That seems to be a roundabout way to get a date 30 days ago from now,
but in the end it seems ok. (Except that the date is going to be
fixed in time when the smart group is created, unless you take other
steps to march the predicate forward, so if I have your app running
for 60 days, I'll get 60 days with of items, not 30.
When I print a description of this predicate to the console, I get
something like this:
"dateAdded" > CAST(151788356.228000, "NSDate")
That isn't alarming...
The problem is that the fetch request usually (but not always)
fails, and this is the cause that gets logged to the console:
[NSCFDate length]: selector not recognized
It works when I plug it into my testbed application. I didn't test it
exhaustively. Your best bet is going to be to stop in the debugger in
the failing case, look at the stack, and work backwards from there.
