I have an app that will set an alarm for the user. The alarm is a basic UILocalNotification with a sound file that is 12 seconds long. The sound plays on the device but it does not go away when the use dismisses the notification. I got it to stop playing sound on the simulator by using this
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
[[UIApplication sharedApplication] cancelLocalNotification:localNotif];
}
return YES;
}
Any help would be great.
Thank you
I put this on my AppDelegate and it works.
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
[[UIApplication sharedApplication] cancelAllLocalNotifications];
}
Hope it help.

I have implemented push notifications in my iOS8 app. I am trying to play an audio file once the notification is received.
The code is playing the audio when the app is in the foreground, but when the app is in the background, nothing happens.
I have tried regenerating the certificates and provisioning profiles. And I have made sure that the app is running in the background, i.e. the user has not swiped up to remove it. In Background modes, I have enabled Remote Notifications, Background Fetch and Audio & Airplay.
I have added code snippets from my AppDelegate.m file:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// More code here ---------------------------------------------------
if (launchOptions) {
NSDictionary *userInfo = [launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
NSDictionary *apsInfo = [userInfo objectForKey:#"aps"];
if (apsInfo) { //apsInfo is not nil
[self performSelector:#selector(playCarAlarmAudio)
withObject:nil
afterDelay:1];
}
}
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
[[UIApplication sharedApplication] registerForRemoteNotifications];
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge
|UIUserNotificationTypeSound
|UIUserNotificationTypeAlert) categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}
// More code here ---------------------------------------------------
}
The delegate methods to handle push notifications:
-(void) application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
NSLog(#"Failed to register for push");
}
-(void) application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
}
-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[self respondToEventNotification:userInfo];
}
-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
// [self respondToEventNotification:userInfo];
[self playAlarmAudio];
}
-(void) respondToEventNotification : (NSDictionary *) userInfo {
if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateBackground) {
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
[localNotification setSoundName:#"alarm.mp3"];
[localNotification setFireDate:[NSDate date]];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
else if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive) {
[self playAlarmAudio];
}
}
And to play the Alarm:
-(void) playAlarmAudio {
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"alarm" ofType:#"mp3"];
NSURL *fileUrl = [NSURL fileURLWithPath:filePath];
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileUrl error:nil];
self.audioPlayer.numberOfLoops = 1;
[self.audioPlayer play];
}
According to the following Apple documentation, the notification sound to be played is specified inside the notification payload dictionary (https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html):
The Notification Payload
Each remote notification includes a payload. The payload contains information about how the system should alert the user as well as any custom data you provide. In iOS 8 and later, the maximum size allowed for a notification payload is 2 kilobytes; Apple Push Notification service refuses any notification that exceeds this limit. (Prior to iOS 8 and in OS X, the maximum payload size is 256 bytes.)
For each notification, compose a JSON dictionary object (as defined by RFC 4627). This dictionary must contain another dictionary identified by the key aps. The aps dictionary can contain one or more properties that specify the following user notification types:
An alert message to display to the user
A number to badge the app icon with
A sound to play
I am trying to register for push notifications in my iOS app. But it is calling neither the didRegisterForRemoteNotificationsWithDeviceToken nor didFailToRegisterForRemoteNotificationsWithError callback methods. I have revoked and regenerated the provisioning profile for the app.
I am using iOS8 and I have enabled the following background modes in my Info.plist
App registers for location updates
App downloads content in response to push notifications
App downloads content from the network
The code is:
-(void) application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
NSLog(#"Failed to register for push");
}
-(void) application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSLog(#"did succeed in register for push");
// Get the device token string
const char* data = [deviceToken bytes];
NSMutableString* token = [NSMutableString string];
for (int i = 0; i < [deviceToken length]; i++) {
[token appendFormat:#"%02.2hhX", data[i]];
}
[[NSUserDefaults standardUserDefaults] setObject:token forKey:#"DeviceToken"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[self respondToEventNotification:userInfo];
}
-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
[self respondToEventNotification:userInfo];
}
Have you register your app with didFinishLaunchingWithOptions method for iOS8 like,
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
[[UIApplication sharedApplication] registerForRemoteNotifications];
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
|UIRemoteNotificationTypeSound
|UIRemoteNotificationTypeAlert) categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}
else
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}
You have to consider registration process of Push Notification in iOS8.
May this help you.
I have an app that when it launches it plays an intro clip. The following code is in the - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions within the appDelegate.m which works just splendid.
NSLog(#"PLAY SOUND CLIP WHILE LOADING APP");
NSURL *clip = [[NSBundle mainBundle] URLForResource: #"intro" withExtension:#"caf"];
self.startupPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:clip error:NULL];
[self.startupPlayer play];
If the user changes view before the intro sound finishes it still continues to play. I have placed this code outside of - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions thinking it would help but no.
