Run in Xcode 4

```
Hi Everyone,

I just wondering, is there anyone trying to build this project in Xcode4?
I want it supports iOS 6, but right now I haven't succeeded. 
Does anyone able to do that?

If you can do it, please contact me at bozhao.qi@gmail.com

Thank you so much for the help.

Best,
```
