ios - swift UICollectionView : didSelectItemAtIndexPath not responding

Question

我在 ViewController 中有 UICollection View ，它根本不响应 didSelectItemAtIndexPath。

// super class
class ViewController: UIViewController, iCarouselDelegate, iCarouselDataSource, UICollectionViewDelegate, UICollectionViewDataSource {

    @IBOutlet weak var collectionView: UICollectionView!


// delegate
override func viewDidLoad() {
        super.viewDidLoad()

        // collection view delegate and datasource
        collectionView.delegate = self
        collectionView.dataSource = self


// did select item
        func collectionView(collectionView: UICollectionView!, didSelectItemAtIndexPath indexPath: NSIndexPath!) {

           print(indexPath)

        }

还有这位来自 IB 的代表。

Answer 1

一些猜测可能会有帮助:

• 您是否不小心覆盖了 - (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath？

• 确保将 collectionView.userInteractionEnabled 设置为 true

• 如果一些高优先级的UIResponder像UIGestureRecognizer和UIButton被添加到单元格或者它的 subview ，相应的方法应该被调用
