I need the code for an iphone application where the application does the following:
1. when first starting to use the application, the user needs to initialize the application by entering a date.
2. once the application is initialized the user can take photo using the application just like the camera function on iphone but photo taken will have a display of the time passed since the date. For example 2Y3M4D (2 years 3months and 4 days
3. the user can also pick an image from the photo album and time stamp the image by entering another date (has to be on or after the date entered in 1). the application will save a copy of the image chosen with a display of the time passed between the two dates
