Swift实现文件压缩和解压示例代码

@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!)")  } }

@IBAction func unZipAction(_ sender: UIButton) {  guard let zipPath = self.zipPath else {   return  }  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 tempZipPath() -> String {  var path = NSSearchPathForDirectoriesInDomains(.cachesDirectory, .userDomainMask, true)[0]  path += "//(UUID().uuidString).zip"  return path } 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 }
