Handle JSON push notification parse when app is not running - ios

I have a problem handling push message send with parse.com, when app is running i can handle json and construct message with:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
But when app is in background or killed, this message is handle and send direct to notification bar. I tried to handle in this function:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
....
UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (localNotif) {
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 99];
UIAlertView *BOOM = [[UIAlertView alloc] initWithTitle:#"BOOM"
message:#"app was INACTIVE"
delegate:self
cancelButtonTitle:#"a-ha!"
otherButtonTitles:nil];
[BOOM show];
NSLog(#"App was NOT ACTIVE");
}
.....
est this responses, but i can't handle push messages:
Handling Push Notifications when App is NOT running
Can't handle push notifications when app is running background
Handling push notifications when app is not running (App is Killed)
how can I handle push notification when my app is not running
Any help ? Thx.

I can't handle notifications when app is not running or in background, i change focus of resolution, i'm doing like android app's but i iOS handle messages with "Message Control" and i don't found "the way" to handle this.
I start to use channels of push notification for subscribe messages depending user settings. I send to Parse messages with channels, and app subscribe channels.
You can send Notification via POST:
curl -X POST \
-H "X-Parse-Application-Id: {APP-KEY}" \
-H "X-Parse-REST-API-Key: {REST-API-KEY}" \
-H "Content-Type: application/json" \
-d '{
"channels": [
"valencia",
"sevilla"
],
"data": {
"alert": "Fin del partido Betis - Valencia 0-2",
"sound": "gol.mp3"
}
}' \
https://api.parse.com/1/push
In App you can subscribe to channels in AppDelegate:
- (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];
NSArray * channels = #[#"channel1", #"channel2"];
NSLog(#"Channels : %#", channels);
currentInstallation.channels = channels;
[currentInstallation saveInBackground];
}
You can change channels anywhere, like this:
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
currentInstallation.channels = #[#"channel3"];
[currentInstallation saveInBackground];
Maybe this can help someone.

Add your code to this function, when app is killed and you get push notification - it will call this function so that you can relaunch your app on this notification and show alert with in a application accordingly.
(void)application:(UIApplication *)app didReceiveRemoteNotification:(NSDictionary *)userInfo

Parse Push Notification Get Notification Channel - iOS

i recently set up push notifications for my app using Parse. I have been able to get the notifications and the data sent but now i want to get the channel to which the notification has been sent. Is there any way to do so in ios?
Have you checked this guide? It's really helpful.
https://www.parse.com/tutorials/ios-push-notifications
Here's a quick summary. Create development and production certificates and then attach them to your developer account for the app that you want to be able to send pushes to. After attaching these certificates redownload them, change them to .p12 files w Keychain Access and then upload them to Parse.com. In Xcode make sure to go into your account via preferences and refresh it so you'll have an updated provisioning profile. I'd do this in the stable version of Xcode and not the beta.
Finally after doing all that you can start coding. In your app delegate attach this code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
...
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge |
UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
...
}
Please note that the following code demonstrates how to add a user to a channel... This is Parse's default code and I actually suggest tweaking it a bit. They set it up so that your channels will be reset to global every time the application is launched. I'm not sure that you even need to invoke the method "registerUserNotificationSetting" at all after attaching the device's token to the backend. Take not this method will generate an API request...
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
// This is Parse's default code
currentInstallation.channels = #[ #"global" ];
// I would change it to something like this
if (currentInstallation.channels.count == 0) {
currentInstallation.channels = #[ #"global" ];
}
[currentInstallation saveInBackground];
}
Finally the last bit of code just deals with what the application does if it receives a notification while in the foreground:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
}
Good luck!
When you send the notification just add the channel name to the notifications data.
For example:
PFPush *push = [[PFPush alloc] init];
[push setChannel:#"my_channel"];
NSDictionary *data = #{#"alert":#"Hi there.",#"channel":#"my_channel"};
[push setData:data];
[push sendPushInBackground];
When you receive the notification you can simple get the channel from the payload/userInfo:
NSString *channel = payload[#"channel"];

