How to hide push notification in ios?

https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html You can refer the above link to Know about the payload of push notification. For not showing push notification you need to pass the payload without alert. If you want a silent notification set Content-available as 1. It'll help.

Eg:

{"aps" : {

        "content-available" : 1
    },

    "YourData":""
}
