如何根据添加到画廊的日期对 Swift 中的照片进行排序

Question

My app has a requirement where photos are loaded from iPhone gallery and listed in the app. Currently the sort order is based on PHAsset creationDate property. I would like to know how we can sort the assets based on the date added as how we see in All photos on iPhone.

I could see that PHAsset properties creationDate , modificationDate and other dates(listed below) from PhAsset metadata are the same, which is the date taken of the photo.

1. DateTime
2. DateTimeDigitized
3. DateTimeOriginal

Is there a way to get the date added for a PHAsset ?

Answer 1

You should check out PHFetchOptions you would end up doing something like this

let fetchOptions = PHFetchOptions()
let sortOrder = [NSSortDescriptor(key: "creationDate", ascending: false)]
fetchOptions.sortDescriptors = sortOrder
