Swift实现文件压缩和解压示例代码

项目中有时候需要文件下载解压,项目中选择了ZipArchive,实际使用也比较简单,直接调用解压和压缩方法即可.

@IBAction func zipAction(_ sender: UIButton) {
  let imageDataPath = Bundle.main.bundleURL.appendingPathComponent("FlyElephant").path
 
  zipPath = tempZipPath()
 
  let success = SSZipArchive.createZipFile(atPath: zipPath!, withContentsOfDirectory: imageDataPath)
  if success {
   print("压缩成功---\(zipPath!)")
  }
 }

  guard let unzipPath = tempUnzipPath() else {
   return
  }
 
  let success = SSZipArchive.unzipFile(atPath: zipPath, toDestination: unzipPath)
  if !success {
   return
  }
  print("解压成功---\(unzipPath)")
  var items: [String]
  do {
   items = try FileManager.default.contentsOfDirectory(atPath: unzipPath)
  } catch {
   return
  }
 
  for (index, item) in items.enumerated() {
   print("\(index)--文件名称---\(item)")
  }
 }

 func tempUnzipPath() -> String? {
  var path = NSSearchPathForDirectoriesInDomains(.cachesDirectory, .userDomainMask, true)[0]
  path += "/\(UUID().uuidString)"
  let url = URL(fileURLWithPath: path)
 
  do {
   try FileManager.default.createDirectory(at: url, withIntermediateDirectories: true, attributes: nil)
  } catch {
   return nil
  }
 
 
  return url.path
 }
