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.
压缩
@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!)")
}
}
</div>
#解压
@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)")
}
}
</div>
压缩和解压路径:
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
}
</div>
