UICollectionView的单元格选择无法快速运行

Question

I have written sample code here - when i tap button "Select" it should select all the cells of UICollectionView. But is does not work and no error is reported. Below is code

// collectionView is name of UICollectionView

let collectonViewCount = collectionView.numberOfItemsInSection(0);

        for i in 0...collectonViewCount {

            let indexPath = NSIndexPath(forRow: i, inSection: 0)
            collectionView.selectItemAtIndexPath(indexPath, animated: true, scrollPosition: .None)

        }

I'm not sure what could be wrong in the above code.

Answer 1

cybergeeeek,

you can try

for i in 0...collectonViewCount {
let indexPath = NSIndexPath(forRow: i, inSection: 0)
collectionView.delegate?.collectionView!(collectionView, didSelectItemAtIndexPath: indexPath)
}

This answer ofcourse assumes that you have set the collectionView delegate and have implemented didSelectItemAtIndexPath this will select the collectionView cell and will trigger didSelectItemAtIndexPath :)
