Im currently working with the "Regions" Sample code: https://developer.apple.com/library/ios/#samplecode/Regions/Introduction/Intro.h tml#//apple_ref/doc/uid/DTS40010726-Intro-DontLinkElementID_2
I'd like to take it a step further and generate, or fire, a notifcation when the user exits the region (can be for both enter & exit, i don't mind, whatever is easiest for an initial implementation).
I have been looking at the CLLocation Class reference, Location Awareness Programming Guide and Local and Push Notification Programming guide. And im suffering from information overload.
Many thanks :)
EDIT: I think i may have an idea which solves the problem: in the RegionsViewController implementation file there is this:
- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
NSString *event = [NSString stringWithFormat:@"didExitRegion %@ at %@", region.identifier, [NSDate date]];
[self updateWithEvent:event];
}
Since i want to implement a local notification when the user exits the designated region boundary i've input this:
- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
NSString *event = [NSString stringWithFormat:@"didExitRegion %@ at %@", region.identifier, [NSDate date]];
[self updateWithEvent:event];
//implement local notification:
UIApplication *app = [UIApplication sharedApplication];
UILocalNotification *notification = [[UILocalNotification alloc] init];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
if (notification == nil)
return;
notification.alertBody = [NSString stringWithFormat:@"Did You Lock Your House?"];
notification.alertAction = @"Lock House";
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 1;
[app presentLocalNotificationNow:notification];
[notification release];
}
Could somebody advice me as to whether this is correct, or if there are any recommendations? (apologies for the poor formatting)
