Question

I have a Core Data based application which is built around one main entity. There are several other entities which are connected to it, one of which is an Entity called “Notes”.

This Notes entity has a Date (NSDate), a Description (NSString), and one other attribute. This attribute is to have 4 possible options, of which each entity will have at least 1 and possibly all 4.

I was thinking that when a Note is being created, there could be a Segmented Controller with the 4 possible options. (Is it even possible to select multiple buttons here?)

I further want to be able to sort all of these notes by this option. That is, to create a fetch request that returns only the Notes that had Option 3 selected, for example. (Even if they also had Option 2, or even all 4 options selected.)

Any suggestions on what the best way to implement this is?

Thanks.

Answer 1

First, instead of trying to use one attribute to collect four possible options, I would use four separate boolean attributes. This will also allow you to filter your fetch requests very easily.

To configure each boolean, I would use a UIButton or UISwitch. The UISegmentedControl does not support multiple selection.
