uicollectionviewcell

I have 2 nested UICollectionViews. The delegate for the outer collection view is the main view controller, and the inner collection views delegate is the UICollectionCell of the outer collection view. The outer collection view has only a label and the inner collection view in it - normally there would be seven of these, the inner collection view should contain 3 or 4 cells (containing 3 labels). The problem is that the inner collection view only seems to get updated twice (for the first 2 sets of data in the outer views) after that they repeat. Here is the cellForItemAtIndexPath for the outer

So this is a tvOS project in Swift. I have a custom UICollectionViewCell with a button as one of its subviews. I add a target to the button to allow it to interpret clicks. Here's a simplified version of the relevant code class CustomCell: UICollectionViewCell { var button:UIButton! override init(frame: CGRect) { super.init(frame: frame) button = UIButton(...) // Button is initialized with a frame button.userInteractionEnabled = true button.enabled = true button.addTarget(self, action: "pressed:", forControlEvents: .PrimaryActionTriggered) contentView.addSubview(button) } func pressed(sender:

I want to set corner radius with content mode as aspect fit using following code: cell.imgvAlbum.contentMode = UIViewContentModeScaleAspectFit; cell.imgvAlbum.clipsToBounds = YES; cell.imgvAlbum.layer.cornerRadius = 5.0f; but i am getting output only for content mode as aspect fit. I have also tried for: cell.imgvAlbum.layer.masksToBounds = YES; What to do for corner radius? Please suggest me some solution. Thanks in advance. Use below method to get a Rounded corner image with the specified radius for rounded corner, apply all your above properties as UIViewContentModeScaleAspectFit , clip to

I'm trying to change the text of a UILabel in a UICollectionViewCell after the UICollectionViewCell has loaded, when tapping a button . But the label doesn't update on the screen. The console shows that the text property of the label is updated, but it seems the label isn't redrawn with the new text. Is this a known problem with UICollectionViewCells ? Some kind of caching issue, perhaps? Do I need to reload the cell, or the entire collection view for the update to show? Because the cell is already loaded, no change in cell will happen until it's reloaded, so you can either reload the entire

I am trying to build a CollectionView for a list all programmatically in Swift without using Storyboard. I was able to add a tap gesture event to the cell. However, When I added a set of buttons to the UICollectionViewCell's contentView, the buttons do not receive any touch events. Inside Controller let sampleCollectionView = UICollectionView(frame: (..), collectionViewLayout: layout) //Register the UICollectionViewCell inside UICollectionView sampleCollectionView.registerClass(sampleCollectionViewCell.self, forCellWithReuseIdentifier: "sampleCell") //Add Tap Gesture event to the cell area let

EDIT : seems like same question as this I made collection view with custom layout and cell but my cell's positions were a little off so I decided to number them so that I could debug it easier. I followed this guy's answer to number my cell using labels. Somehow myLabel was nil and caused my app to crash. I believe I have connected the outlets correctly but maybe someone could provide a list for me to check if I am doing anything wrong. ViewController import UIKit class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate { @IBOutlet var gridView:
