Folks,
I'm sure this qualifies as a "newbie" question, but I'll ask anyway. I
was looking at the videos of the Core Data tutorial and I noticed that
none of the tabular items being bound were anything but strings.
I have a situation where I have an entity that has a Date column and an
Int32 column. I set up the bindings using Core Data, set up a controller
- everything works fine when I set the data types to string. However,
when I set the data types in the model to what they should be, I keep
getting errors from the GUI indicating that it was an inappropriate type
(e.g. "string" when expecting an NSCFDate etc).
I have tried dragging a datepicker cell into the cell in the tableview,
but that doesn't quite do the trick. Also, I can't figure out how to
deal with the cell that I want to allow me to enter integers. I type in,
say, "200", then hit tab to commit that cell, and then I see the error
in the Console log showing that it got the string "200" instead of the
number 200.
I'm sure there's a simple solution to this - can anyone tell me what
step I'm missing to get my table to allow me to pick dates (hopefully
from a pop-up calendar, or at least default to today's date) and enter
numbers directly into the table?
Thanks,
Kevin
