ios - didReceiveRemoteNotification not called in Background Mode

Question

I am working on push notifications and the data I receive is in JSON format. How can I parse the JSON data, which is shown in the Notification Center below:

Answer 1

if your app in background/foreground mode call this method

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler

if you used the above method you will face the following error in console

application:didReceiveRemoteNotification:fetchCompletionHandler:], but you still need to add "remote-notification" to the list of your supported UIBackgroundModes in your Info.plist.

To Resolve this issue

follow the image of steps

if your app in foreground mode call this method

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo

choice no-2

   - (void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
  UIApplicationState state = [application applicationState];
    // user tapped notification while app was in background
if (state == UIApplicationStateInactive || state == UIApplicationStateBackground) {
     // go to screen relevant to Notification content
} else {
     // App is in UIApplicationStateActive (running in foreground)
     // perhaps show an UIAlertView
}
}

Swift

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
var state: UIApplicationState = application.applicationState()
// user tapped notification while app was in background
if state == .Inactive || state == .Background {
    // go to screen relevant to Notification content
}
else {
    // App is in UIApplicationStateActive (running in foreground)
    // perhaps show an UIAlertView
}
}
