简介
INSPhotoGallery 由 Michał Zaborowski 为 inspace.io 编写。
INSPhotoGallery
INSPhotoGallery 是一个现代风格的相册，用 Swift 编写，适用于 iOS。除了可以处理照片的下载外，它还允许你为图像下载编写自定义逻辑；如果你不喜欢当前的设计，它也允许你创建自定义覆盖层。此外，它支持交互式滚动卡 dismissing、动画缩放展示以及许多其他功能。它受到了 NYTPhotoViewer 的启发。
简单用法
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)
}自定义照片模型
您可以为您的应用程序创建自定义照片模型，该模型可以使用默认的 INSPhoto 替代。默认实现不缓存图像。如果您想使用一些缓存机制或使用某些库来下载图像，比如 HanekeSwift，则必须实现 INSPhotoViewable 协议。
@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"]))
}
}
}CocoaPods
