I'm having a hard time figuring out how to construct a query. The
objects involved are:
Entry
- has many tags
Tag
- name (string)
- value (string)
I want to construct searches such as:
- find all entries that have a the tag named "priority" with the
value "1".
I can use [NSPredicate predicateWithFormat:@"ANY tags.name = %@",
tag.name] to find all entries that have a particular tag... but I
don't know how to also figure in the value.
I don't need this predicate to work with a database, these queries are
all just being run in memory, with my own custom model objects (not
using Core Data). If there is no way to do this in a format string, is
there some way to do it by directly constructing a predicate object?
Thanks,
Jesse