Are Parse push notifications very unreliable? Only 50% of mine are received

I am building an app that will implement a Parse backend to send push notifications. Users will be able to send other users a message contained in a push notification. I have been playing around with this and when I send it registers on the Parse website fine but only about 50% of the messages sent are being received on the device. Does anyone else have this problem? I know Push Notifications are not guaranteed but a 50% success rate? Any ideas?
Thanks
code below:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[Parse setApplicationId:#"***"
clientKey:#"****"];
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge |
UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
return YES;
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
currentInstallation.channels = #[ #"global" ];
[currentInstallation saveInBackground];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
[PFPush handlePush:userInfo];
}
- (void)notifyFriendAtIndex:(NSInteger)index completionHandler:(userCompletionHandler)handler
{
PFQuery *pushQuery = [PFInstallation query];
[pushQuery whereKey:#"deviceType" equalTo:#"ios"];
NSString *pushMessage = [NSString stringWithFormat:#"From %# HI!", self.currentUser.username];
NSDictionary *pushData = #{#"alert": pushMessage, #"badge": #0, #"sound": #"notify.wav"};
PFPush *push = [[PFPush alloc] init];
[push setQuery:pushQuery];
[push setData:pushData];
[push sendPushInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
NSLog(#"Error: %# %#", error, [error userInfo]);
handler(NO, error);
}
else {
handler(YES, nil);
}
}];
}
I have not experienced any major problems in the past with Parse's Push Notification delivery. One of my apps has about 32,000 registered devices and seems to get near 100% delivery.
I also have a couple of chat apps that use Parse as the messaging and push back-end. Users can subscribe to a particular chat room and get Push Notification through Segmentation. One of those apps just launched and so far the push notifications are coming through 100%. The only thing I've noticed is a slight delay sometimes. Maybe a minute or two, but I think that could be because of a slow wifi connection.
I also use PushWoosh for general Broadcast Push Notifications. They are great, but sometimes PushWoosh takes longer to deliver. Parse is usually faster so the bottom line is I think Parse's Push Notifications are reliable.
In my experience, i concluded that most is due the main push notification deliverer ( Apple for iOS, Google for Android ). I'm saying this because we have an app in Parse that send push notification on both iOS and Android, and some days we don't receive any push notification, some others a few or all. All this without changing any implementation. In past, i used another push notification service called Urban Airship (that rely on the proper push notification deliverers), and there was the same problem, some days "almost" ok, some other no work.
Just check if your testing device are correctly registered in the "Installation" table with proper deviceToken set. We send the push notification server side through channels. I write here the code maybe it could help you:
var dataStruct ={
alert: "Hi there!",
my_additional_info: "normal chat message"
};
Parse.Push.send({
channels: ["your_custom_registered_installation_channel_device"],
data: dataStruct
}).then(function() {
promise.resolve();
}, function(error) {
promise.reject(error);
});
So normally it depends by the day, but if you have this statistic (50%) maybe the installation is not always registered/updated when your iPhone register for push notification
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
// Save/update device tocken
[currentInstallation setDeviceTokenFromData:deviceToken];
// store your channel
[currentInstallation setChannels:#["channel_123"]];
[currentInstallation saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
// Do your stuff
}];
}

Swaping the in-app alertview notification with the banner view when using Parse Push

I was wondering if there is a way to swap out the alertview style notification that happens when a user is inside the app when the notification occurs, to the banner notification style (which one would get if another app is active while receiving the push).
I am using the recommended Parse Push Notifications configuration as the following, but am unsure where I could make these changes (or that if its possible) - thanks for your help!
//In didFinishLaunchingWithOptions
[application registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];
//In appDelegate.m
- (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];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
}
You can't. You need to create and configure your own view and display it (explicitly add and remove it as a subview when you want is on and off screen). This means not calling handlePush: and instead running your own code to display your own view.

