Question

我有swift集合视图并有项目，我想添加每个项目点击到数组和相同的项目再次点击将被删除数组。我的代码在这里。

我的阵列

var services = [""]

我的didSelectItemAtIndexPath代码

   func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {


           let clickeditem = items[indexPath.section].services[indexPath.item - 1]
                print(clickeditem) // here clicked item this item will be add to services array when first click, after clicked again will be remove in services array


    }

clickeditem //将在第一次点击时添加到services数组，再次点击后将在服务数组中删除

Answer 1

您可以使用结构，所以：

struct Item {
    let indexPath: NSIndexPath 
    let value: AnyObject
}

services.append(Item(indexPath, value: clickeditem))

然后删除你可以使用该indexPath迭代并检查元素：

for item in services {
    if item.indexPath == indexPath {
        //remove your item and whatever you want
    }
}

当单击添加/删除数组时，Swift Collection视图didSelectItemAtIndexPath
