用到的第三方框架：
Alamofire
SSZipArchive
下载方法代码：
func downLoadFile(url: String, saveFileName: String, pathExtension: String) {
let destination: DownloadRequest.DownloadFileDestination = { _, _ in
var documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
documentsURL.appendPathComponent(saveFileName + "." + pathExtension)
return (documentsURL, [.removePreviousFile, .createIntermediateDirectories])
}
Alamofire.download(url, to: destination).response { response in
if response.error == nil {
guard let desUrl = response.destinationURL else {return}
var path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
path += "/\(saveFileName)/"
let pathURL = URL(fileURLWithPath: path)
do {
try FileManager.default.createDirectory(at: pathURL, withIntermediateDirectories: true, attributes: nil)
DSLog("解压路径：\(pathURL.path)")
} catch let err {
DSLog(err.localizedDescription)
}
let urlStr = desUrl.absoluteString
DSLog("源文件路径：\(urlStr)")
let done = SSZipArchive.unzipFile(atPath: urlStr.replacingOccurrences(of: "file://", with: ""), toDestination: path)//解压,两个参数一个是文件的路径,一个是解压后的位置
if done {
DSLog("解压成功")
//清除压缩包
}else{
DSLog("解压失败")
}
}
}
}
调用方法代码：
downLoadFile(url: "下载链接", saveFileName: "自定义名称", pathExtension: "后缀")
