By formatting the dates as MMDD and keeping them in strings you can use
simple string comparison to sort, compare and filter. They are also very
easy to format for display purposes. If you want to go standard then use the
ISO 8601 date format. It's -MM-DD. See
NSDate conceptually store time relative to Jan 1, 2001, GMT.
When it is formatted for display, it uses the current time zone (or more
correctly, the NSDateFormatter uses whatever time zone has been specified,
or the current system time zone). If your time zone changes (such as by

Luke helped me with this a little bit, but, after experimenting, it seams
there is more to it.
I guess there is still something I do not understand about this. Yes, I can
set a huge number of rows. But I want them to be grouped into sections.
However, UITableView wants to know exactly how many
of sections but it isn't easy to calculate the size of said
sections. What are you really trying to do?

I don't see an example of how you are creating cells in your first post. But
in case you were using the same string for the reuse identifier then when
the cell is loaded the second time it will not switch to a different style.
Because whatever cell was cashed the first time it will be reused.

The way I understand what you want to do is this:

Instead of target-action you could set up an iboutleted property, connect

It's generally a bad idea to have two objects each retain the other. It
