Content system survey

This iPhone application is for business that fetches content from the server in the form of pdf and images. Users can add annotations on extracted PDF and the updated PDF is sent back to the server. Users login and after that app fetches data for that user. Each user has its own data which is handled by admin on the server. A User can take a survey which gets updated to the same server.

This app works primarily in an offline mode (uses XML or local data for presentation). It automatically checks and updates local data whenever online and displays data accordingly.
