So I think you have to remove the stuff at the end of the URL. Before:
[fbSheetOBJ addURL:[NSURL URLWithString:@"https://itunes.apple.com/us/app/hibali/id712909255?ls=1&mt=8"]];
After:
[fbSheetOBJ addURL:[NSURL URLWithString:@"https://itunes.apple.com/us/app/hibali/id712909255"]];
That should do the trick. Let me know. Cheers.
