使用 SSZipArchive 解压缩文件而不提取文件的内容

Question

我正在使用 SSZipArchive 提取文件的内容，该文件是我从 Internet 下载并保存在 Documents 中的。我下载的资源是zip文件，下载成功后会解压

@IBAction func downloadData(sender: UIButton)
{       if let myAudioDataFromUrl = NSData(contentsOfURL: audioUrl){
                // after downloading your data you need to save it to your destination url
                if myAudioDataFromUrl.writeToURL(destinationUrl, atomically: true) {
                    print("file saved")
                    printTimestamp()
                    let folderName = "Aspire  Brochure"//audioUrl.lastPathComponent!.stringByReplacingOccurrencesOfString(".zip", withString: "")
                    let destination = documentsUrl.URLByAppendingPathComponent(folderName)
                    let fileManager = NSFileManager.defaultManager()
                    print("This is the folderName \(destinationUrl)")
                    print("This is the destination \(destination)")
                    let success = fileManager.fileExistsAtPath(destination.absoluteString) as Bool
                    if success == false {
                        do {
                            print("it is here")
                            try! fileManager.createDirectoryAtPath(destination.absoluteString.stringByReplacingOccurrencesOfString("file://", withString: ""), withIntermediateDirectories: true, attributes: nil)
                            print("it hascome here  ")
                        }
                    }
                 //   let success = fileManager.fileExistsAtPath(destPath) as Bool
                    print("trying to unzip the file")

                    //let fileManager = NSFileManager.defaultManager()
                    let checkFile = NSFileManager.defaultManager().fileExistsAtPath(destination.absoluteString.stringByReplacingOccurrencesOfString("file://", withString: ""))
                    print("this is the check value response \(checkFile)")
                    var tmp = SSZipArchive.unzipFileAtPath(destinationUrl.absoluteString, toDestination: destination.absoluteString )
                    //var tmp = SSZipArchive.unzipFileAtPath(destination.absoluteString.stringByReplacingOccurrencesOfString("file://", withString: ""), toDestination: destination.absoluteString )
                    print("unzipped the file \(tmp)")

                    } else {
                        print("error saving file")
                    }
                }
            }

正在创建文件，但没有提取任何内容。

运行今天我花了几个小时才弄明白。 SSZipArchive returns false 当找不到 zip 文件时。这可能是因为您返回的 url 是一个 [NSURL absoluteString];，它的开头有 file://。只需在 url 上调用 [NSURL path]; 就可以了
