I've searched other questions similar to this here and I can't find any that seem to actually work. What I'm trying to do is when the user opens the app from a local notification, I need it to execute some code (such as opening the UIMessageComposer or displaying a UIAlertView). Anyone have any idea on how I would do this? Just as a note it is a local notification not a push notification.
You need to implement this method in you AppDelegate.m file
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
You can do want you want in this.
Here's a good tutorial on how to work with Local notifications. http://www.appcoda.com/ios-programming-local-notification-tutorial/
use this
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Reminder"
message:notification.alertBody
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}

Im trying to implement the local notification to my app and I implemented the local notification but the problem is .... I'm not getting the Notification BANNER and SOUND when my app is in the foreground. But it is working good when my app is in background.
How to bring the notification banner and sound in foreground.. Is that possible?
this is my piece of code...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Handle launching from a notification
UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (locationNotification) {
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}
}
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
if (application.applicationState == UIApplicationStateActive ) {
NSLog(#"it entered active push");
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.userInfo = userInfo;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = userInfo[#"aps"][#"alert"][#"body"];
localNotification.alertLaunchImage= userInfo[#"acme1"];
localNotification.fireDate = [NSDate date];
localNotification.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
// Remove the badge number
application.applicationIconBadgeNumber = 0;
}
-(void)application:(UIApplication*)application didReceiveLocalNotification:(UILocalNotification *)notification{
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Reminder"
message:notification.alertBody
delegate:self cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}
If the app is active you will be notified by application:didReceiveLocalNotification: in app delegate only. There you can display custom banner like view on the top viewcontroller presented on the view hierarchy . Just look at the whatsapp notification when the app is open
If the application is active then you will not recieve any sound, badge or alert, however the application delegate application:didReceiveLocalNotification: will be called
From apple docs
If the application is foremost and visible when the system delivers the notification, no alert is shown, no icon is badged, and no sound is played. However, the application:didReceiveLocalNotification: is called if the application delegate implements it. The UILocalNotification instance is passed into this method, and the delegate can check its properties or access any custom data from the userInfo dictionary.
If your app is currently running and active (i.e. visible), you will not see the alert message. Instead iOS will deliver the notification to your app directly through the following method
- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification
No it will not play a sound or show a banner. However in your apps delegate , did receive notification will still be called where you can then show an alert view if you wish to notify a user.
You can however add audio manually.
- (void) application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification
{
SystemSoundID systemSoundID;
NSURL *soundURL = [[NSBundle mainBundle] URLForResource:#"blip"
withExtension:#"mp3"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)soundURL, &systemSoundID);
AudioServicesPlaySystemSound(systemSoundID);
}
Local notification in Foreground
I'm using Urban airship in my app to receive push notifications and all works as expected.
The problem is that when my app is running in foreground and a push received it shows Notification as title along with info in payload.But i want to show title as Notis instead Notification i tried this-
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
if ( application.applicationState == UIApplicationStateActive )
{
NSDictionary* aps = [userInfo valueForKey:#"aps"];
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:#"Notis" message:[aps valueForKey:#"alert"] delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
else
{
UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;
tabBarController.selectedIndex=2;
[self loadStatisticsInBackground];
[[UAPush shared] handleNotification:userInfo applicationState:application.applicationState];
}
[[UAPush shared] resetBadge];
}
But it shows two alerts one that i defined and another is system defined.
Any help would be appreciated.
Edit: Ok.. if it is not possible to change title of push notification then Is there any way that we can prevent push alert when app is running in foreground?I don't want to show when my app is running in foreground?
You can just detect if your app is running in foreground and if it does, you don't pass the notification to UAPush in -application:didReceiveRemoteNotification:.
Hello everyone,
I am trying how to implement pushnotification.For this i have read apple official document for push notification and also read raywenderlich blog and i understand the flow of pushnotication very well. I have created development and production certificate,profile and its working fine and push was successfully sent and receiving in -
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
*** display message in uialertview******
}
but my problem is how can i display push in my device like other push notification on top up side for both when my application is foreground and background too.
currently i am trying for IOS 7.0 and XCode Version 5.1.1 (5B1008)
Thanks In advance.
First of all check via these methods in App Delegate that if your registered successfully to APNS.
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
}
-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
}
then in
-(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"];
if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive)
{
}
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 your application is in active state show UIAlertView. if its not you need to show a UILocalNotification.
