I am developing iOS app with both Push notification and Local Notification, I know how to remove 1 and all notification from center,
using
[[UIApplication sharedApplication]cancelAllLocalNotifications];
But my problem is if i have scheduled some local notifications ,
and a push notification is arrived so in didReceiveRemoteNotification
I am write
[[UIApplication sharedApplication]cancelAllLocalNotifications]; for clear notification center,
but it is cleared all my LocalNotification also...
EDIT
if there are total 3 notifiction in NC i.e. 1 is come from local notification and two from push( from server) in this case how can i handle it,? i am tap on 1st notification( comes from server) in NC. in this case what should do, my app badge should be 2.
then what should i do?
The cancelAllLocalNotifications will only cancel the local notifications, its even in the name! Not the push notifications as you can read in the documentation:
Cancels the delivery of all scheduled local notifications.
Since push notifications are server side there is noting to cancel in your app. To remove the push notification from the notification center just set the applicationBadegNumber to 0.
There is an option ,each notification contains a dictionary inside it, so when you creates any local notification add any key in dictionary which specifies that this notification is for local notification.so you can check that if it is not my local notification then i will remove it.
-(void)scheduleLocalNotification{
[self cancelAlarm]; //clear any previous alarms
UILocalNotification *alarm = [[UILocalNotification alloc] init];
alarm.alertBody = #"alert msg";
alarm.fireDate = [NSDate dateWithTimeInterval:alarmDuration sinceDate:startTime];
alarm.soundName = UILocalNotificationDefaultSoundName;
NSDictionary *userInfo = [NSDictionary dictionaryWithObject:#"localNotification" forKey:#"localNotification"];
alarm.userInfo = userInfo;
[[UIApplication sharedApplication] scheduleLocalNotification:alarm];
}
-(void)cancelNotification{
for (UILocalNotification *notification in [[[UIApplication sharedApplication] scheduledLocalNotifications] copy]){
NSDictionary *userInfo = notification.userInfo;
if (![self.key isEqualToString:[userInfo objectForKey:localNotification]]){
[[UIApplication sharedApplication] cancelLocalNotification:notification];
}
}
}
The applicationbadgenumber is managed by you. Deleting scheduled notifications will not change that number. You must manage that yourself. I gave a presentation a while back that might help. http://www.youtube.com/watch?v=ixQqZWtn0pg Start watching at 11:50.

How to save the local notification? I want to use the local notification fire date again to schedule local notification.
You should use UILocalNotification
Please check out documentation: https://developer.apple.com/library/ios/documentation/iPhone/Reference/UILocalNotification_Class/
It look something like:
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = dateTime;
localNotification.alertBody = [NSString stringWithFormat:#"Alert Fired at %#", dateTime];
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
About notification re-schedule cycle:
Firing the notification is not enough to show up another one. Your app won't be launch except if user tap the notification.
You could pre-schedule a notification for every day or week for the next month and unschedule them if user open one. Depending of your need you could also fire a remote notification with a content-available key which will launch your app in background and allow you to reschedule a new local notification.
I am working on a dummy project in xcode 6 and creating local notifications. I have created and deleted these local notifications.Now I want to edit a particular notification.
You cannot change an already scheduled notification.
You will have to cancel, and re-create it with the new data you need.
You can ask the current scheduled UILocalNotifications:
NSArray *scheduledNotifications = [[UIApplication sharedApplication] scheduledLocalNotifications];
Loop the array and do a check if its the notification you need to change:
for (UILocalNotification *notification in scheduledNotifications)
{
//Get the ID you set when creating the notification
NSDictionary *userInfo = notification.userInfo;
NSNumber *someValueYouGaveWhenCreatingCouldBeAnIdentifierOfAnObject = [userInfo objectForKey:#"someKey"];
if (someValueYouGaveWhenCreatingCouldBeAnIdentifierOfAnObject == someCheckYouHaveToDoHere)
{
[[UIApplication sharedApplication] cancelLocalNotification:notification];
//Re-create the localnotification with new data and the someValueYouGaveWhenCreatingCouldBeAnIdentifierOfAnObject
break;
}
}
My title might not accurately depict my question, so I apologize. I have looked for a solution to creating this level of functionality but I am unable to find it.
I am creating a VoIP application for iOS 8. When a user receives a call I am displaying a notification with a 12 second ringtone. While this notification is in progress if the call disconnects I want the Incoming Call notification to disappear and display a Missed Call notification immediately. This level of functionality is possible because Viber does it.
Currently, I am sending a silent push notification when a Incoming Call is available. This is my payload...
aps = {
"content-available" = 1;
};
category = INCOMING;
from = "+15555554220";
Upon receiving the silent push I am creating a Local Notification like this ...
if ([userInfo[#"category"] isEqualToString:#"INCOMING"]) {
NSLog(#"application: didReceiveRemoteNotification: fetchCompletionHandler: Incoming Call Notification Received");
NSLog(#"application: didReceiveRemoteNotification: fetchCompletionHandler: Sending Local Notification For Incoming Call");
// Get Caller Contact Info
NSDictionary *contact = [self findContactInfoForNumber:userInfo[#"from"]];
NSString *message = [NSString stringWithFormat:#"Incoming Call: %#",userInfo[#"from"]];
if (contact != nil) {
message = [NSString stringWithFormat:#"Incoming Call: %# %#",contact[#"firstName"],contact[#"lastName"]];
}
UILocalNotification *notification = [[UILocalNotification alloc] init];
NSMutableDictionary *infoDict = [NSMutableDictionary dictionaryWithObject:#"Incoming Call" forKey:#"type"];
notification.userInfo = infoDict;
notification.category = #"INCOMING_CALL_CATEGORY";
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:1];
notification.alertBody = message;
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.soundName = #"ring.m4a";
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
Then, once the call is disconnected I am sending another silent push notification for a missed call...
