Full Usage Example
import UIKit
final class ViewController: UIViewController {
lazy var testVideo: MediaDownloadable = {
return SingleMedia(imageURL: URL(string: "https://dummyimage.com/600&text=thumbnail")!,
isVideoThumbnail: true,
videoURL: URL(string: "http://jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v")!)
}()
lazy var media: [MediaDownloadable] = {
return [testVideo,
SingleMedia(imageURL: URL(string: "https://dummyimage.com/300")!),
SingleMedia(imageURL: URL(string: "https://dummyimage.com/600")!),
testVideo]
}()
@IBAction func onButtonTapped(_ sender: UIButton) {
let vm = FullScreenImageBrowserViewModel(media: media)
let browser = FullScreenImageBrowser(viewModel: vm)
present(browser, animated: true, completion: nil)
}
}
AlamofireImage Support
By default,
FullScreenImageBrowser
doesn't use any 3rd library, theSingleImage
usesURLSession
to fetch image. However it's designed to be compatible with any networking library, one good example is AlamofireImage
The following code snippet shows an example how to use AlamofireImage
to seamlessly integrated with FullScreenImageBrowser
.
import Foundation
import AlamofireImage
public class FullScreenImage: MediaDownloadable {
public var image: UIImage?
public var imageURL: URL?
public var videoURL: URL?
public var isVideoThumbnail: Bool
public init(imageURL: URL?, isVideoThumbnail: Bool = false, videoURL: URL? = nil) {
self.imageURL = imageURL
self.videoURL = videoURL
self.isVideoThumbnail = isVideoThumbnail
}
public func loadImageWithCompletionHandler(_ completion: @escaping (UIImage?, NSError?) -> Void) {
if let image = image {
completion(image, nil)
return
}
loadImageWithURL(imageURL, completion: completion)
}
// use any network calls you like
public func loadImageWithURL(_ url: URL?, completion: @escaping (_ image: UIImage?, _ error: NSError?) -> Void) {
guard let _url = url else {
completion(nil, NSError(domain: "FullScreenImageBrowserDomain",
code: -2,
userInfo: [ NSLocalizedDescriptionKey: "Image URL not found."]))
return
}
let urlRequest = URLRequest(url: _url)
downloader.download(urlRequest) { [weak self] response in
debugPrint(response.result)
if let remoteImage = response.result.value {
self?.image = remoteImage
completion(remoteImage, nil)
} else {
completion(nil, NSError(domain: "FullScreenImageBrowserDomain",
code: -1,
userInfo: [ NSLocalizedDescriptionKey: "Couldn't load image from remote"]))
}
}
}
}
