Hi,
First off, hi, my name is Sam, I'm a student (yes, I know I'm
posting here, sorry...), and I've been just getting into Cocoa
programming in the past few months after starting out first in Java
and then in Cocoa-Java. Terribly for me my college does not teach
Mac programming, so I'm having to for most part go it alone in terms
of learning. (If you have any good arguments for why they should
start teaching it, could you please send them to me and I'll forward
them along? (-: )
Anyway, here's my issue: I've created a four-column table, bound
values to to cells in it (the left one is an image; the other three
are text); and then decided I'd actually like to use a date formatter
for the far right column. I'm assuming that means that I need to
change the bound values for that column to type "NSDate." I haven't
done that yet, but what I have done is drag an NSDateFormatter from
the IB palette to the table column. Problem is, when I go in to try
to choose the format, it won't let me -- under the "Formatter" view
in the inspector, the default is " %m%d%y " (without the quotation
marks). If I try to select something different in the formatter
table, it will flash on that option very briefly before jumping back
to the default. Same thing with the "Custom Format" text field: If
I click away from the text field for even an instant, it will go back
to the default. It's almost like the formatter is bound to the
default, but I don't see how that can be..... I've tried unbinding
that column to see if that might be the problem, but it did not fix
the problem. One other odd thing I noticed: When I was dragging the
date formatter on to the my table, the outlines for the table columns
were incorrect (off by at least 60px), and IB only recognized three
(as opposed to four) columns as possible drop locations. I suppose
the second oddity is because you can't use a date formatter on an
image, but still, the drop zones seemed way off.
The table was working fine before I added the date formatter.
I've Googled, etc. for this issue and can't find any mention of it.
Do you know what could be causing it, and what a possible work-around
might be? I'm using the latest version of Xcode on Tiger.
Thanks,
Sam Stigler
