Game Center LEaderboard Questions

I am in the process of adding Game Center to one of my apps. What I would like to do is set up a leader board per "continent" (North America, South America, Asia, Europe, etc.).

Question 1: If I do this, does game center have the ability to show all results for all leader boards on one leader board? Meaning, I can allow users to see if they are top in their continent, but then also allow them to check their ranking overall. Possible?

Question 2: Since my app is Universal, is there a way to force the standard GC Leader board on the iPad to full screen? I have played around开发者_开发技巧 with the GKLeaderBoardViewController view.bounds and although this does allow me change the size, it still maintains the original border of the default size. Meaning, there is a square box around the middle of the view, but the data is actually expanded like it should be. (I wish I knew how to include pics here) Have also used the modelPresentationStyle but same results with the box around a smaller portion of the screen.

Finally, concerning both questions above, is it just better to create your own custom view? I was hoping to avoid this especially since the newer look from iOS 5 Leader boards are actually very nice.

Thanks in advance for any and all suggestions.

So yes the do allow for one main combined leader board. Just a matter of creating a combined one and adding the others as you see fit.

As for making Game Center full screen on the iPad, no response and luck with searches.
