omgwtfbbq on "Removing menu items iOS app"

I am trying to remove "Reader" and "Notifications" from the main menu of the open source app for iOS.

I managed to remove them by deleting the "readerNavigationController" and the "notificationNavigationController" from WordPressAppDelegate.m on line 489, but this creates another problem. When I create a new post from the posts menu, the App crashes and closes.

Does anyone have an idea for removing menu items ?

Please please please :-)

Thank you
