uicollectionviewcell

问题 I am interested in having a collectionview as a part of a collection view cell but for some reason cannot figure out how this would be done. Where would I implement the necessary methods for the cells collectionview? 回答1: There's an article that Ash Furrow wrote that explains how to put an UICollectionView inside an UITableViewCell . It's basically the same idea when using it inside an UICollectionViewCell . 回答2: Everything is done programatically. No storyboards. I added a UICollectionView

问题 Problem looks like this: http://i.imgur.com/5iaAiGQ.mp4 (red is a color of cell.contentView) Here is the code: https://github.com/nezhyborets/UICollectionViewContentsAnimationProblem Current status: The content of UICollectionViewCell's contentView does not animate alongside contentView frame change. It gets the size immediately without animation. Other issues faced when doing the task: The contentView was not animating alongside cell's frame change either, until i did this in

问题 This isn't so much a question as an explanation of how to solve this problem. The first thing to realize is that the UICollectionView does inherit from a UIScrollView - so doing a standard lookup with a scroll view's content is the best solution. Here's the problem I was addressing: I had a UICollectionView that had differing items in each cell - along with differing types of cells. I need the selection of a cell to cause an effect of the image in the cell to appear to expand and take over

问题 I have an old project done by a developer some times ago.. This particular project has 3 collection views such as collectionAnnouncments, collectionNews and collectionBulletin. The first collectionview collectionAnnouncments is loading a same cell 10 times. But other two sections loading the cell correctly one time as per the response count. I don't have any idea up to now for this problem. I tried some solutions from the google but I couldn't sorted because of the bad UI and Code

问题 I'm having an issue in my cellForItemAtIndexPath where I am setting an image to my cell's UIButton but every time I scroll the collectionView's cells, it's placing the image on top of the already set image again and again. I can tell because the shadow of the image is getting thicker and thicker. I'm pulling the images from an array that I created of image literals in that swift file and the correct images are loading so there's no problem there. I'm sure this is a simple fix for most but I

问题 I am encountering a problem on landscape orientation for my collection view cell. When the app is in portrait it gives me the correct number of cell per row which is 2. But when I rotate my app to landscape it display 1 cell per row. Here's the screen of what I got: Portrait: Landscape: Here's my code for adding the size of the cell: func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) ->

问题 I'm trying to decide view heights based on a model property, but as UICollectionView is scrolled up and down, incorrect heights are assigned to visible cells. It seems that setting a HeightAnchor in GetCell (i.e. cellForItemAtIndexPath ) does not work. How can I make this work? using CoreGraphics; using Foundation; using System; using System.Collections.Generic; using UIKit; namespace App2 { public partial class ViewController : UIViewController { private UICollectionView _collectionView;

问题 I have designed a UICollectionViewCell using XIB and in that custom cell I have an UILabel whose user interaction I have enabled. In my viewcontroller when I am designing the cell , Here is my code. UITapGestureRecognizer *buyNowTapped = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(buyNowClicked:)]; buyNowTapped.numberOfTapsRequired = 1.0; cell.buy.tag = indexPath.row; cell.buy.userInteractionEnabled = YES; [cell.buy addGestureRecognizer:buyNowTapped]; -(void

问题 I have a collection view that I want to display hourly weather in. I seem to have a problem with loading the cell, and for some reason scrolling forwards and then back loads the cell fully. Before I scroll the collection view, all of the constraints do not work and one label doesn't show it's info. Before scrolling After scrolling (this is how I want the cells to look like) func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int { // #warning Incomplete implementation,
