List all photo albums in iOS

Question

I need to get all photo albums on iPhone.

I know I can start an image picker to let the user selects an image from it. But I need to develop my own image browser.

All the code I found work with image picker or they already know album name.

I need first to list all photo albums names then the user will select one of them, then I will display images in this album.

All these steps will be done in customized layouts.

Can I list all photo albums?

Answer 1

Simple way to list all albums with image counts.

class AlbumModel {
    let name:String
    let count:Int
    let collection:PHAssetCollection
    init(name:String, count:Int, collection:PHAssetCollection) {
      self.name = name
      self.count = count
      self.collection = collection
    }
  }

func listAlbums() {
    var album:[AlbumModel] = [AlbumModel]()

    let options = PHFetchOptions()
    let userAlbums = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: options)
    userAlbums.enumerateObjects{ (object: AnyObject!, count: Int, stop: UnsafeMutablePointer) in
        if object is PHAssetCollection {
            let obj:PHAssetCollection = object as! PHAssetCollection

            let fetchOptions = PHFetchOptions()
            fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
            fetchOptions.predicate = NSPredicate(format: "mediaType = %d", PHAssetMediaType.image.rawValue)

            let newAlbum = AlbumModel(name: obj.localizedTitle!, count: obj.estimatedAssetCount, collection:obj)
            album.append(newAlbum)
        }
    }

    for item in album {
        print(item)
    }
}
