如何在选定的UicollectionView单元格上显示计数标签？

我有一个CalendArcollectionView，它显示为每月日历类似于iOS日历。因此，在该日历上，我必须显示用户以前已经选择的预选日期。但是我还需要将标签显示为对这些单元的限制（假设如果用户的预选为23,24,25,26，则在这些datecell用户上也应将1,2,3,4分别为右角标签。）。我该怎么做？ “ alt =”请参考附带的图像以获取更多理解”>

如果您已经选择了日期，则可以根据需要使用以下逻辑而在几乎没有修改的情况下使用以下逻辑。

您可以声明助手变量

// This is your list of pre-selected dates
let preselectedPeriod = [3,12,13,14,16,17,18,29,30]

// Counter variable to increase your selected dates range
var count = 0

cellforintemat看起来像这样。
注意：在这里我使用indexpath作为日历日期

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! Cell
    cell.layer.borderColor = UIColor.black.cgColor
    cell.layer.borderWidth = 0.5
    cell.dateLabel.text = "\(indexPath.row+1)"
    cell.rangeIndicatorLabel.textColor = .white
    cell.card.layer.cornerRadius = 5
    cell.card.layer.masksToBounds = true
    
    if preselectedPeriod.contains(indexPath.row+1) {
        count += 1
        cell.card.backgroundColor = UIColor.orange
        cell.dateLabel.textColor = .white
        cell.rangeIndicatorLabel.text = "\(count)"
    }else{
        cell.dateLabel.textColor = .black
        cell.card.backgroundColor = UIColor.white
        cell.rangeIndicatorLabel.text = ""
    }
    return cell
}

If you have already selected dates you can use the following logic with little modifications according to your requirement.

You can declare the helper variables

// This is your list of pre-selected dates
let preselectedPeriod = [3,12,13,14,16,17,18,29,30]

// Counter variable to increase your selected dates range
var count = 0

Your cellForIntemAt looks like this.
Note: Here I have used the indexPath as the calendar date

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! Cell
    cell.layer.borderColor = UIColor.black.cgColor
    cell.layer.borderWidth = 0.5
    cell.dateLabel.text = "\(indexPath.row+1)"
    cell.rangeIndicatorLabel.textColor = .white
    cell.card.layer.cornerRadius = 5
    cell.card.layer.masksToBounds = true
    
    if preselectedPeriod.contains(indexPath.row+1) {
        count += 1
        cell.card.backgroundColor = UIColor.orange
        cell.dateLabel.textColor = .white
        cell.rangeIndicatorLabel.text = "\(count)"
    }else{
        cell.dateLabel.textColor = .black
        cell.card.backgroundColor = UIColor.white
        cell.rangeIndicatorLabel.text = ""
    }
    return cell
}
