I have implemented the
didEnterRegion
method and it works in background for example if I show an alertview...even with the app in background (when I foreground the app the alertViews show)
I use alertview only to test the didEnterRegion method in background and it works...but now im trying to fire an UILocalNotification in didEnterRegion but the UILocalNotification is not firing. Theres my code:
-(void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
int iRegiao = [region.identifier intValue];
Location *ocorrencia = (Location *)[self.locations.objects objectAtIndex:iRegiao];
// NSLog(#"Voce está proximo da %#", ocorrencia.name);
// UIApplication *app = [UIApplication sharedApplication];
UILocalNotification *notification = [[UILocalNotification alloc] init];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
notification.fireDate = [NSDate date];// Now here you can manage the fire time.
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.alertBody = ocorrencia.name;
notification.alertAction = ocorrencia.name;
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
Are you targeting iOS 8? If so, you need to ask for permission for local notifications.
Try this:
if ([[UIApplication sharedApplication] respondsToSelector:#selector(registerUserNotificationSettings:)]) {
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeSound|UIUserNotificationTypeBadge categories:nil]];
}
The respondsToSelector: check is needed if you are also supporting iOS 7 or below.
Did you try to use - (void)presentLocalNotificationNow:(UILocalNotification *)notification on UIApplication? (it ignores fireDate)

I created a Local Notification that triggers 60 seconds when a certain button(SetButton) is clicked. My problem right now is if SetButton is pressed again, it does not override the first press, it displays 2 notifications and so on. How do I make sure that the second press of the button overrides the first press and there isn't a build up of notifications ?
- (IBAction)SetButtonPressed:(id)sender {
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60];
localNotification.alertBody = #"HEY GET UP";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
}
My AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if ([UIApplication instanceMethodForSelector: #selector(registerUserNotificationSettings:)]) {
[application registerUserNotificationSettings: [UIUserNotificationSettings settingsForTypes: UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]];
}
if (localNotification) {
application.applicationIconBadgeNumber = 0;
}
}
If you only use notifications for that specific action you could cancel all notifications at once using
[[UIApplication sharedApplication] cancelAllLocalNotifications];
It looks like you only have one type of local notifications in your app.
In that case you could keep it simple. Whenever you want to schedule a new one - cancel the previous one.
- (IBAction)SetButtonPressed:(id)sender {
[[UIApplication sharedApplication] cancelAllLocalNotifications];
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60];
localNotification.alertBody = #"HEY GET UP";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber =
[[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
}
I am currently doing this, but the notification repeats several times.Please help.
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive) {
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
//localNotification.userInfo = #"Hey";
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = self.notiname;
localNotification.fireDate = [NSDate date];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
AudioServicesPlaySystemSound(1104);
}
}
I'm building an app that allows its users to send each other messages. When a new message is received, it appears in the current user's Table view. I want my app to send the current user a notification when a new message arrives. Does anyone know how I might go about doing this?
I have notifications set up in my AppDelegate already:
appdelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Let the device know we want to receive push notifications
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
and I know the below code will allow me to fire a notification at a specified time (e.g. set by a picker):
// Get the current date
NSDate *pickerDate = [self.datePicker date];
// Schedule the notification
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = pickerDate;
localNotification.alertBody = self.itemText.text;
localNotification.alertAction = #"You are being notified!";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
// Request to reload table view data
[[NSNotificationCenter defaultCenter] postNotificationName:#"reloadData" object:self];
// Dismiss the view controller
[self dismissViewControllerAnimated:YES completion:nil];
How do I make a notification occur however when a new message is posted to the server (and appears in the tableview) for the logged in user?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert) categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];}
If your system is iOS8, you need to register permission.
UILocalNotification * notification = [[UILocalNotification alloc] init];
NSDate * pushDate = [NSDate dateWithTimeIntervalSinceNow:Time];
if (notification!=nil) {
notification.fireDate= pushDate;
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.repeatInterval = kCFCalendarUnitDay;
notification.soundName = UILocalNotificationDefaultSoundName;
notification.alertBody = #"Time O.K!";
NSLog(#"Ready");
notification.applicationIconBadgeNumber = 1;
//notification.applicationIconBadgeNumber = [[[UIApplication sharedApplication] scheduledLocalNotifications] count]+1;
NSDictionary * inforDic = [NSDictionary dictionaryWithObject:#"name" forKey:#"key"];
notification.userInfo =inforDic;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
You can have a try,this code I can successfully use on my device.
In iOS7.1 , when a user kills an app , does the geofencing still works?
If geofencing is detecting the device is entering or exiting the region, can it trigger a local notification (even when the user has killed the app ) ?
you GeoFencing still works it works like push notification / or passbook same thing it will still generate notification for your app. bellow function will fire even if app is not running in background.
- (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];
}
I am currently working on one iOS app, in which I am using [[UIApplication sharedApplication] setMinimumBackgroundFetchInterval:UIApplicationBackgroundFetchIntervalMinimum];. According to the docs I have implemented in this way .
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
NSLog(#"Launched in background %d", UIApplicationStateBackground == application.applicationState);
[[UIApplication sharedApplication] setMinimumBackgroundFetchInterval:UIApplicationBackgroundFetchIntervalMinimum];
i =0;
return YES;
}
-(void)application:(UIApplication *)application performFetchWithCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
NSLog(#"Fetch started");
++i;
// Set up Local Notifications
[[UIApplication sharedApplication] cancelAllLocalNotifications];
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
NSDate *now = [NSDate date];
localNotification.fireDate = now;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = #"BG Mode";
localNotification.applicationIconBadgeNumber = i;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
completionHandler(UIBackgroundFetchResultNewData);
NSLog(#"Fetch completed");
}
My issue is I have tried to debug it to know how frequently this method is calling . I didn't get any clarification. I have tested with timeinterval 60 seconds, but that is also not working . Please give me any ideas or suggestions . Thanks in advance .
Just to clarify, you've also set the UIBackgroundModes in Info.plist as per Apple's documentation ...
This property has no effect for apps that do not have the UIBackgroundModes key with the fetch value in its Info.plist file.
