从自定义 SwiftUI 视图中关闭共享扩展

如何解决从自定义 SwiftUI 视图中关闭共享扩展

我正在使用来自主要目标的自定义 SwiftUI 视图来从共享扩展的 ShareViewController 共享文档。在浏览三个视图后使用导航链接并共享文档。文档上传没有任何问题，但我不知道如何在上传完成后关闭视图。

这是导航的样子

ShareViewController(SLComposeServiceViewController) -> PropertyListView -> UnitListView -> UploadView

didPost 看起来像这样

override func didSelectPost() {
    print("In Did Post")
    if let item = self.extensionContext?.inputItems[0] as? NSExtensionItem{
        print("Item \(item)")
        print(item.attachments)
        print(item.attachments![0])
        let itemProvider = item.attachments![0]
        if itemProvider.hasItemConformingToTypeIdentifier("com.adobe.pdf"){
            itemProvider.loadItem(forTypeIdentifier: "com.adobe.pdf",options: nil) { (item,error) in
                if error != nil{
                    print(error!.localizedDescription)
                }else{
                    if let url = item as? URL{
                        print(url)
                        dispatchQueue.main.async{
                            //saving to user defaults
                            let dict: [String : Any] = ["dcument" :  url.absoluteString,"name" : self.contentText.isEmpty ? url.lastPathComponent : self.contentText!]
                            let savedata =  UserDefaults.init(suiteName:"group.in.pixbit.hijricalendar")
                            savedata?.set(dict,forKey: "sharedDocument")
                            savedata?.synchronize()
                        //loading swiftui view
                            let swiftuiView = NavigationView{PropertyListView()}
                            let vc = UIHostingController(rootView: swiftuiView)
                            let newView = vc
                            self.view.window?.rootViewController = newView
                            self.view.window?.makeKeyAndVisible()

                        }
                    }
                }
            }
        }
    }
}

解决方法

您需要在视图控制器的 completeRequest(returningItems:completionHandler:) 上调用 extensionContext。

这是我的一个应用的代码片段：

  override func didSelectPost() {
    let artifact = Artifact(title: self.contentText,author: self.metaAuthor,url: url?.absoluteString ?? metaUrl ?? "",imageUrl: metaImage,siteName: self.siteName,dateAdded: Date(),excerpt: metaDescription,notes: "",tags: nil)
    self.artifactRepository?.addArtifact(artifact)
    
    self.extensionContext?.completeRequest(returningItems: [],completionHandler:nil)
  }
