INSPhotoGallery was written by Michał Zaborowski for inspace.io
INSPhotoGallery is a modern looking photo gallery written in Swift for iOS. INSPhotoGallery can handle downloading of photos but in addition to that it allows you to make custom logic for downloading images, also it allows you to make custom overlay if you won't like current design. In addition it support interactive flick to dismiss, animated zooming presentation and many more. It was inspired by NYTPhotoViewer.
lazy var photos: [INSPhotoViewable] = {
return [
INSPhoto(imageURL: NSURL(string: "http://inspace.io/assets/portfolio/thumb/13-3f15416ddd11d38619289335fafd498d.jpg"), thumbnailImage: UIImage(named: "thumbnailImage")!),
INSPhoto(imageURL: NSURL(string: "http://inspace.io/assets/portfolio/thumb/13-3f15416ddd11d38619289335fafd498d.jpg"), thumbnailImage: UIImage(named: "thumbnailImage")!),
INSPhoto(image: UIImage(named: "fullSizeImage")!, thumbnailImage: UIImage(named: "thumbnailImage")!),
]
}()func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
let cell = collectionView.cellForItemAtIndexPath(indexPath) as! ExampleCollectionViewCell
let currentPhoto = photos[indexPath.row]
let galleryPreview = INSPhotosViewController<INSPhoto>(photos: photos, initialPhoto: currentPhoto, referenceView: cell)
galleryPreview.referenceViewForPhotoWhenDismissingHandler = { [weak self] photo in
if let index = self?.photos.indexOf({$0 === photo}) {
let indexPath = NSIndexPath(forItem: index, inSection: 0)
return collectionView.cellForItemAtIndexPath(indexPath) as? ExampleCollectionViewCell
}
return nil
}
presentViewController(galleryPreview, animated: true, completion: nil)
}You are able to create your custom photo model which can be use instead default INSPhoto. Default implementation don't cache images. If you would like to use some caching mechanism or use some library for downloading images for example HanekeSwift use must implement INSPhotoViewable protocol.
@objc public protocol INSPhotoViewable: class {
var image: UIImage? { get }
var thumbnailImage: UIImage? { get }
func loadImageWithCompletionHandler(completion: (image: UIImage?, error: NSError?) -> ())
func loadThumbnailImageWithCompletionHandler(completion: (image: UIImage?, error: NSError?) -> ())
var attributedTitle: NSAttributedString? { get }
}class CustomPhotoModel: NSObject, INSPhotoViewable {
var image: UIImage?
var thumbnailImage: UIImage?
var imageURL: NSURL?
var thumbnailImageURL: NSURL?
func loadImageWithCompletionHandler(completion: (image: UIImage?, error: NSError?) -> ()) {
if let url = imageURL {
Shared.imageCache.fetch(URL: url).onSuccess({ image in
completion(image: image, error: nil)
}).onFailure({ error in
completion(image: nil, error: error)
})
} else {
completion(image: nil, error: NSError(domain: "PhotoDomain", code: -1, userInfo: [ NSLocalizedDescriptionKey: "Couldn't load image"]))
}
}
}Add the following to your Podfile and run $ pod install.
