title: APN (Apple Push Notification) payload size limit
body: <p>In <a href="https://developer.apple.com/library/IOs/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html">official documentation</a> you can find the info:</p>
  
  <blockquote>
    <p>Each push notification includes a payload. The payload contains
    information about how the system should alert the user as well as any
    custom data you provide. The maximum size allowed for a notification
    payload is <strong>256 bytes</strong>; Apple Push Notification Service refuses any
    notification that exceeds this limit.</p>
  </blockquote>
  
  <p>However in WWDC 14 we can see this screenshot:</p>

  <p>I wonder if there is any official Apple statement about the size limit of push notification. I tested it and larger that 256 bytes works, but documentation said it shouldn't. Can someone confirm or deny the size of remote notifications?</p>
