为什么 UICollectionView didSelect 方法不起作用? [英] Why UICollectionView didSelect method does not work?

问题描述

我以编程方式创建了我的 UICollectionView，在这种情况下，我的 didSelectItemAtIndexPath 方法根本没有调用.

I've created my UICollectionView programmatically and in this case my didSelectItemAtIndexPath method does not call at all.

let collectionView = UICollectionView(frame: CGRect(x: 0, y: 0, width: CGRectGetWidth(self.view.frame), height: 360), collectionViewLayout: layout)
collectionView.delegate = self
collectionView.dataSource = self
collectionView.userInteractionEnabled = true

那么，有什么问题吗?为什么当我点击单元格时我没有得到我的回应?

So, what is a problem? Why when I tap on the cells I do not get my response?

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    print("Selected Cell: \(indexPath.row)")
}

推荐答案

我知道这可能晚了，但为了功能目的，CollectionView[didSelectItem] 不响应触摸可能是由于您还启用了 addGestureRecognizer，因此请检查您是否在 CollectionView 上设置了手势识别器，就像 collectionView?.addGestureRecognizer(tapGestRecognizer)

i Know this may be late, but for the sakes of feature purpose, CollectionView[didSelectItem] not responding to touch could be as a result of you also enalbing addGestureRecognizer so check if you have set a gesture recognizer on your CollectionView like so collectionView?.addGestureRecognizer(tapGestRecognizer)
