从swift文件目录中获取图像

说我正在使用这个代码来保存图像到文件directroy let nsDocumentDirectory = NSSearchPathDirectory.DocumentDirectory let nsUserDomainMask = NSSearchPathDomainMask.UserDomainMask if let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true) { if paths.count > 0 { if let dirPath = paths[0] as? String { let readPath = dirPath.stringByAppendingPathComponent("Image.png") let image = UIImage(named: readPath) let writePath = dirPath.stringByAppendingPathComponent("Image2.png") UIImagePNGRepresentation(image).writeToFile(writePath, atomically: true) } } } 我将如何回顾它？ 请记住，在iOS8中，确切的path经常变化
