[英]How to get indexPath of UICollectionViewCell based on cell text?
[英]How can I get the indexPath of a UICollectionViewCell and save it
我有一個UICollectionView
,其中有48個正方形。 我希望代碼知道用戶選擇了哪個UICollectionViewCell
。 用戶選擇了UICollectionViewCell
之后,用戶必須按下該VC
的顏色。
如何獲得所選的單元格?
我這樣做:
func selectedCell (at indexPath: IndexPath) {
let indexPathForFirstRow = indexPath
gamePad.selectItem(at: indexPathForFirstRow, animated: false, scrollPosition: UICollectionView.ScrollPosition(rawValue: 0))
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let cell: UICollectionViewCell = gamePad.cellForItem(at: indexPath)!
switch cell.backgroundColor {
case UIColor.lightGray:
cell.backgroundColor = UIColor.gray
case UIColor.gray:
cell.backgroundColor = UIColor.lightGray
default:
break
}
}
試試這個代碼
func selectedCell(forCell cell: UITableViewCell) -> IndexPath? {
let cellPosition: CGPoint = cell.convert(CGPoint.zero, to: self)
return self.indexPathForRow(at: cellPosition)
}
