Help each other build a pdf reader-viewer?

Does anybody that know a little bit about xcoding want to build a pdf reader-viewer together? I have found a good startingpoint 开发者_如何学Pythonwith a reader in a uiwebview. What needs to be done is some navigation to step between the pdf pages. I dont know much xcoding since I build most in uiwebviews, but I know a bit about designing and user navigation. So if you think it would be fun let me know.

Whatever you made till now, just upload it to any hosted SVN or GIT sites, and open source the code.
