Swipe able, customizable card stack view, Tinder like card stack view based on UICollectionView. Cards UI

Hello, When I keep dragging the card here and there without moving it down, app crash in this line collectionView?.bringSubview(toFront: cell!)

in this method

//Define what card should we drag
    fileprivate func findDraggingCellByCoordinate(_ touchCoordinate: CGPoint) {
        if let indexPath = collectionView?.indexPathForItem(at: touchCoordinate) {
            if indexPath.item >= index {
                //top stack
                draggedCellPath = IndexPath(item: index, section: 0)
                initialCellCenter = collectionView?.cellForItem(at: draggedCellPath!)?.center
            } else {
                //bottomStack
                if (index > 0 ) {
                    draggedCellPath = IndexPath(item: index - 1, section: 0)
                }
                initialCellCenter = collectionView?.cellForItem(at: draggedCellPath!)?.center
            }
            
            //workaround for fix issue with zIndex
            let cell = collectionView!.cellForItem(at: draggedCellPath!)
            collectionView?.bringSubview(toFront: cell!)
            
        }
    }

How to overcome this issue. Please help me.

I've had to disable the swipe gestures as I've found them not to redraw the card stack properly. For example, swiping down a card can result in it disappearing. If I then drag up the 'invisible' card it suddenly appears.

I'm not having any problems with the Pan gesture.

i need swipe Card in down direction only. How can i achieve that? Also it is crashing when swipe up direction: error: fatal error: Can't form Range with upperBound < lowerBound

Hey!

Currently is there anyway to create multiple stacks of cards? I know it creates one stack at default but I need multiple stacks in my TisprCardStackViewController.

Is this supported? Thanks!

Ethan

Dear, congrats for your beautiful work! i have a question, is it possible to add new card in front of the current one and not on the bottom?

another question, is it possibile do have a func do delete a card after down effect? something like

func cardDidChangeState(cardIndex: Int) {
        removeFromStack(cardIndex)
}

thanks!

Example app crashes with error dyld: Library not loaded: @rpath/TisprCardStack.framework/TisprCardStack Referenced from: /var/containers/Bundle/Application/72BAA679-CBD0-494A-ADC4-5A59F5FC81AF/TisprCardStackExample.app/TisprCardStackExample Reason: image not found

I am still a newbie with swift. Any workaround for this and get the demo app running?

I want to do a delete function with this. Can you guide me how to do that. I did reloading the view after remove an object from the stack but it's crashing for me.

After I go to the next view and perform the delete action. then when come back my stack should be refreshed. In viewdidappear() I did this `

  if(dm.cardshouldRefresh || isFirsttimeLoad)
    {
        
        com.showProgress()
        
        self.getAuthorizations() { (status) in
            
            self.dm.cardshouldRefresh=false
            self.isFirsttimeLoad=false
            self.com.removeProgress()
            if (status)
            {
                self.setupCardView()

            }

        }
    }
    
    else
    {
        print(arrayAuthorization)
        
    }   
}

func makecollectionViewEmpty()
{
    arrayAuthorization.removeAll()
    vwBtnPanelBottom.removeFromSuperview()
    self.collectionView?.reloadData()
}

hi when i install code : pod 'TisprCardStack', '~> 0.3.1'

warning :

[!] Unable to read the license file `/Users/Javad/Desktop/balen/Pods/TisprCardStack/LICENSE.txt` for the spec `TisprCardStack (0.3.1)`

[!] Unable to read the license file `/Users/Javad/Desktop/balen/Pods/TisprCardStack/LICENSE.txt` for the spec `TisprCardStack (0.3.1)`

can you help me ? Thanks a lot

Using build:

pod 'TisprCardStack', '~> 0.2.0beta1'

Crashes with this error:

'-[UICollectionViewController loadView] loaded the "zvq-Xi-k6K-view-Ul4-59-zee" nib but didn't get a UICollectionView.'

Copied code from example project pretty much verbatim: (Storyboard contains proper UICollectionView and cell with correct identifier, datasource/delegate assignment, etc.)

override func viewDidLoad() {
    super.viewDidLoad()

    //set animation speed
    setAnimationSpeed(0.85)

    //set size of cards
    let size = CGSizeMake(view.bounds.width - 40, 2*view.bounds.height/3)
    setCardSize(size)

    cardStackDelegate = self

    //configuration of stacks
    layout.topStackMaximumSize = 4
    layout.bottomStackMaximumSize = 30
    layout.bottomStackCardHeight = 45
}

// MARK: TisprCardStackDataSource
override func numberOfCards() -> Int {
    return 10
}

override func card(collectionView: UICollectionView, cardForItemAtIndexPath indexPath: NSIndexPath) -> TisprCardStackViewCell {

    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("CellIdentifier", forIndexPath: indexPath) as! TisprCardStackDemoViewCell

    cell.backgroundColor = UIColor.purpleColor()
    //cell.text.text = "Card - \(indexPath.item)"

    return cell

}

// MARK: TisprCardStackDelegate
func cardDidChangeState(cardIndex: Int) {
    print("card with index - \(cardIndex) changed position")
}

The error Could not cast value of type 'UICollectionViewFlowLayout' to 'Swish.TisprCardStackViewLayout' appears each time I try and build this. I just dropped the three files into my project. Any ideas anyone?

Instead of what is there now we need to have this:

Added delegates for card bottom and card top movements. Further update the swift to reflect latest swift changes.

Hi, I have integrated your as well as new neighbourly app(by Google) like card view in this pull request. Please take a look and revert.

Regards, Nakash Jawahire

Hi, I have made changes in this code to make it horizontal scrolling with slight variation(similar to neighbourly app by google). For reference checkout my fork: https://github.com/njawahire/tispr-card-stack