App doesn't receive remote notification when it is not running

My app doesn't receive push notifications when it's not running.
I am trying to handle remote notification sent as JSON and update data in my app using data from given JSON.
All is going well when app is active or in background.
But when app is not running, app is processing notifications only when I open my app by tapping on notification, but not when I open app by tapping on icon.
Here is the code from appDelegate class:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[Parse setApplicationId:appId
clientKey:clKey];
if (application.applicationState != UIApplicationStateBackground) {
BOOL preBackgroundPush = ![application respondsToSelector:#selector(backgroundRefreshStatus)];
BOOL oldPushHandlerOnly = ![self respondsToSelector:#selector(application:didReceiveRemoteNotification:fetchCompletionHandler:)];
BOOL noPushPayload = ![launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) {
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
}
}
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|
UIRemoteNotificationTypeAlert|
UIRemoteNotificationTypeSound|
UIRemoteNotificationTypeNewsstandContentAvailability];
NSDictionary *notificationPayload = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
[self processPushNotification:notificationPayload foreground:YES];
return YES;
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
TFLog(#"didRegisterForRemoteNotificationsWithDeviceToken");
// Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
[currentInstallation saveInBackground];
TFLog(#"deviceToken: %#, currentInstallation.badge: %ld", currentInstallation.deviceToken, (long)currentInstallation.badge);
TFLog(#"deviceToken: %#, deviceType: %#", currentInstallation.deviceToken, currentInstallation.deviceType);
TFLog(#"installationId: %#", currentInstallation.installationId);
}
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
TFLog(#"didFailToRegisterForRemoteNotificationsWithError %#", error);
if (error.code == 3010) {
TFLog(#"Push notifications are not supported in the iOS Simulator.");
} else {
// show some alert or otherwise handle the failure to register.
TFLog(#"application:didFailToRegisterForRemoteNotificationsWithError: %#", error);
}
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
TFLog(#"%#", userInfo);
[PFPush handlePush:userInfo];
[self processPushNotification:userInfo foreground:YES];
[PFAnalytics trackAppOpenedWithRemoteNotificationPayload:userInfo];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
TFLog(#"didReceiveRemoteNotification2");
[self processPushNotification:userInfo foreground:YES];
[PFAnalytics trackAppOpenedWithRemoteNotificationPayload:userInfo];
}
As result, app is receiving remote notification in all states, excepting when it is not running.
What have I missed?
You have missed the bit in the Local and Push Notification Programming Guide where it says -
If the action button is tapped (on a device running iOS), the system
launches the application and the application calls its delegate’s
application:didFinishLaunchingWithOptions: method (if implemented); it
passes in the notification payload (for remote notifications) or the
local-notification object (for local notifications).
If the application icon is tapped on a device running iOS, the
application calls the same method, but furnishes no information about
the notification
Also, this note from Apple -
Important: Delivery of notifications is a “best effort”, not
guaranteed. It is not intended to deliver data to your app, only to
notify the user that there is new data available.
If your application is launched from the app icon rather than the notification you need to check for updated content independent of any push notification that may have been received. This enables an application to behave differently when it opens from a notification and when it is opened from the app icon.
For example, the Facebook app opens directly to the item in the notification when launched from the notification alert but not when launched from the app icon - which is the "correct" behaviour from a user point of view. If I interact with the notification then I am interested in its content. If I launch the app from the icon then I just want to use the app - I can then access the notifications in the app if I want.
There's no way you can get the information about your push notification JSON payload when you launch the app by explicitly tapping the app icon.
That's as per Apple's design. When you open the application from any push notification action, then you can retrieve the push notification in application: didFinishLaunchingWithOptions: delegate method. Typically you look up for the UIApplicationLaunchOptionsRemoteNotificationKey key in your launchOptions dictionary.
But, when you open the app by explicitly tapping the application icon, though still the application: didFinishLaunchingWithOptions: delegate will be called, the UIApplicationLaunchOptionsRemoteNotificationKey key will return nil.

Add alertview in application when you recive push notification

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
