ios - Tab bar issue for iPad app -

i'd display looks vertical tab bar @ left side in, example, twitter app ipad:

1. is uisplitviewcontroller uitabbar within left side?
2. is tab bar vertical orientation (if possible, couldn't find such property in uitabbar class...)?
3. is custom tabbar-like control?
4. i've read posts dealing (for instance, ios vertical tab bar), written time ago, issue remain same?

thanks!

there custom tabbar control available . think this fit requirements.

hope you.

all best !!!
