iOS Scheduling a local notification


Make sure you see Registering for local notifications in order for this to work:


let notification = UILocalNotification()
notification.alertBody = "Hello, local notifications!"
notification.fireDate = NSDate().dateByAddingTimeInterval(10) // 10 seconds after now


UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.alertBody = @"Hello, local notifications!";
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10]; // 10 seconds after now
[[UIApplication sharedApplication] scheduleLocalNotification:notification];

To see the notification in the iOS Simulator, type ^⌘H (control-command-H) to go home and then type ⌘L (command-L) to lock the device. Wait a few seconds, and the notification should appear (this appearance will vary depending on notification type discussed in "Registering for local notifications"):

Swipe on the notification to get back to the app (note that if you called this in the first view controller's viewDidLoad, viewWillAppear, viewDidAppear, etc., the notification will be scheduled again).
