rjv*_*nti 3 ios swift phassetcollection
我是Swift的新手,我正在尝试创建一个函数,只需使用fetchAssetCollections返回截屏相册中的照片数量
我有
func getNumScreenshots() -> Int {
let collection:PHFetchResult =
PHAssetCollection.fetchAssetCollections(with: .album, subtype:.smartAlbumScreenshots, options: nil)
return collection.count
}

但是,这总是返回3,我不知道为什么(我的iPhone上有600个截图).
你可以尝试这个:
let albumsPhoto:PHFetchResult<PHAssetCollection> = PHAssetCollection.fetchAssetCollections(with: .smartAlbum, subtype: .albumRegular, options: nil)
albumsPhoto.enumerateObjects({(collection, index, object) in
if collection.localizedTitle == "Screenshots"{
let photoInAlbum = PHAsset.fetchAssets(in: collection, options: nil)
print(photoInAlbum.count) //Screenshots albums count
}
})