aps = {
"content-available" = 1;
};
category = MISSED;
Once received I am canceling all local notifications like this...
if ([userInfo[#"category"] isEqualToString:#"MISSED"]) {
NSLog(#"application: didReceiveRemoteNotification: fetchCompletionHandler: Missed Call Notification Received");
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
}
The issue I am encountering is that on the lock screen it behaves exactly the way I want it to. I receive the incoming call notification and when the caller hangs up that notification immediately disappears from notification center and a missed call notification is there in the place of it. However when the phone is on the home screen. A banner is shown and then it plays the whole ringtone then displays the missed call. Does anyone know the reason why this is happening? Does anyone have any solutions to achieve this level of functionality? Like I said before the app Vider is a prime example of what I want my app to do.
Thanks you in advance.
I'm making an applikation which is using push notifications, I am currently using pushbots for the push notifications. I was wondering if there is any way to intercept the notifications that is received by the application and check the notification before the notification is shown on the device. And if the data in the notification is not correct, dont show a notification at all? Is this possible with pushbot or do I need to do it all by my self?
Yes, you can achieve this behaviour playing around with Local Notifications.
You can configure your payload without an alert and "content-available": "1" so your application can receive notifications without showing them to the user.
// Payload
{
aps: {
"content-available": 1
},
text: 'my alert message' // your custom info
}
And in your app code, register notifications as
// Register notifications
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
UIRemoteNotificationTypeNewsstandContentAvailability];
Then, the key is to trigger Local Notifications in the application:didReceiveRemoteNotification:fetchCompletionHandler: method based on some condition
- (void)application:(UIApplication *)application didReceiveRemoteNotification: (NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
NSLog(#"push data package: %#", userInfo);
// Retrieve your data
NSString *text = [userInfo objectForKey:#"text"];
BOOL mustShow = YES;
// Only show notification if app is background and your custom condition
if ((state == UIApplicationStateInactive || state == UIApplicationStateBackground)
&& mustShow) {
// Raise the local notification a second after received
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:1];
localNotification.alertBody = text;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
}
This way you can "intercept" the notifications before "displaying" them to the user.
You can't prevent the notification from being shown once it reaches the device (assuming it contains an alert field in the aps dictionary - if it doesn't, no notification will be shown anyway).
You should determine in your server which notifications should be sent to which device tokens. You can associate device tokens with users in your DB, if your functionality requires it.
Even if what you request was possible, it would be very inefficient to send notifications to all the devices that installed your app, and then only display the notification in a small subset of them.
I got my push notification successfully in both background and foreground but my problem is when my application is in active state/foreground and push notification is arrived then i show this pushnotification message on alertview using didReceiveRemoteNotification method,
My alert view have two buttons
1) later
2) Ok.
If I press 1) "later" button then I want add this pushnotification message in notification area so after some time user can see and tap on that particular push notification and go with that and that record of push notification will remove from notification area.
This is not possible. There is no API to access notification are of iOS.
Alternative
What near alternative you can try is Local Notification. When user select later set Local Notification for that thing. You can add this Local Notification when user leave your app so that you don't get notification while user is continue with your application.
Better Approach
The most general approach for this problem is Notification screen in app. Your application has one screen which has list of received notification so that user can check that in you app. I suggest you to go with this. Because this is most common and clear idea.
You need to implement core data for Notifications but it can only happen when your Application is is Active state.
1-create a new identity everytime a new notification arrive.
2-save it.
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSDictionary *Notification = userInfo;
NSString *title = [(NSDictionary*)[(NSDictionary*)[Notification valueForKey:#"aps"] valueForKey:#"alert"] valueForKey:#"title"];
NSString *body = [(NSDictionary*)[(NSDictionary*)[Notification valueForKey:#"aps"] valueForKey:#"alert"] valueForKey:#"body"];
XXNotification *objNotification = [XXNotification create];
objNotification.title = title;
objNotification.detail = body;
[XXNotification save:nil];
NSArray *arrNotification =[XXNotification allUnRead:nil];
[UtilityFunctions setApplicationBadgeNumber:[arrNotification count]];//Utility functions is my class for common functions.
if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive)
{
[UtilityFunctions showAlertView:title message:body delegate:self cancelButtonTitle:#"Ok" otherButtonTitle:#"Cancel" withTag:99 withAccessibilityHint:[NSString stringWithFormat:#"%#:|:%#", title,body]];
}
else if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateInactive || [[UIApplication sharedApplication] applicationState] == UIApplicationStateBackground)
{
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.userInfo = userInfo;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = body;
localNotification.fireDate = [NSDate date];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
if (![IsLocationSaved isEqualToString:#"NO"])
{
[[NSNotificationCenter defaultCenter]postNotificationName:kNotificationForShowingNotification object: nil userInfo:nil];
}
}
}
On showing the UIAlertView, on its click event either delete that notification in DB or make a bool in it as isRead and make it YES. then save it,
On Notifications list Query the notification from DB or only those whose isRead = NO.
That is the way I did it in My Application.
