为什么 UICollectionView didSelect 方法不起作用?

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)
