iosでinstagramを共有するには？

Question

私は図表とキャプション付きの画像を共有する必要がありますが、Instagramでは何も来ません。私は以下のコードをInstagram上で共有するために使用しました。共有のコードに変更はありますか？ Instagramの公式ページもチェックしますが、コードは与えられていません。 https://www.instagram.com/developer/mobile-sharing/iphone-hooks/

次のコードはios10まで動作していますが、ios11ではこれ以上動作しません。

ファイルはドキュメントディレクトリに正常に書き込みましたが、問題はUIDocumentInteractionControllerにありました。ドキュメントディレクトリからファイルを読み込むことはできません。 "com.instagram.photosは" "com.instagram.photo"する必要があります：あなたは間違ったUTIを使用

//MARK: 
    //MARK: share with instagram 
    func shareImageToInstagram(withImagePath imgPath:String,withStrTitle strTitle:String,withView view:UIView,withSender sender:UIButton! = nil) { 
     let instagramURL = URL(string: "instagram://app") 
     if UIApplication.shared.canOpenURL(instagramURL!) { 
      interactionController = UIDocumentInteractionController(url: URL.init(fileURLWithPath: imgPath)) 
      interactionController?.uti = "com.instagram.photos" 
      interactionController?.annotation = NSDictionary.init(dictionaryLiteral: ("InstagramCaption",strTitle)) 
      interactionController?.presentOpenInMenu(from: CGRect.zero, in: view, animated: true) 
      sender.isUserInteractionEnabled = true 
     } 
    } 

    //MARK: 
    //MARK: share with instagram 
    func downloadUserImageFromURL(withImageUrl imgURl : URL,withView view:UIView,withstrTitle strTitle:String,withSender sender:UIButton! = nil){ 

     DispatchQueue.global(qos: .userInitiated).async { 
      do { 
       DispatchQueue.main.async { 
        SINGLETON.startLoadingActivity(view) 
       } 
       let data = try Data.init(contentsOf: imgURl) //make sure your image in this url does exist, otherwise unwrap in a if let check 
       DispatchQueue.main.async { 
        SINGLETON.stopLoadingActivity(view) 
        //create instance of NSFileManager 
        let paths: [Any] = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true) 
        //create an array and store result of our search for the documents directory in it 
        let documentsDirectory: String = paths[0] as? String ?? "" 
        //create NSString object, that holds our exact path to the documents directory 
        let fullPath: String = URL(fileURLWithPath: documentsDirectory).appendingPathComponent("insta.igo").absoluteString 
        //add our image to the path 

        if FileManager.default.fileExists(atPath: fullPath) 
        { 
         do { 
          try FileManager.default.removeItem(at: URL.init(string: fullPath)!) 
         } catch let error as NSError { 
          sender.isUserInteractionEnabled = true 
          print(error.localizedDescription) 
         } 
        } 
        do { 
         try data.write(to: URL.init(string: fullPath)!) 
         self.shareImageToInstagram(withImagePath: fullPath, withStrTitle: strTitle, withView: view,withSender: sender) 

        } catch let error as NSError { 
         sender.isUserInteractionEnabled = true 
         print(error.localizedDescription) 
        } 

       } 
      } 
      catch{ 
       DispatchQueue.main.async { 
        SINGLETON.stopLoadingActivity(view) 
       } 
      } 
     } 
    }

また、URL instagramをplistにKey LSApplicationQueriesSchemesに追加することを忘れないでください。

Here Instagram（メソッド- (void)send）に共有する例があります。そこから
メインコード： のObjective-C：

// make a path into documents 
    NSString* homePath = [self _getpathToDocuments]; 
    NSString* basePath = @"integration/instagram"; 
    NSString* tmpFileName; 
    if ([self _isInstagramOnly]) { 
     tmpFileName = @"jumpto.igo"; 
    } else { 
     tmpFileName = @"jumpto.ig"; 
    } 

    NSString* dirPath = [NSString stringWithFormat:@"%@/%@", homePath, basePath]; 
    NSString* docPath = [NSString stringWithFormat:@"%@/%@", dirPath, tmpFileName]; 

    [[NSFileManager defaultManager] removeItemAtPath:docPath error:nil]; 
    if ([[NSFileManager defaultManager] createDirectoryAtPath:dirPath withIntermediateDirectories:YES attributes:nil error:nil]) { 
     UIImage* tmpImg = [self _imageForSharing]; 

     if([self _needResizeImage]){ 
      tmpImg = [self _resizeImage:tmpImg]; 
     } 

     NSData* imgData = [self generateImageData:tmpImg]; 
     [[NSFileManager defaultManager] createFileAtPath:docPath contents:imgData attributes:nil]; 
     NSURL* url = [NSURL fileURLWithPath:docPath isDirectory:NO ]; 

     NSString *UTI = nil; 
     if ([self _isInstagramOnly]) { 
      UTI = @"com.instagram.exclusivegram"; 
     } else { 
      UTI = @"com.instagram.photo"; 
     } 

     NSString *captionString = @"Caption message"; 

     UIDocumentInteractionController* dic = [UIDocumentInteractionController interactionControllerWithURL:documentFileURL]; 
     dic.UTI = UTI; 
     dic.annotation = @{@"InstagramCaption" : captionString}; 
     dic.delegate = self; 

     [self presentOpenInMenuFromRect:[self _getButtonRect] inView:self.view animated:YES]; 
    }
