 <p>There seems to be a character limit for iOS push notifications based on the type of notification. These values can be seen in a similar Stackoverflow question:</p> <p><a href="http://stackoverflow.com/questions/6307748/what-is-the-maximum-length-of-a-push-notification-alert-text">What is the maximum length of a Push Notification alert text?</a></p> <blockquote> <p><strong>Alerts</strong>: Prior to iOS 7 the alerts display limit was 107 characters. Bigger messages were truncated and you would get a "..." at the end of the displayed message. With iOS 7 the limit seems to be increased to 235 characters. If you go over 8 lines your message will also get truncated.</p> <p><strong>Banners</strong>: Banners get truncated around 62 characters or 2 lines.</p> <p><strong>Notification Center</strong>: The messages in notification center get truncated around 110 characters or 4 lines.</p> <p><strong>Lock Screen</strong>: Same as notification center.</p> </blockquote> <p>I would also recommend looking further into the Push Notification documentation provided by Apple:</p> <p><a href="https://developer.apple.com/library/mac/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html" rel="nofollow">Apple Push Notification Service</a></p>
