This is I am sure a fairly noob question, but I can't find the
answer in any of my books or online...what exactly is (id) sender.
I am forced to use with whenever i want to interact with a window,
a progress bar, etc, but I have no idea what it actually does
The sender variable represents the object that sent the action. For
example, if a button is clicked, the sender is the button.
A sender can be any sort of object, so actions tend to just specify
Objective-C's generic "id" type.
Now i am trying to launch a window if a certain circumstance is met
in my awakefromnib method but its saying sender is unrecognized and
I am finally very confused.
Post the code that isn't working.
