问题描述

我需要执行以下操作-

我还有另一个应用程序，其中我将以zip格式导出用户的config(.txt)和contact(.vcf).

I have another app in which i will export the users config(.txt) and contacts(.vcf) in a zip format.

在第二个应用程序中，我有一个共享扩展名以获取导出的zip，在共享扩展名中，我需要提取zip文件并获取txt和vcf文件，然后将它们上传到解析服务器.

In the second app i have a share extension to get the exported zip and in the share extension, i need to extract the zip file and get both the txt and vcf files and then upload them to a parse server.

在共享扩展名中打开导出的zip之前，我已经做完了.但我无法提取压缩文件.我无法在互联网上找到答案.

I have done till opening the exported zip in the share extension. but i could not get the zip extracted.I couldn't get the answer in internet.

这是我的ShareViewController

import UIKit
import Social
import Parse
import MobileCoreServices
import SSZipArchive

class ShareViewController: SLComposeServiceViewController {

    var requird_data : NSData!
    var path : URL!

    override func viewDidLoad() {
        super.viewDidLoad()
        //Parse.setApplicationId("cGFyc2UtYXBwLXdob3N1cA==", clientKey: "")
        initUI()
        getURL()
        textView.delegate = self
        textView.keyboardType = .numberPad
    }

//    override func viewWillAppear(_ animated: Bool) {
//        super.viewWillAppear(true)
//
//    }

    func initUI()
    {

        navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
        title = "upup"

        navigationController?.navigationBar.tintColor = .white
        navigationController?.navigationBar.backgroundColor = UIColor(red:0.97, green:0.44, blue:0.12, alpha:1.00)
        placeholder = "Please enter your Phone number"
    }

    private func getURL() {
        let extensionItem = extensionContext?.inputItems.first as! NSExtensionItem
        let itemProvider = extensionItem.attachments?.first as! NSItemProvider
        let zip_type = String(kUTTypeZipArchive)
        if itemProvider.hasItemConformingToTypeIdentifier(zip_type) {
            itemProvider.loadItem(forTypeIdentifier: zip_type, options: nil, completionHandler: { (item, error) -> Void in
                guard let url = item as? NSURL else { return }
                print("\(item.debugDescription)")
                OperationQueue.main.addOperation {
                    self.path = url as URL
                    SSZipArchive.unzipFile(atPath: url.path!, toDestination: url.path!)
                }
            })
        } else {
            print("error")
        }
    }

    override func isContentValid() -> Bool {
        // Do validation of contentText and/or NSExtensionContext attachments here
        return true
    }

    override func didSelectPost() {
        // This is called after the user selects Post. Do the upload of contentText and/or NSExtensionContext attachments.

        // Inform the host that we're done, so it un-blocks its UI. Note: Alternatively you could call super's -didSelectPost, which will similarly complete the extension context.
        self.extensionContext!.completeRequest(returningItems: [], completionHandler: nil)
    }

    override func configurationItems() -> [Any]! {
        // To add configuration options via table cells at the bottom of the sheet, return an array of SLComposeSheetConfigurationItem here.
        return []
    }

    override func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool
    {
        let length = ((textView.text)?.characters.count)! + text.characters.count - range.length
        let allowedset : CharacterSet = CharacterSet(charactersIn: "0123456789+").inverted as CharacterSet
        let filtered  = (text.components(separatedBy: allowedset)).joined(separator: "")

        return (length<17) && (text == filtered)
    }

}

我使用SSZipAchive提取文件.链接: https://github.com/ZipArchive/ZipArchive

我在Xcode 9 beta 1中运行了该应用程序.我使用了模拟器中新的Files应用程序来共享zip.以下是我的共享扩展信息Plist

I ran the application in the Xcode 9 beta 1. I used the new Files app from simulator to share the zip.Below is my Share Extensions Info.Plist

我是分享扩展程序的新手，所以我对此不太了解.上面的所有代码都是来自以下教程的点点滴滴和一些谷歌搜索.

I am newbie to share extension so i don't know much about it. All the code above are from bits and pieces from the following tutorials and a little googling.

1. https://www.appcoda.com/ios8-share-extension -swift/

2. https://hackernoon. com/how-to-to-build-an-ios-share-extension-in-swift-4a2019935b2e

请指导我.我用的是swift 3.
