Here is my AppDelegate.swift. I implement the applicationShouldTerminate protocol from NSApplication. Which answer I give depends on the status of is.Started in the mainWindowController. (This is the SpeakLine example from Cocoa Programming for OS X: The Big Nerd Ranch Guide 5/e—I'm trying to take the example one step further and keep the program from being allowed to quit while the talking is going on.)
What I want to do is change TerminateReply.TerminateCancel to TerminateReply.TermianteLater and then send NSApplication the replyToApplicationShouldTerminate(true) signal when the talking is done. As it stands now in the MainControllerWindow.swift class I have a function set up to handle state changes in the Speech Synthesizer and that's where I want to call it.
import Cocoa
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
var mainWindowController: MainWindowController?
func applicationDidFinishLaunching(aNotification: NSNotification) {
let mainWindowController = MainWindowController()
mainWindowController.showWindow(self)
self.mainWindowController = mainWindowController
}
func applicationShouldTerminate(sender: NSApplication) -> NSApplicationTerminateReply {
if (mainWindowController!.isStarted) {
return NSApplicationTerminateReply.TerminateCancel
} else {
return NSApplicationTerminateReply.TerminateNow
}
}
}
The trouble is, when I put it here, I get an error.
var isStarted: Bool = false {
didSet {
updateButtons()
NSApplication.replyToApplicationShouldTerminate(true)
}
}
it tells me I can't use a bool. It also tells me I can't use an Objective C bool when I try to put YES. How do I tell NSApplication it's OK to quit now?
