Playlists

VideoKit's playlist support lets your app skip through a list of videos with minimal to no loading time.

We support the following types of playlists:

Playlist	Description
VKPlaylist	Implement your own playlist filter
VKCustomPlaylist	Loads with a list of videos from our backend
VKUserPlaylist	Load videos based on a user identity
VKFilteredPlaylist	Filter list of videos by metadata
VKTagsPlaylist	Load videos by associated tags

VKPlaylist

public class VKMyOwnPlaylist: VKPlaylist {

    init(videos: [VKVideo]) {
        self.videos = videos
    }

}

VKCustomPlaylist

Retrieve videos with ids 1a073e79-82d0-4d09-8640-44faa6ac0906 and 5fba1709-5cd5-4fb3-9b77-7987d550f9f3 and add them to the playlist

VKVideos.shared.get(byVideoIds: ["1a073e79-82d0-4d09-8640-44faa6ac0906", "5fba1709-5cd5-4fb3-9b77-7987d550f9f3"]) { (response: VKVideosResponse?, error: Error?) in
    if let videos = response?.videos {
        let playlist = VKCustomPlaylist(videos: videos)
    }
}

Retrieve videos with ids 1a073e79-82d0-4d09-8640-44faa6ac0906 and 5fba1709-5cd5-4fb3-9b77-7987d550f9f3 and let VKCustomPlaylist do the video fetching for you.

You can retrieve the videos using VKPlaylistDelegate.

let playlist = VKCustomPlaylist(videoIds: ["1a073e79-82d0-4d09-8640-44faa6ac0906", "5fba1709-5cd5-4fb3-9b77-7987d550f9f3"])
playlist.delegate = self

extension YourClass: VKPlaylistDelegate {
    func loaded(videos: [VKVideo]) {
        // videos loaded    
    }
}

Or alternatively through the VKPlaylistUpdated Notification

NotificationCenter.default.addObserver(forName: .VKPlaylistUpdated, object: self, queue: nil) { [weak self] (notification) in
    if let newIndexes = notification.userInfo["newIndexes"] as? [Int] {
        print("Updated playlist has \(newIndexes.count) videos.")
    }
}

let playlist = VKCustomPlaylist(videoIds: ["1a073e79-82d0-4d09-8640-44faa6ac0906", "5fba1709-5cd5-4fb3-9b77-7987d550f9f3"])

extension YourClass: VKPlaylistDelegate {
    func loaded(videos: [VKVideo]) {
        // videos loaded    
    }
}

VKUserPlaylist

let playlist = VKUserPlaylist(withUserIdentity: "unique-user-id")

VKFilteredPlaylist

let filter = VKVideoFilter()
let playlist = VKFilteredPlaylist(withFilter: filter, sortOrder: .asc)

VKTagsPlaylist

let playlist = VKTagsPlaylist(withTags: ["music", "dancing"], sortOrder: .asc)
