我正在使用SSZipArchive从网址(http://www.colorado.edu/conflict/peace/download/peace.zip)解压缩文件。为此,我使用的功能是:
SSZipArchive.unzipFile(atPath: path, toDestination: documentsPath, progressHandler: {
SSZipArchive
从Url中提取文件? 答案 0 :(得分:0)
如果不从网址下载文件,则无法直接解压缩 这就是我这样做的方式,
func downLoad() {
let url : String = "http://www.colorado.edu/conflict/peace/download/peace.zip"
var localPath: NSURL?
Alamofire.download(.GET,url,
destination: { (temporaryURL, response) in
let directoryURL = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0]
let pathComponent = response.suggestedFilename
localPath = directoryURL.URLByAppendingPathComponent(pathComponent!)
return localPath!
})
.response { (request, response, _, error) in
SwiftEventBus.post("DownloadedSuccessfully", sender: localPath!)
}
}
下载内容后,将其解压缩到您想要的位置。
SwiftEventBus.onMainThread(self, name:"DownloadedSuccessfully")
{
result in
let resultStatus = result.object as! NSURL
guard let zipPath: String = resultStatus.path! as String else {
return
}
guard let unZipPath = unzipPath() else {
return
}
let success = SSZipArchive.unzipFileAtPath(zipPath, toDestination: unZipPath)
print(unZipPath)
if !success {
return
}
}
我解压缩文件并将其存储在文档目录
中func unzipPath() -> String? {
let path = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let url = NSURL(fileURLWithPath: path)
do {
try NSFileManager.defaultManager().createDirectoryAtURL(url, withIntermediateDirectories: true, attributes: nil)
} catch {
return nil
}
if let path = url.path {
return path
}
return nil
}
从那里您可以访问该文件的数据。在这里,我使用了第三方框架Alamofire和swiftEventBus。希望这对你有用。
