ios - App for signing PDF's and categorizing them on a webserver -

i've been researching best way implement application brother's business, , have been pretty stumped in terms of how structure application. application run on ipad 2's deployed in field, without readily available network access (due spotty cell coverage in area).

here abstract on needs do:

1) load template pdf file (its contract sign cable service) has editable fields, such as:

a) name b) street address c) dates

2) able collect drawn signature (very similar credit card app, such square, etc), overlaid onto pdf.

3) save pdf, containing drawn signature , other edited fields, new file. then, upload backend server, using name of individual , date/time meta data sorting specific folders.

without third aspect, employee have spend 30 minutes 2 hours day categorizing of app submissions, step number 3 pretty important aspect development, though of work outside realm of objective c. still, need send pdf file off information attached can...

i'd appreciate guidance related best course of action in developing this. there open source applications guys know of can reference to? have searched apple's developer member center , google no avail.

how implement itext here? best option?? digital signatures opposed drawn ui kit...

sounds should have web service database storing meta information , path generated pdf signature , other entries.

your app generate pdf, make web service call , insert information such client's name, date/time, whatever else want, , name or path of pdf file. pdf file subsequently uploaded designated location unique file name prevent overwriting pdf. formulate name of file off of corresponding key/id of record in database or use guid filename , measure concatenate epoch timestamp when file generated. both approaches should guarantee filename uniqueness. possible file name scheme device uuid+epoch timestamp, many options available.
