IOS Facebook SDK如何分享圖片，鏈接，文字？

Question

我在ios應用程序中使用了最后一個facebook sdk，並且嘗試共享包含說明和鏈接的圖像。 我努力了

[FBDialogs presentShareDialogWithLink] 

但我無法在共享結果中看到我的描述文本。 我努力了

[FBDialogs presentShareDialogWithPhotoParams] 

但是FBPhotoParams的描述字段為“ onlyread”，並且我無法添加任何文本。 所以我放棄了各種fbdialogs，我嘗試了另一種應用程序：

if ([[FBSession activeSession] isOpen]) {
    /*
     * if the current session has no publish permission we need to reauthorize
     */
    if ([[[FBSession activeSession] permissions]indexOfObject:@"publish_actions"] == NSNotFound) {

        [[FBSession activeSession] requestNewPublishPermissions:[NSArray arrayWithObject:@"publish_actions"] defaultAudience:FBSessionDefaultAudienceFriends
                                              completionHandler:^(FBSession *session,NSError *error){
                                                  [self share];
                                              }];

    }else{
        [self share];
    }
}else{
    /*
     * open a new session with publish permission
     */

    [FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
                                       defaultAudience:FBSessionDefaultAudienceOnlyMe
                                          allowLoginUI:YES
                                     completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
                                         if (!error && status == FBSessionStateOpen) {
                                             [self share];
                                         }else{
                                             NSLog(@"error");
                                         }
                                     }];



}

現在這個方法不起作用，並返回一個錯誤：

"OAuth \"Facebook Platform\" \"insufficient_scope\" \"(#200) The user hasn't authorized the application to perform this action\"";

我沒有共享權限，但用戶從未看到權限對話框...也許我必須將我的應用程序提交給Facebook，以獲取我的Facebook應用程序的“一般” ublish_actions權限？ 它只是一個鏈接，我不想發送構建，等待批准，ecc ..現在分享圖像和文本的鏈接真的很復雜？ 我想會有一個更簡單的解決方案......我該怎么辦？

用這個，

NSMutableDictionary *parameter = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   name, @"name",
                                   author, @"caption",
                                   linkShare, @"link",
                                   userImage, @"picture",
                                   nil];

[FBWebDialogs presentFeedDialogModallyWithSession:nil
                                       parameters:parameter
                                          handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                                              if (error)
                                              {
                                                  NSLog(@"Error publishing story: %@", error.description);
                                              }
                                              else
                                              {
                                                  if (result == FBWebDialogResultDialogNotCompleted)

                                                  }
                                                  else
