Promotion UIActivityController on Facebook

I added UIActivityControllerto my project. There seems to be much less help on this topic. The problem I am facing is that the links are spreading on Facebook in a weird way, and not on how they are commonly used on Facebook. To make more sense, photos along with links go to the iOS Photos folder without any changes.

The following is an example image of how they are currently distributed on Facebook:

How they usually spread on Facebook and what I want:

Here is the code I'm using to add a UIActivityController to my project:

UIActivityViewController *objVC = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:titleString, [NSURL URLWithString:urlString], imageTaker, nil] applicationActivities:nil];


[self presentViewController:objVC animated:YES completion:nil];
[objVC setCompletionHandler:^(NSString *activityType, BOOL completed)
 {
     NSLog(@"Activity = %@",activityType);
     NSLog(@"Completed Status = %d",completed);

     if (completed)
     {
         UIAlertView *objalert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Posting was success" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
         [objalert show];
         objalert = nil;
     }else
     {
         UIAlertView *objalert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Posting was not successful" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
         [objalert show];
         objalert = nil;
     }
 }];

In addition, I also get some warnings in the console, which follow below:

Registering unknown app identifier com.apple.mobilemail failed
Unable to find app identifier com.apple.mobilemail
Registering unknown app identifier com.apple.MobileSMS failed
Unable to find app identifier com.apple.MobileSMS
