Review the docs on NSTextField, its delgates and NSUserDefaults.
2. Can an NSButton be set up to trigger the Action at
a target AppController to retrieve a Preference and
display it in an NSTextField.
Yes it can but not sure why you need to have a button to trigger this
when it can be done at initialization time and on notification of a
change.
Anyway a quick run down... setup the button to target your app
controller instance and a particular action. Then have that action use
NSUserDefaults to read in what is needed and finally set the
NSTextFields value (using an outlet pointed at it).
This seemed like such an easy thing to do but now its
like I'm trying to create a lightbulb from scratch...a
few well written lines would be of great help.
It is easy but one part of it requires using IB to either setup the
target/action or bind things for the button (or do you really want to
do it programatically) as well as setting up an outlet to the text
field.
If you used bindings then all you would need to do is bind the text
field value to the user defaults control using the key of the
preference in question using IB.
