Do you know open source alternatives for UISplitViewController?

I think the fixed width of RootViewController in UISplitViewController is quite a limitation: for some cases 320px is way too much space to wast开发者_开发问答e, while DetailedView could use more space efficiently to provide better UX. (a good example of "some cases" is Living Social iPad app)

So far I've found MGSplitViewController. Do you know of any other open source solutions extending UISplitViewController functionality?

I know that using alternatives are a bit against "the HIG", but did you hear of any app using alternative solutions was rejected?

cUISplitViewController is a Good one.

Here's another: APSplitViewController

And another: IntelligentSplitViewController (Dangerous in my opinion)

And FYI, using alternate solutions are not discouraged in any way by Apple's HIG. If the alternate solution is violating the HIG or other standard guidelines e.g. use of private APIs etc, then you'll face problems.

p.s. I'm looking for a solution that works like UISplitViewController, but with UITabBar. UISplitViewController, MGSplitViewController both provide excellent controls but they both don't work with UITabBar. IntelligentSplitViewController was/is the perfect candidate, but it accesses private members :^(.
