iPhone: Group by month - Core Data
<p>I store dates in a core data entity
attribute, I then display the date in
the table cells. I want to group all
the cells according to months and only
display the relevant dates in the
correct sections.</p>

<p>I'm using sectionNameKeyPath of the
NSFetchedResultsController, but I need
to only use the month in the date to
group. How can I achieve this? Would I
need to create a new attribute and
store just the month as a string or
can I use NSPredicate?</p>

<p>Please can anyone let me know if they
have done this or give me some
examples.</p>

<p>Thanks</p>
