Is there an API or a best practice to override default card height? The UI I have in mind is one that mimics Apple pay where cards are smaller.

Thanks,

I have tried to setup a section header using UICollectionReusableView. but, it is not showing up. Is there any way to achieve a section header with this library?

We are trying to display images from network in cell items. Our images were blinking simultaneously when scrolling MMCollectionView.

NumberOfItemsInSection method is keep calling when scroll the items. Why this is happening?

Pls suggest to solve this issue asap.

Thanks

This application is modifying the autolayout engine from a background thread after the engine was accessed from the main thread. This can lead to engine corruption and weird crashes.

I altered some things in your example ViewController.swift to give you the perspective I'm facing, those were the changes:

var titleArray = ["GIOVANNIJ","MARCO","IBITCI","GOD","DID","RUAN","APPEND","BIAJ","LELE","TETE"]

func generateCardInfo (cardCount:Int) -> [AnyObject] {
    var arr = [AnyObject]()
    let xibName = ["CardA"]//,"CardB","CardC"]
    
    for _ in 1...cardCount {
        let value = Int(arc4random_uniform(UInt32(xibName.count)))
        arr.append(xibName[value] as AnyObject)
    }

    return arr
}

func cardView(collectionView:UICollectionView,item:AnyObject,indexPath:IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: item as! String, for: indexPath )
    switch cell {
        case let c as CardACell:
            c.txtView.text = "Hello This is MMCardView ,Its a demo with different Card Type,This is a text type"
        
            c.labTitle.text = titleArray[indexPath.row]
        
        case let c as CardBCell:
            let v = Int(arc4random_uniform(5))+1
            c.imgV.image = UIImage.init(named: "image\(v)")            
        case let c as CardCCell:
            c.clickCallBack {
                if let vc = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "Second") as? SecondViewController {
                    vc.delegate = self
                    self.card.presentViewController(to: vc)
                }
            }
        default:
            return UICollectionViewCell()

    }
    return cell
}

@IBAction func filterAction () {
    let sheet = UIAlertController.init(title: "Filter", message: "Select you want to show in View", preferredStyle: .alert)

    sheet.addTextField(configurationHandler: nil)

        })
    })
    
    /*let cellA = UIAlertAction(title: "CellA", style: .default, handler: {

    sheet.addAction(cellAC)*/

    sheet.addAction(allCell)
    sheet.addAction(cancelAction)
    self.present(sheet, animated: true, completion: nil)
}

Now this is what I'm facing:

1. You have a pile of the same type cards differentiating them only by some sort of text (all of these are stored in an array).
2. You choose to filter those cards by some text, looking for the cards that contains that text you typed.
3. The filtering is done properly.
4. You choose to show all your cards, to go back to the original state.
5. Apparently everything is okay, but some cards are duplicated and some are missing.

Can you help me with this?

Hi,

Thank you for sharing the card view it looks very good. I'm having trouble to get the example working (I'm using Materials as well) card view is not showing. I did try to isolate and see if it is related to the cell, but if i just show the cell they will show in view. I'm doing it without storyboard. I'm not sure if i would be the cause of the problem. Only the first few lines of the code from example I changed just so that I can figure out why its not showing. However, I still couldn't figure out. It looks like objects were initiated under the card view, but the card view is not showing.

var card = CardView(frame: CGRect(x: 100, y: 200, width: 500, height: 500))

open override func viewDidLoad() {
    
    super.viewDidLoad()
    
    self.card.frame  = CGRect(x: 100, y: 200, width: 500, height: 500)
    self.card.backgroundColor = UIColor.red
    
    view.addSubview(self.card)
     self.card.cardDataSource = self
    self.card.registerCardCell(c: CardACell.classForCoder(), nib: UINib.init(nibName: "CardACell", bundle: Bundle.main))
   
    prepareToolbar()
    let arr = self.generateCardInfo(cardCount: 10)
    self.card.set(cards: arr)
    
    

    self.card.showStyle(style: .cover)
    //view.layout(card).horizontally().center()
    
    view.backgroundColor = UIColor.purple
    
   
}