When you are in Background mode then push notification will display as per your application notification settings from notification centre. you dont have to display ios will do that.
when you are in Foreground mode then notification will receive and -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo method will be called. so using this method you get userinfo. just NSLog userinfo dictionary and then you can create customview with label at top and animate it like ios default banner.
Hope this will help you.
As per Apple's note push/local notification will be display only when app is background mode. If notification is arrive at the time of app is on foreground/active then you need to manually manage it because iOS won't show a notification banner/alert That's default design.
I just put my logic here for manage notification when app in foreground mode:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
// check the application state for app is active or not.
if (application.applicationState == UIApplicationStateActive)
{
// Nothing to do if applicationState is Inactive, the iOS already displayed an alert view.
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Receive a Remote Notification" message:[NSString stringWithFormat:#"Your App name received this notification while it was running:\n%#",[[userInfo objectForKey:#"aps"] objectForKey:#"alert"]]delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
}
If you want to receive notification in top of the device like banner style then follow these steps.
First, you need to launch the 'Settings' app on your iOS device.
Once you're in, choose 'Notifications' from the list of options.
Here's a list of every app that supports push notifications. The ones at the top have been granted permission by you
You can also set the alert style. You can choose the banners that conveniently appear at the top of the screen, or full-on pop-ups that force you to take action before they go away. Or you can just choose 'None'.
For more detail check this link.
Hope you will get something from my answer.
Hi Im currently developing an app where i have push notifications activated. I use parse.com. I have got it working so far that i can send a notification and the device receives it and i also get a badge on the app. But when i open the nothing happens and the badge does not disappear. I've set it in my appdelegate.m so parse is handling the push notifications. Heres some code that im using:
- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken {
// Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:newDeviceToken];
[currentInstallation saveInBackground];
}
and also:
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
}
Thanks
Ok thaks but how to i show the content of the push notification in the alert view? Or is that not a problem do i just have to configure a alertview with no text?
There are two scenarios:
App closed
When the app is closed and the user taps on a notification it's like when taps on the app icon. The app starts from application:didFinishLaunchingWithOptions:. To know if the app is opened normal (tap icon) or with a notification, just check the dictionary launchOptions for the key UIApplicationLaunchOptionsRemoteNotificationKey.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSDictionary * pushDictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (pushDictionary)
{
//AlertView
}
}
App opened
When the app is opened there are two possible case
App in background UIApplicationStateInactive
App in foreground UIApplicationStateActive
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
if (application.applicationState == UIApplicationStateInactive)
{
//AlertView
}
else if (application.applicationState == UIApplicationStateActive)
{
// AlertView
}
}
pushDictionary and userInfo are exactly the same dictionary that represents the notification.
Edit 1
A push notification is a JSON file that iOS automatically convert into a NSDictionary. The standard configuration is:
{"aps":
{
"alert":"Text message",
"sound":"default",
"badge":"1" //the number shown on the app's icon
}
}
From this base you can extend the JSON and put inside your own content. For example
{"aps":
{
"alert":"Text message",
"sound":"default",
"badge":"1" //the number shown on the app's icon
},
"Name":"Fry"
}
Now you can retrive the name in this very simple way:
NSString * name = userInfo[#"Name"];
and show it in the alert.
Edit 2
To show the content of push in UIAlertView just do this:
UIAlertView *av = [[UIAlertView alloc] initWithTitle:name
message:name
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"Ok", nil];
[av show];
If you receive push notification while your app isn't active (killed)
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
will not be triggered. Instead of that you will have to use object with key UIApplicationLaunchOptionsRemoteNotificationKey from launchOptions dictionary inside
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
Recently I am trying to create an alarm clock, and when I use UILocalNotification, the problem occur. It will show a banner when the app is in background, but when the app is active, even thought I have used didReceiveLocalNotification, there is no reaction at all.
Why?
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
UIApplicationState state = application.applicationState;
if (state == UIApplicationStateActive) {
NSLog(#"RingRingRing~~~~~");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Remind" message:notification.alertBody delegate:self cancelButtonTitle:#"Sure" otherButtonTitles:nil, nil];
[alert show];
}
}
Neither Remote or local notifications does not wakeup the application in iOS. it takes a user's action on the notification to launch the app.
