Is it possible to reload only the data added in ios collectionView? Like notifyItemRangeInserted on Android?

Add data from the list and self.CollectionView.reloadData() will refresh the screen.

After scrolling, add data and call self.CollectionView.reloadData() I forgot about the previously drawn screen, and I can draw it again Is there a way to put only the data added to the bottom??

It's a self-answer Causes and Solutions Cause The cell contains an image and loads the image from an external URL. When loading is complete, the transparency level from 0 to 1 is slowly It was redrawn and blinking. Solution I can't help but draw the cell again when reloading, but I gave the existing drawing a separator Redrawing started with a transparency of 1. This does not cause a blinking problem.
