I am pretty new to programming any sort of device and am on a steep learning curve, so please forgive me if this doesnt make too much sense or the code in the question is awful - we all ave to start somewhere, and beleive me, i have read and read and read!
I am creating a table from a plist which is an array of dictionarys - i need it in this format as later i wish to be able to change some of the values and write back to the relevant plist 'key'. I am hoping that someone will be able to look at this and give me some pointers as to how to...
Obviously i'm a long way from sorting all this out - the code itself is a bit of a 'dogs-dinner' at the moment as i have been trying so many different things without much success, so if you see something you dont like please let me know!
I have been trying to read up on all the relevant sections such as UILocalizedIndexedCollation and sortedArrayUsingDescriptors but i guess my brain just isnt up to it...
Any and all advice (except 'give it up you're not bright enough for this' as i never give up on anything i start!) would be much appreciated!
(there are lots of unused variables synthesized at the beginning - i have taken the relevant code out in order to simplify what i have posted here, the code compiles with no problems, and works given me the following result: a table with 27 letters indexed on the right hand side of which only AJ work (which correlates to the number of sections produced in the table - there are only section AJ. The contents of the cells are exactly what i want.)

Any advice would be greatly appreciated - at the moment i have been working on this for about a week with no success and am close to just giving up, which i really dont want to do!
If the worst come to the worst and i cant get this done would ayone be willing to write the functionality in for me, for a small fee of course!!
Cheers, and heres hoping...
