Sleep Apple Event not being issued in System Process
Hi everyone!
I'm developing my first Mac OS X application, and I'm having some problems with an AppleEvent that I want to send to the system.
Firstly, I found an article on how to programmatically shutdown, restart, sleep or logout an apple computer Link, which is the main objective I want to achieve with the application.
Well, I've tested that code and works perfectly fine as it is, but what I need to do is to use it on a GUI and run it on a cycle loop defined by the user so the computer will sleep/wake up or restart (power off/power on) automatically when certain period of time has passed.
This is for testing purposes on certain PCI SSDs, so when the computer can't wake up/restart itself the piece it's considered a failure and it's segregated.
I'm totally new on the Objective C/Swift programming environment, I have read some tutorials, but can't quite understand Objective C completely whereas I do understand Swift.
I adapted the code and bridged the two languages so I can make use of an Objective-C object that has the functions that perform the previous mentioned processes.
The problem here is:
*The code prints a certain line that says that the computer is going to sleep, (which was on the example code previously provided), but now as it interfaces with Swift and the GUI it appears to do nothing but show the date I formatted to be shown on a TextField I declared before.
I really don't know what's going on here, and I'm sorry if I'm being too clumsy on my coding but I will really appreciate any help.
