È possibile aggiungere un osservatore su NSWorkspace.sharedWorkspace().notificationCenter
per la chiave NSWorkspaceDidActivateApplicationNotification
. Puntate il selettore su uno dei vostri metodi e prendete le informazioni dal dizionario userInfo
.
semplice esempio nel AppDelegate:
Swift 2,2
func applicationDidFinishLaunching(notification: NSNotification) {
NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self,
selector: #selector(activated),
name: NSWorkspaceDidActivateApplicationNotification,
object: nil)
}
func activated(notification: NSNotification) {
if let info = notification.userInfo,
app = info[NSWorkspaceApplicationKey],
name = app.localizedName {
print(name)
}
}
Swift 3
func applicationDidFinishLaunching(_ aNotification: Notification) {
NSWorkspace.shared().notificationCenter.addObserver(self,
selector: #selector(activated(_:)),
name: NSNotification.Name.NSWorkspaceDidActivateApplication,
object: nil)
}
func activated(_ notification: NSNotification) {
if let info = notification.userInfo,
let app = info[NSWorkspaceApplicationKey] as? NSRunningApplication,
let name = app.localizedName
{
print(name)
}
}
