The pictures taken out of the iOS PHAsset custom album, the PHAsset of the same picture is different
I am making a picture selection. When exiting the page of the selected picture, the PHAsset value of the selected picture is saved, and one by one when coming in again Determine whether to select, but the PHAsset that appears with the same picture will change, but this phenomenon will not occur when accessing the system film album.
