UICollectionViewCell 检测点击

Question

I have UICollectionView in ViewController class and I also have a class for UICollectionViewCell .

I have some cells and I need to detect which cell was tapped. How can I detect that?

Answer 1

Use this delegate method

func collectionView(_ collectionView: UICollectionView, 
         didSelectItemAt indexPath: IndexPath) {

    let tappedCell = collectionView.cellForItem(at:indexPath) as! CustomCellClass
    print(tappedCell.tag)
}

//

collectionView.delegate = self

//

class CustomVC:UIViewController,UICollectionViewDelegate,UICollectionViewDataSource { --- }

Answer 2

In Swift 5 you can use the didSelectItemAt method:

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    print(indexPath) //will return [0, 0] for the first cell, [0, 1] for the second cell etc...
}
