iOS Push Notifications handle

Looking for a good practice regarding push notifications handle. currently in my app i'm handling the push notifications in the didFinishLaunchingWithOptions and in the didReceiveRemoteNotification delegates. I noticed that both handling logics are "firing" when i receive a push notifications when the app is "Dead". My remote notifications flag in Background Modes is ON in my app. Is there a good practice for handling this scenario ? why am i getting the push data in the didFinishLaunchingWithOptions(launchOptions) and didReceiveRemoteNotification is getting called too ? to my knowledge the didReceiveRemoteNotification is not spoused to get called when the app is "Dead".
