Ios Xcode-UICollectionView应选择vs didSelect

函数shouldSelectItemAtIndexPath的工作方式与DidDecelectItemAtIndexPath的工作方式完全相同。DidDextIndexPath以随机方式处理某些单元格，而不是另一个单元格。那么这里的问题是什么

编辑：这是一个输入错误，我用了DidDescelectItemAtIndexPath而不是didSelectItemAtIndexPath

也许是因为你用了DidDescelect而不是DidSelecte？编码最糟糕的感觉是当你觉得自己很愚蠢的时候：我们都去过那里。。。

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

        if let selectedItem = collectionView?.indexPathForCell(sender as UICollectionViewCell) {

        if segue.identifier == "next" {

            var second: SecondViewController = segue.destinationViewController as SecondViewController
            second.itemNumber = selectedItem.row

        }
        }
    }

 override func collectionView(collectionView: UICollectionView, shouldSelectItemAtIndexPath indexPath: NSIndexPath) -> Bool {

        if let cell = collectionView.cellForItemAtIndexPath(indexPath) {
            performSegueWithIdentifier("next", sender: cell)
        } 
        return true
    }

    override func collectionView(collectionView: UICollectionView, didDeselectItemAtIndexPath indexPath: NSIndexPath) {


    }
