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

enter image description here

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
}
}
