由 荒凉一梦 提交于 2019-12-01 00:04:05
So I have a cells in a collectionview with 3 buttons in it. To trigger code with these buttons I have implemented a custom delegate. Now the code is being triggered, but I don't know from which cell the code triggered. How can I best implement this? Here is some of my code. Protocol: protocol OverViewDelegate { func registerButtonClicked() func evaluateButtonClicked() func overviewButtonClicked() } cellForItemAt: func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCell(withReuseIdentifier

问题 I am using https://github.com/jessesquires/JSQMessagesViewController/issues/1820 this library for chat application. By using this libary I am able to send images and video, but my app needs to send one view with some button and text. Like when user sends some text it will appear to others as text and button and then when somebody clicks the button one push notification will be generated. I am not able to figure it out how can I achieve this. Here is screen shot how I want my custom view to be

Static or Prototype UITableViewCell subviews are resized incorrectly in Storyboard on Xcode 6.1.1, iOS 8.1 SDK

问题 So I updated to Xcode 6.1 earlier and 6.1.1 today . I notice that there's an issue while using Static / Prototype UITableViewCell (or Prototype UICollectionViewCell) in Storyboard. All the subviews with certain Autoresizing masks will be resized incorrectly when running on device / simulator. UISlider as a subView of the Static UITableViewCell Autoresizing rule is Flexible Width. Or Flexible LeftMargin also causes the problem. Observing the Slider is too long, went off the screen the the

UICollectionViewCell change cell size while scrolling

由 岁酱吖の 提交于 2019-11-30 15:34:03
问题 I'm trying to create a UICollectionView where the UICollectionViewCell is getting scaled down when "leaving" the visible area at the top or bottom. And getting scaled up to normal size while "entering" the visible area. I've been trying some scale/animation code in: scrollViewDidScroll() , but I can't seem to get it right. My complete function looks like this: func scrollViewDidScroll(scrollView: UIScrollView) { var arr = colView.indexPathsForVisibleItems() for indexPath in arr{ var cell =

Deleting cell at edge of UICollectionView - cells not appearing immediately after scroll

由 假如想象 提交于 2019-11-30 15:27:00
问题 Consider an standard, vertically scrolling flow layout populated with enough cells to cause scrolling. When scrolled to the bottom, if you delete an item such that the content size of the collection view must shrink to accommodate the new number of items (i.e. delete the last item on the bottom row), the row of cells that scroll in from the top are hidden. At the end of the deletion animation, the top row appears without animation - it's a very unpleasant effect. In slow motion: It's really

UICollectionViewCell using prototype sizes

由 穿精又带淫゛_ 提交于 2019-11-30 14:11:19
I have an UICollectionView with three different prototype cells, each of which with different heights set via Storyboard. During runtime, the Collection View uses its own cell size, ignoring my Storyboard ones. I am currently using collectionView:layout:sizeForItemAtIndexPath: with a couple conditionals to set each CGSize straight. Is there a better way to set the cell sizes? I don't seem to be able to retrieve the Storyboard size each cell has, and CGSizeMake seems too hardcoded and not really flexible.
