Silent push notification - ios

Question

Just wanted a confirmation. Does the app ask for user permission if i have used silent push notification service like it use to ask when push notification was used. Any help would be appreciated

Answer 1

No. It's silent, meaning it works in the background, without user confirmation at the time of the notification.
At app install it asks for confirmation like a normal push notification.

Answer 2

For silent push you have to set JSON like this (php file),
$body['aps'] = array(
'sound' => '',
'content-available' => 1
);
don't send alert and badge.
In xcode file select target -> capabilities and enable background modes and tick remote notification
in appdelegate.m file just use this message to receive silent push
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
{
//Success this method will automatically call when device receives push notification
handler(UIBackgroundFetchResultNewData);
}
// eg code to register for apps
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
if ([application respondsToSelector:#selector(registerUserNotificationSettings:)]) {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
|UIRemoteNotificationTypeSound
|UIRemoteNotificationTypeAlert) categories:nil];
[application registerUserNotificationSettings:settings];
} else {
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[application registerForRemoteNotificationTypes:myTypes];
}
return YES;
}
#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
//register to receive notifications
[application registerForRemoteNotifications];
}
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
{
//handle the actions
if ([identifier isEqualToString:#"declineAction"]){
}
else if ([identifier isEqualToString:#"answerAction"]){
}
}
#endif
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
NSLog(#"My token is: %#", deviceToken);
}
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
