I am working on VOIP iOS app in which i have to show a local notification when call comes and app is in background mode i make it like this
Register Notifications in appdelegate
UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
showing Notification
if ([UIApplication sharedApplication].applicationState != UIApplicationStateActive) {
UILocalNotification* localNotif = [[UILocalNotification alloc] init];
if (localNotif) {
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.alertTitle = #"Call From";
localNotif.alertBody = [NSString stringWithFormat:#"%#", callerName];
localNotif.alertAction = #"Receive";
localNotif.applicationIconBadgeNumber = 1;
localNotif.fireDate = [NSDate date];
localNotif.userInfo = #{#"name":callerName};
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
}
the local notification show as alert on top but when user not attend the call or other user disconnect the call, local notification removed automatically from Notification centre which is very weird, i googled too much but no success suggest some solution.
Thanks in advance.

-(void)setNoti {

Why my simple UILocalNotification is not firing?
Have you added this code in didFinishLaunchingWithOptions of AppDelegate
UIUserNotificationType types = (UIUserNotificationType) (UIUserNotificationTypeBadge |
UIUserNotificationTypeSound | UIUserNotificationTypeAlert);
UIUserNotificationSettings *mySettings =
[UIUserNotificationSettings settingsForTypes:types categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
I am not sure you added or not, but if you missed this, you will never get local as well as remote notification.
You have To Register Notification setting For Local and Remote Notification both Please Register notification setting First.
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.
Can someone please take a look at the following code and tell me why the local notification isn't firing. Im running the app in XCode and using the debug option to simulate a background fetch but the local notification doesn't fire.
- (void)application:(UIApplication *)application performFetchWithCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
NSLog(#"performFetchWithCompletionHandler");
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif) {
localNotif.alertBody = #"Update demo text!";
localNotif.alertAction = #"OK";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.fireDate = nil;
NSLog(#"Local Notification");
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
//Perform some operation
completionHandler(UIBackgroundFetchResultNewData);
}
Do you query the user to allow push?
if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIUserNotificationTypeSound categories:nil];
[application registerUserNotificationSettings:settings];
}
Instead of checking device version, use below code that checks RespondToSelector:
if ([UIApplication instancesRespondToSelector:#selector(registerUserNotificationSettings:)])
{
[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
}
I am stuck with the strange problem. I am making an alarm application.When i fire a local notification it works fine in simulator but when I compile the code in an iPhone it dose not working.Same code is working on an simulator and not responding on a iPhone.
notification code:
-(void) scheduleLocalNotificationWithDate:(NSDate *)fireDate
{
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = fireDate;
localNotif.alertBody = #"Time to wake Up";
localNotif.alertAction = #"Show me";
localNotif.soundName = #"Tick-tock-sound.mp3";
localNotif.applicationIconBadgeNumber = 1;
localNotif.repeatInterval = NSCalendarUnitWeekOfYear;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
and save button code is:
- (IBAction)saveBtn:(id)sender {
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.timeZone = [NSTimeZone localTimeZone];
NSLog(#"time is %#",dateFormatter.timeZone);
dateFormatter.timeStyle = NSDateFormatterShortStyle;
NSString * dateTimeString = [dateFormatter stringFromDate:timePicker.date];
datesArray = #[[dateFormatter stringFromDate:self.timePicker.date]];
}
Please tell me the solution. Thanks
Write this code in appdelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
if ([application respondsToSelector:#selector(registerUserNotificationSettings:)]) {
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge |
UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
} else {
// Register for Push Notifications before iOS 8
[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeSound)];
}
return Yes;
}
When my app goes in background then applicationDidEnterBackground is automatically called and in this method we fire local notification. but didReceiveLocalNotification: method is not called
- (void)applicationDidEnterBackground:(UIApplication *)application {
UIApplication *app = [UIApplication sharedApplication];
bgTask = [app beginBackgroundTaskWithExpirationHandler:^{
bgTask = UIBackgroundTaskInvalid;
}];
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.fireDate = [NSDate date];
localNotification.alertBody = textString;
localNotification.alertAction = #"View";
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] presentLocalNotificationNow:localNotification];
}
Your expectations with local notifications are incorrect:
When your app will go in background then you will see an immediate notification on your phone but you have to tap that notification to trigger didReceiveLocalNotification delegate.
If you receive local notification in foreground then didReceiveLocalNotification will be triggered automatically.
Above scenario is tested and verified.
Update: You must read this documentation:
http://www.thekspace.com/home/component/content/article/62-uilocalnotification-demystified.html
Try this code:
NSDate *pickerDate = [date_picker date];
// Schedule the notification
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = pickerDate;
localNotification.alertBody = #"Alert Body Message";
localNotification.alertAction = #"Alert Action Message";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
and use this code in didFinishLaunchingWithOptions in App delegate class.
UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (locationNotification) {
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}
Before scheluding notification you must register it for specified type:
- (void)applicationDidEnterBackground:(UIApplication *)application {
UIApplication *app = [UIApplication sharedApplication];
bgTask = [app beginBackgroundTaskWithExpirationHandler:^{
bgTask = UIBackgroundTaskInvalid;
}];
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.fireDate = [NSDate date];
localNotification.alertBody = textString;
localNotification.alertAction = #"View";
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.applicationIconBadgeNumber = 1;
// register notification settings
if ([application respondsToSelector:#selector(registerUserNotificationSettings:)]) {
#ifdef __IPHONE_8_0
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
|UIRemoteNotificationTypeSound
|UIRemoteNotificationTypeAlert) categories:nil];
[application registerUserNotificationSettings:settings];
#endif
} else {
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[application registerForRemoteNotificationTypes:myTypes];
}
[[UIApplication sharedApplication] presentLocalNotificationNow:localNotification];
}
