Facebook分享在iOS上显示空白图像，但在桌面上工作正常

Question

我正在使用以下页面中的AddThis：http://www.douglasstratton.com/Beaches/Amnesia/flypage.tpl.html

从桌面共享时，图像共享正常，但在iOS上共享时，Facebook墙上的图像为空白。

还有其他人有这个问题吗？

You can share with this code.Only import #import <FacebookSDK/FacebookSDK.h>:-
  // Put together the dialog parameters
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   APP_NAME, @"name",
                                   self.strSerialName , @"caption",
                                   modelObject.strChapterDescription, @"description",
                                   @"", @"link",
                                   modelObject.strChapterImage, @"picture",
                                   nil];
    // Show the feed dialog
    [FBWebDialogs presentFeedDialogModallyWithSession:nil

                                                      // See: https://developers.facebook.com/docs/ios/errors
