in iOS 10

问题 I have initialized the collection view like this: override init(frame: CGRect){ let layout = UICollectionViewFlowLayout() layout.scrollDirection = .horizontal layout.itemSize = UICollectionViewFlowLayoutAutomaticSize layout.estimatedItemSize = CGSize(width: 100, height: 30) countryCollectionView = UICollectionView(frame: CGRect.zero, collectionViewLayout: layout) viewTitleLabel = UILabel() super.init(frame: frame) setupTableView() sortedDummyData = dummyData.sorted(by: <) } And I return size

问题 I have a cell that takes up the entire screen so there is only 1 visible cell at a time. Inside the cell I have an AVPlayer. Inside the cell's parent vc I have a KVO observer that listens to the "timeControlStatus" . When the player stops playing I call a function stopVideo() inside the cell to stop the player and either show a replay button or a play button etc. 3 problems: 1- When the video stops/reaches end if I don't use DispatchQueue inside the KVO the app crashes when the cell's
