Swift 编写的网络图像库：Skeets

Skeets 是网络图像库，可以通过 HTTP 来匹配，缓存和显示图片。Skeets 是使用 Swift 编写的，使用 SwiftHTTP 构建。

//create a imageView  let imageView = UIImageView(frame: CGRectMake(0, 60, 200, 200))  self.view.addSubview(imageView)    //set the cache directory. Only have to do this once since `sharedManager` is a singleton  let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)  ImageManager.sharedManager.cache.diskDirectory = "\(paths[0])/ImageCache"  ImageManager.sharedManager.cache.cleanDisk()    //fetch the image  ImageManager.sharedManager.fetch("http://vluxe.io/assets/images/logo.png",      progress: { (status: Double) in          println("updating some UI for this: \(status)") //useful if you have some kind of progress dialog as the image loads      },success: { (data: NSData) in          println("got an image!")          imageView.image = UIImage(data: data) //set the image data      }, failure: { (error: NSError) in          println("failed to get an image: \(error)")  })

特性

• 多级缓存，内存和硬盘缓存

• 非阻塞 IO，所有 HTTP 和硬盘 IO 都在后台运行

• 简单的一个方法就可以加载一个远程图片

• 健壮，快速和可定制的缓存

• 几百行简单简洁代码库

• 处理冗余图像请求，一个请求多个查询
