\n\n# A-J-Full-Screen-Image-Browser\n\n\n\n\n\n\nA-J-Full-Screen-Image-Browser is an drop-in solution for full screen image and video browser\n\n## Features\n\n- [x] No Dependency, 100% iOS Native\n- [x] Support both iPad and iPhone family\n- [x] Support image resizing on different screen orientation\n- [x] Support multiple videos and images\n- [x] Image can be panned, zoomed and rotated\n- [x] Double tap to zoom all the way in and again to zoom all the way out\n- [x] Swipe to dismiss\n- [x] High level diagram\n- [x] MVVM architecture\n- [x] Full documentation\n- [x] Easy to customise\n\n## Requirements\n\n- iOS 9.0+ / macOS 10.10+ / tvOS 9.0+ / watchOS 2.0+\n- Xcode 9.0+\n- Swift 4.0+\n\n## Installation\n\n- drag and drop the entire `A_J_Full_Screen_Image_Browser` into your project\n\n## Full Usage Example\n\n```swift\nimport UIKit\n\nfinal class ViewController: UIViewController {\n\n lazy var testVideo: MediaDownloadable = {\n return SingleMedia(imageURL: URL(string: \"https://dummyimage.com/600&text=thumbnail\")!,\n isVideoThumbnail: true,\n videoURL: URL(string: \"http://jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v\")!)\n }()\n\n lazy var media: [MediaDownloadable] = {\n return [testVideo,\n SingleMedia(imageURL: URL(string: \"https://dummyimage.com/300\")!),\n SingleMedia(imageURL: URL(string: \"https://dummyimage.com/600\")!),\n testVideo]\n }()\n\n @IBAction func onButtonTapped(_ sender: UIButton) {\n let vm = FullScreenImageBrowserViewModel(media: media)\n let browser = FullScreenImageBrowser(viewModel: vm)\n present(browser, animated: true, completion: nil)\n }\n\n}\n```\n\n## AlamofireImage Support\n\n> By default, `FullScreenImageBrowser` doesn't use any 3rd library, the `SingleImage` uses `URLSession` to fetch image. However it's designed to be compatible with any networking library, one good example is [AlamofireImage](https://github.com/Alamofire/AlamofireImage)\n\nThe following code snippet shows an example how to use `AlamofireImage` to seamlessly integrated with `FullScreenImageBrowser`.\n\n```swift\nimport Foundation\nimport AlamofireImage\n\npublic class FullScreenImage: MediaDownloadable {\n public var image: UIImage?\n public var imageURL: URL?\n public var videoURL: URL?\n public var isVideoThumbnail: Bool\n\n public init(imageURL: URL?, isVideoThumbnail: Bool = false, videoURL: URL? = nil) {\n self.imageURL = imageURL\n self.videoURL = videoURL\n self.isVideoThumbnail = isVideoThumbnail\n }\n\n public func loadImageWithCompletionHandler(_ completion: @escaping (UIImage?, NSError?) -> Void) {\n if let image = image {\n completion(image, nil)\n return\n }\n loadImageWithURL(imageURL, completion: completion)\n }\n\n // use any network calls you like\n public func loadImageWithURL(_ url: URL?, completion: @escaping (_ image: UIImage?, _ error: NSError?) -> Void) {\n guard let _url = url else {\n completion(nil, NSError(domain: \"FullScreenImageBrowserDomain\",\n code: -2,\n userInfo: [ NSLocalizedDescriptionKey: \"Image URL not found.\"]))\n return\n }\n let urlRequest = URLRequest(url: _url)\n\n downloader.download(urlRequest) { [weak self] response in\n debugPrint(response.result)\n\n if let remoteImage = response.result.value {\n self?.image = remoteImage\n completion(remoteImage, nil)\n } else {\n completion(nil, NSError(domain: \"FullScreenImageBrowserDomain\",\n code: -1,\n userInfo: [ NSLocalizedDescriptionKey: \"Couldn't load image from remote\"]))\n }\n }\n }\n}\n```\n\n## Folder Structure\n\n```shell\n├── animator\n│ └── FullScreenImageTransitionAnimator.swift\n├── asset\n│ └── FullScreenImageBrowser.bundle\n│ ├── close.png\n│ ├── close@2x.png\n│ └── close@3x.png\n├── core\n│ ├── FullScreenImageBrowser.swift\n│ ├── FullScreenImageBrowserViewModel.swift\n│ ├── MediaDownloadable.swift\n│ ├── MaskImageViewer.swift\n│ ├── SingleImageViewer.swift\n│ └── ZoomableImageView.swift\n└── helper\n ├── SingleImage.swift\n └── UIView+SnapShot.swift\n```\n\n| File | Responsiblity |\n|--------------------------------------|--------------------------------------------------------------------------------------|\n| animator | customised fade in/fade out animations with damping factors |\n| asset | customised static image asset for the full screen image/video browser navigation bar |\n| core/FullScreenImageBrowser | manager class to be responsible for full screen image/video browser |\n| core/FullScreenImageBrowserViewModel | datasource and business logic for full screen image/video browser |\n| core/MediaDownloadable | protocol to define images to be able to asynchronously download |\n| core/MaskImageViewer | `customised` overlay view for full screen image/video browser |\n| core/SingleImageViewer | view controller to be responsible for single image rendering on the full screen |\n| core/ZoomableImageView | view to add support for image to zoom, pin, rotate, and animation |\n\n## Demo\n\n\n
