在 Twitter 中分享链接与预览 iOS？

Question

我有一个应用程序，我在其中使用 Uiactivityviewcontroller 共享到 twitter 的链接。它只在我的 TL 中显示 twitter 中的文本和链接。我希望它像在 Facebook 中一样显示，并从链接中提取图像。我就是这样的

    NSURL *shareUrl = [NSURL URLWithString:@“http://dhdhdh”];
  NSString* someText = @“fdfdfd”;

  UISimpleTextPrintFormatter *printData = [[UISimpleTextPrintFormatter alloc]
                                                 initWithText:@"http://dhdhdh"];

  NSArray* dataToShare = @[someText,shareUrl,printData];  // ...or whatever pieces of data you want to share.
  NSArray *appActivities = [NSArray arrayWithObjects:[[UrlActivity alloc] init], nil];
  UIActivityViewController* activityViewController =
        [[UIActivityViewController alloc] initWithActivityItems:dataToShare
                                          applicationActivities:appActivities];
          activityViewController.excludedActivityTypes=@[UIActivityTypeAddToReadingList,UIActivityTypeAirDrop,UIActivityTypePrint,UIActivityTypeAssignToContact];
        // activityViewController.


        [self.navigationController presentViewController:activityViewController animated:YES completion:nil];

有人可以帮我解决这个问题吗？
