Make an example... to execute action for specific date

Example showing how to use NSCalender, NSTimer and NSRunLoop class

The ASObjC script will setup date components for year, month, day, hour and minute.
Next using the NSTimer in NSRunLoop to perform action.

The code use 3 handlers include example.

Set the YYYY-MM-DD-HH-MM and save it as Applet.

make an example in objective-c to execute action for specific date by year, month, day

use framework "Foundation"
use scripting additions

set timeInterval to createCalendarWithComponents(2023, 7, 26, 16, 33) --> YYYY:MM:DD:HH:MM
set timerRunLoop to createTimerRunLoop(timeInterval, "performAction:")

on createTimerRunLoop(timeInterval, selector)
	if (timeInterval > 0) then
		set theTimer to current application's NSTimer's timerWithTimeInterval:timeInterval ¬
			target:me selector:selector userInfo:(missing value) repeats:false

			forMode:(current application's NSDefaultRunLoopMode)

			runUntilDate:(current application's NSDate's dateWithTimeIntervalSinceNow:timeInterval)
		display dialog "The target date is in the past."
	end if
end createTimerRunLoop

on performAction:sender
	display dialog ((current date) as string) & return & return & " Action performed at the specified date and time!"
end performAction:

on createCalendarWithComponents(yyyy, mm, dd, hh, theMinute)
	set theCalendar to current application's NSCalendar's currentCalendar()
	set dateComponents to current application's NSDateComponents's alloc()'s init()
