Continuing with my application I'm still working on my application,
dealing with my workout form view. This view contains several fields
and a table. Overall each form will relate to an object that contains
fields like:
workoutDate
heartRate data
min
average
peak
calories
notes
array of routines (which will be shown in an NSTableView
routine
name
set
reps1
reps2
reps3
weightsPerSet1
weightsPerSet2
weightsPerset3
While researching I found out about the ObjectController and
NSArrayController (particularly in reference to creating an
NSTableView). Initially I was going with creating my own controller
but I like the idea of directly binding my view fields to directly to
my object. So, my question is if I were going to use the
ObjectController should I just go ahead and extend this controller to
gain the benefits of direct object binding? If so should I
encapsulate an instance of NSArrayController to get the benefits for
the NSTableView. Or is there another pattern that I should be
following here?
Oh, I'm also assuming that when using something like the
ObjectController I can bind to fields using syntax like this (which,
by the way, I haven't actually found any references to in the
documentation) heartRate.min, heartRate.average, etc.
Just getting used to Cocoa and its APIs, thanks in advance for any help.