-(void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
// Stop Sound
[self.startupPlayer stop];
}
I thought maybe if I put an if statement right after the load request that might do the trick but it has not worked. See example:
NSLog(#"PLAY SOUND CLIP WHILE LOADING APP");
NSURL *clip = [[NSBundle mainBundle] URLForResource: #"intro" withExtension:#"caf"];
self.startupPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:clip error:NULL];
[self.startupPlayer play];
if ([viewDidDisappear == YES]) {
[self.startupPlayer stop];
}
Any suggestions that would stop the intro sound if the user changes view before that clip is done playing would be great. Oh and I've used the "viewWillDisappear" in other parts of the app with success, but in this case I choose "viewDidDisappear" because the later didn't work either. So I'm stumped. Thanks in advance.
EDIT: So I moved the viewWillDisappear into my MainViewController and called the delegate but I'm still not having any luck. Again, help would be appreciated.
I solved this issue by taking the #property declaration for *startupPlayer and placing it in the AppDelegate.h file instead of how it was below;
In the AppDelegate.m
#interface AppDelegate ()
#property (nonatomic, strong) AVAudioPlayer *startupPlayer;
#end
Then I still #synthesized it in the .m file as shown below and kept the didFinishLaunchingWithOptions the same:
#implementation AppDelegate
#synthesize startupPlayer = _startupPlayer;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
//------ PLAY SOUND CLIP WHILE LOADING APP -----
NSLog(#"PLAY SOUND CLIP WHILE LOADING APP");
NSURL *clip = [[NSBundle mainBundle] URLForResource: #"intro" withExtension:#"caf"];
self.startupPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:clip error:NULL];
[self.startupPlayer play]; }
Then in my MainViewController.m
#import "AppDelegate.h"
-(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
//stop intro sound
AppDelegate *introClip = (AppDelegate *)[[UIApplication sharedApplication]delegate];
[[introClip startupPlayer]stop];}
Now even if the intro music is still playing through one cycle, the user can switch to another view and stop that music.
I have quite an understanding issue with displaying local notifications.
As far as I was reading in other threads, one has first create and schedule the local notification with the application.
For displaying that notification, one has to use the delegates didFinishLaunchingWithOptions: (if app is in background operation) and didReceiveLocalNotification: (if app is in foreground).
Now even though I did NOT change the didFinishLaunchingWithOptions: method, the notification is already getting viewed when my app is in the background.
It wouldn't be that big of a problem if the didFinishLaunchingWithOptions: would at least be used when I specify it at all. But it doesn't.
So my problem is, that even though I haven't used the didFinishLaunchingWithOptions: method, the notification is getting displayed. When the user clicks on the notification, the app gets to foreground and the didReceiveLocalNotification: method is triggered and the notification is displayed again.
What I originally wanted to do is to cancelAllLocalNotifications on execution of didFinishLaunchingWithOptions:, but since it is not getting executed, I'm kinda stuck here.
Ok, there might be a workaround with applicationWillEnterForeground: but honestly, I'd like to understand, why the notification is getting displayed even without having specified that in didFinishLaunchingWithOptions:.
All of your help is really appreaciated!! Thanks!!

You are very close. If the app is running in the background, the user responding to the notification will not cause the app to "launch". "Launch" means the app is not running at all (foreground or background). So only put code in there that you want to execute when the app launches or starts as a result of the user responding to your local notification.
So what you need for your didReceiveLocalNotification method is something to check the application state to see if it was in the foreground or in the background when the user responded to the local notification.
You might do something like the following to differentiate your logic between foreground and background:
- (void)application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification
if ( application.applicationState == UIApplicationStateActive ){
NSLog(#"Was already in the foreground");
}
else{
NSLog(#"Was in the background");
}
}
Minor point, however. Documentation states that the didReceiveLocalNotification method is invoked after application:didFinishLaunchingWithOptions: (if that method is implemented). So if you have both methods implemented you'll need to make sure the combination of the 2 work correctly in a "launch" situation.
In the iPad Programming Guide, it gives the following code example for specifying the two views (firstVC and secondVC) that will be used in the SplitView...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
MyFirstViewController* firstVC = [[[MyFirstViewController alloc]
initWithNibName:#"FirstNib" bundle:nil] autorelease];
MySecondViewController* secondVC = [[[MySecondViewController alloc]
initWithNibName:#"SecondNib" bundle:nil] autorelease];
UISplitViewController* splitVC = [[UISplitViewController alloc] init];
splitVC.viewControllers = [NSArray arrayWithObjects:firstVC, secondVC, nil];
[window addSubview:splitVC.view];
[window makeKeyAndVisible];
return YES;
}
but when I actually create a new SplitView project in Xcode, I don't see any code that says the default rootView and detailView views should be added to the SplitView. Where can I find that?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after app launch
rootViewController.managedObjectContext = self.managedObjectContext;
// Add the split view controller's view to the window and display.
[window addSubview:splitViewController.view];
[window makeKeyAndVisible];
return YES;
}
I'm new to iPhone OS programming and I'm just trying to understand how this all works. Thanks in advance for all your help! I'm going to continue researching this question right now.
It's because the links are set up in the *.nib file already. You could still use the .viewControllers approach if you don't want to rely on the *.nib to do it automatically.
