Hi,

Why would you use class “NSDate”'s instead of NSDate’s?

Thanks,

Hi,

in terms of AppleScript NSDate is just a variable, class “NSDate” is an object reference (like application “Finder”)

Hi Stefan,

Are they always interchangeable?

Thanks,
kel

#4

they what?

In the script, can you use either variables or object references? For instance, this:

can be exchanged with this:

Got it. Both forms work.

You can even use (without current application)

property NSDateFormatter : class "NSDateFormatter"

set myFormatter to NSDateFormatter's alloc()'s init()
#7

That’s what I was thinking about ‘current application’ also. I’m just trying to clean up my script.

Thanks a lot,
kel

#8

but this does not work

set myFormatter to class "NSDateFormatter"'s alloc()'s init()
#9

This works here:

set myFormatter to current application’s class “NSDateFormatter”'s alloc()'s init()

Don’t know if it matters but I switched everything into the applicationDidFinishLaunching handler. I think I might use ‘current application’ all the time as a rule until I get to know where it works and doesn’t work.

Thanks,
kel

I mean exactly this syntax without current application

#11

It works all the time at the root level of the script as in the property declaration 'parent: class “NSObject”.

Thanks for all the info,
