如何从集合视图中删除单元格？

Question

当用户LOCATION 'hdfs://hadoop1:9000/logHive/unLock/${hiveconf:logdir}'（按钮）删除单元格时，我想从UICollectionview删除单元格。

这是我的代码：

touchUpInside

我做错了什么？

Answer 1

为您的删除按钮设置标记以获取当前单元格/知道您点击的单元格

cell.deleteBtn?.tag = indexPath.row
cell.deleteBtn?.addTarget(self, action: #selector(yourVCName. deleteColor(_:)), for: .touchUpInside)

并调用

@IBAction func deleteColor(_ sender: UIButton){
   print("Button pressed  ")
  // continue your work

           var hitPoint = sender.convert(CGPoint.zero, to: yourCollectionViewName)
   var hitIndex: IndexPath? = yourCollectionViewName.indexPathForRow(at: hitPoint)

        self.items.remove(at: hitIndex.row)
          self.yourCollectionViewName.performBatchUpdates({
    self.yourCollectionViewName.deleteItems(at: [hitIndex])
}) { (finished) in
    self.yourCollectionViewName.reloadItems(at: self.yourCollectionViewName.indexPathsForVisibleItems)
}

 }
